The Hurricane Hunters:  The Aircraft That Can Punch Through Category 5 Hurricanes

Posted on by Collective Weather

Hurricane Hunters are specially equipped aircraft used to fly into tropical cyclones to gather critical meteorological data. These missions provide invaluable information that helps meteorologists predict the path, intensity, and potential impact of hurricanes. The aircraft used in these daring missions are heavily modified to withstand the extreme conditions encountered in the eyewall of a hurricane, the most intense part of the storm. This article explores the unique features and modifications of Hurricane Hunter aircraft, and how they accomplish their challenging mission.

The Role of Hurricane Hunter Aircraft

Hurricane Hunters are tasked with penetrating the core of hurricanes to collect data that cannot be obtained by satellites or ground-based instruments. These aircraft fly directly into the storm, gathering real-time data on wind speeds, pressure, temperature, humidity, and other critical parameters. This information is essential for improving hurricane forecasts, which can save lives and reduce economic losses.

Key Aircraft in the Hurricane Hunter Fleet

The most commonly used Hurricane Hunter aircraft include the Lockheed WP-3D Orion and the WC-130J Hercules. These planes are operated by the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Air Force Reserve’s 53rd Weather Reconnaissance Squadron, respectively.

Lockheed WP-3D Orion

The WP-3D Orion, also known as “Miss Piggy” and “Kermit,” are two modified versions of the P-3 Orion, originally designed for anti-submarine warfare. These aircraft have been extensively modified to serve their new role in hurricane reconnaissance.

WC-130J Hercules

The WC-130J Hercules is a weather reconnaissance version of the C-130J Super Hercules. This aircraft is operated by the 53rd Weather Reconnaissance Squadron, known as the “Hurricane Hunters.” The WC-130J is equipped with sophisticated instruments to collect meteorological data while enduring the harsh conditions of a hurricane.

Modifications and Special Features

Hurricane Hunter aircraft undergo several modifications to ensure they can safely and effectively operate in the extreme conditions encountered within a hurricane. These modifications include structural reinforcements, specialized instrumentation, and enhanced communication systems.

Structural Reinforcements

  1. Enhanced Airframe: The airframe of Hurricane Hunter aircraft is reinforced to withstand the intense turbulence, high winds, and potential impact of debris encountered in the eyewall. The reinforcement includes strengthening the wings, fuselage, and control surfaces.
  2. De-Icing Systems: Given the varying altitudes and temperatures the aircraft experience, advanced de-icing systems are crucial to prevent ice buildup on the wings and control surfaces, which could jeopardize the mission.

Specialized Instrumentation

  1. Dropsondes: These are small, expendable devices dropped from the aircraft into the hurricane. As a dropsonde descends, it measures and transmits data on temperature, humidity, pressure, and wind speed and direction. This vertical profile of the atmosphere provides critical information about the structure of the storm.

2. Stepped-Frequency Microwave Radiometer (SFMR): This instrument measures the wind speed at the surface of the ocean by detecting microwave emissions from the sea surface. The SFMR allows scientists to estimate the intensity of the storm over water, which is essential for accurate forecasting.

3. Radar Systems: Advanced radar systems, including tail Doppler radar and lower fuselage radar, are used to map the structure of the hurricane. These radar systems provide detailed information on the eyewall, rainbands, and overall storm morphology.

4. Airborne Vertical Atmospheric Profiling System (AVAPS): This system works in conjunction with dropsondes to provide vertical atmospheric profiles, enhancing the understanding of atmospheric dynamics within the storm.

Enhanced Communication Systems

  1. Satellite Communication: Real-time data transmission is crucial for Hurricane Hunters. Satellite communication systems allow the aircraft to send data directly to the National Hurricane Center (NHC) and other meteorological agencies. This ensures that forecasters receive up-to-date information to improve their models and predictions.
  2. Advanced Navigation Systems: Precision navigation is essential for flying into and out of the turbulent environment of a hurricane. Enhanced GPS and inertial navigation systems ensure accurate positioning, allowing the aircraft to safely navigate through the storm.

The Eyewall Challenge

The eyewall of a hurricane is the region surrounding the eye of the storm, characterized by the most intense winds and heaviest rainfall. Flying through the eyewall is one of the most challenging and dangerous aspects of a Hurricane Hunter mission.

Turbulence and Wind Shear

The eyewall features extreme turbulence and wind shear, which can create severe stress on the aircraft. Pilots must be highly skilled to manage these conditions, maintaining control of the aircraft while ensuring the safety of the crew and the integrity of the data being collected.

Lightning and Electrical Hazards

Hurricanes often generate significant electrical activity, including lightning. Hurricane Hunter aircraft are equipped with lightning protection systems to minimize the risk of electrical damage. These systems include static discharge wicks and shielding for electronic components.

Communication with Ground Stations

Maintaining communication with ground stations is vital during a mission. Despite the extreme conditions, Hurricane Hunter aircraft are equipped with robust communication systems to ensure continuous data transmission and coordination with meteorological agencies.

Case Studies: Missions into Major Hurricanes

Hurricane Katrina (2005)

During Hurricane Katrina, Hurricane Hunter aircraft played a crucial role in monitoring the storm’s development and intensification. Data collected from these missions helped forecasters accurately predict the catastrophic impact of the storm, prompting timely evacuations and disaster preparations.

Hurricane Harvey (2017)

Hurricane Hunters were instrumental in tracking Hurricane Harvey, which brought unprecedented rainfall and flooding to Texas. The data collected by the aircraft provided critical insights into the storm’s behavior, enabling more accurate forecasts and effective emergency response efforts.

1. Hurricane Hugo (1989) – NOAA WP-3D Orion Incident

In September 1989, a NOAA WP-3D Orion aircraft, tail number N42RF (nicknamed “Kermit”), flew into Hurricane Hugo, which was a Category 5 storm at the time. The aircraft encountered severe turbulence and extreme wind shear. During the mission, the aircraft experienced a significant drop in altitude due to powerful downdrafts. The crew managed to recover the plane and complete the mission, but the incident underscored the extreme dangers of flying into powerful hurricanes.

2. Typhoon Violet (1961) – WB-50D Superfortress Crash

In October 1961, a U.S. Air Force WB-50D Superfortress, part of the 54th Weather Reconnaissance Squadron, was on a mission to gather data on Typhoon Violet. The aircraft encountered severe turbulence and extreme weather conditions in the eyewall. Tragically, the plane crashed into the Pacific Ocean, resulting in the loss of all ten crew members. This incident remains one of the deadliest involving Hurricane Hunter missions and highlights the risks these crews face.

3. Hurricane Janet (1955) – Navy P2V Neptune Crash

In September 1955, a U.S. Navy P2V Neptune aircraft from the VW-4 squadron was on a reconnaissance mission into Hurricane Janet, a Category 5 storm. The aircraft encountered severe turbulence and heavy rain, causing it to crash in the Caribbean Sea. All nine crew members aboard were lost. This crash prompted the military to review and improve safety protocols for Hurricane Hunter missions.

4. Hurricane Patricia (2015) – WC-130J Hercules Incident

During Hurricane Patricia in October 2015, which rapidly intensified to become the most powerful hurricane on record in the Western Hemisphere, a U.S. Air Force Reserve WC-130J Hercules aircraft flew into the storm to gather critical data. The aircraft encountered extreme turbulence and faced significant challenges maintaining altitude and stability. The crew managed to safely navigate through the eyewall, but the mission was a stark reminder of the perils involved in these operations.

5. Hurricane Katrina (2005) – NOAA P-3 Incident

In August 2005, as Hurricane Katrina was intensifying in the Gulf of Mexico, a NOAA P-3 aircraft flew multiple missions into the storm. One particular flight faced severe turbulence and mechanical issues, including problems with one of the engines. Despite these challenges, the crew successfully completed their mission and provided crucial data that helped forecasters predict the storm’s path and intensity. The aircraft landed safely, but the mission highlighted the physical and technical difficulties of hurricane reconnaissance.

Riders on the Storm: The Daredevils Who Chase Hurricanes for Thrills

Posted on by Collective Weather

In the heart of hurricane season, as most people board up their windows and evacuate to safer ground, a select group of adventurers head straight into the eye of the storm. These are the hurricane chasers, a rare breed of meteorologists, scientists, and thrill-seekers who risk their lives to study and experience the raw power of nature’s most destructive forces.

One of the most renowned hurricane chasers is Dr. Josh Morgerman, a meteorologist and storm chaser who has been pursuing hurricanes for over two decades. Morgerman, who founded the hurricane research organization iCyclone, has chased more than 50 hurricanes and typhoons across the globe, including some of the most intense storms in recent history, such as Hurricane Dorian in 2019 and Super Typhoon Haiyan in 2013.

“There’s nothing quite like the experience of being in the eye of a hurricane,” Morgerman says. “It’s a moment of eerie calm in the midst of chaos, and it gives you a profound appreciation for the power and beauty of nature.”

To chase hurricanes, Morgerman and his team rely on a sophisticated array of equipment, including mobile weather stations, anemometers, and satellite phones. They also use specialized vehicles, such as reinforced trucks and SUVs, to navigate through the treacherous conditions of a hurricane’s outer bands.

Another prominent figure in the hurricane chasing community is Mark Sudduth, a former restaurant owner turned storm chaser who founded the website HurricaneTrack.com. Sudduth has been chasing hurricanes since 1999 and has witnessed some of the most devastating storms in recent memory, including Hurricane Katrina in 2005 and Hurricane Michael in 2018.

“Chasing hurricanes is not for the faint of heart,” Sudduth says. “You have to be prepared for anything and everything, from flying debris to storm surges to power outages. But the rewards – the data we collect, the stories we tell, and the lives we potentially save – make it all worth it.”

Sudduth’s hurricane chasing strategy involves deploying a network of remote cameras and weather sensors along the coast, which allows him to gather data and livestream footage of the storm from a safe distance. He also works closely with emergency management officials and local media outlets to provide real-time updates and warnings to communities in the path of the hurricane.

One of the most harrowing hurricane chases in recent memory was the pursuit of Hurricane Michael in October 2018. Michael, a Category 5 storm with maximum sustained winds of 160 mph, made landfall near Mexico Beach, Florida, causing catastrophic damage and claiming the lives of 74 people.

For hurricane chaser Jeff Piotrowski, who has been chasing storms for over 40 years, Hurricane Michael was a once-in-a-lifetime experience. Piotrowski and his team were on the ground in Mexico Beach as the storm made landfall, documenting the destruction with high-definition cameras and live-streaming the footage to millions of viewers around the world.

“The power of that storm was just incredible,” Piotrowski recalls. “We were in the eye wall for over an hour, with winds gusting over 150 mph and debris flying everywhere. It was like being in a war zone.”

Despite the dangers, Piotrowski and his team managed to capture some of the most dramatic footage of Hurricane Michael, including the moment when the storm surge overtook their vehicle and forced them to abandon their equipment and flee to higher ground.

For hurricane chasers, having the right equipment can mean the difference between life and death. To track and forecast the path of a hurricane, chasers rely on a variety of tools, including mobile weather stations, anemometers, barometers, and GPS devices.

One of the most important pieces of equipment for hurricane chasers is the mobile weather station, which allows them to gather real-time data on wind speed, air pressure, temperature, and humidity. These stations are typically mounted on the roof of a vehicle and can withstand winds of up to 200 mph.

Another critical tool for hurricane chasers is the anemometer, which measures wind speed and direction. Handheld anemometers are often used by chasers on the ground, while larger, more sophisticated devices are mounted on vehicles or deployed in strategic locations along the coast.

To forecast the path of a hurricane, chasers rely on a combination of computer models, satellite imagery, and radar data. The National Hurricane Center in Miami, Florida, is the primary source of hurricane forecasts and warnings in the United States, and many chasers work closely with the center to share data and coordinate their efforts.

However, even with the most advanced equipment and forecasting tools, chasing hurricanes is an inherently dangerous pursuit. One of the biggest risks is the storm surge, a wall of water that can rise up to 30 feet or more and sweep away everything in its path. Storm surges are responsible for many of the deaths and much of the damage associated with hurricanes, and chasers must be constantly aware of their location and proximity to the coast.

Another hazard of hurricane chasing is the eyewall, the ring of intense thunderstorms that surrounds the calm eye of the hurricane. Within the eyewall, winds can gust up to 200 mph or more, and tornadoes can form suddenly and without warning. Chasers who venture too close to the eyewall risk being hit by flying debris, blown off the road, or even swept away by the storm surge.

In addition to the risks posed by the storm itself, hurricane chasers must also contend with the logistical challenges of operating in a disaster zone. Roads may be flooded or blocked by debris, power lines may be down, and cell phone service may be spotty or nonexistent. Chasers must be self-sufficient and prepared to survive on their own for days or even weeks at a time.

To mitigate these risks, hurricane chasers rely on a combination of experience, skill, and technology. They carefully plan their routes and staging areas in advance, taking into account factors such as elevation, road conditions, and the availability of shelter. They also carry a wide range of survival gear, including food, water, first aid kits, and satellite phones.

Despite the dangers, many hurricane chasers say that the rewards of their work far outweigh the risks. By gathering data and documenting the power of these storms, they help scientists better understand how hurricanes form and behave, which can ultimately lead to better forecasting and warning systems.

“Chasing hurricanes is not just a job or a hobby for me,” says Mark Sudduth of HurricaneTrack.com. “It’s a calling. It’s a way to witness the awesome power of nature and to help people prepare for and survive these incredible storms.”

Of course, even the most experienced and well-equipped hurricane chasers know that they are ultimately at the mercy of the storm. In 2008, a team of chasers led by meteorologist Sean Casey narrowly escaped death when their specially designed tornado intercept vehicle was flipped over by the powerful winds of Hurricane Ike in Texas.

“We were tumbling end over end, and I thought for sure we were going to die,” Casey recalls. “But somehow, we landed right side up and were able to drive away. It was a miracle.”

For hurricane chasers, close calls like these are just part of the job. But they also serve as a reminder of the awesome power and unpredictability of these storms, and of the importance of respecting the forces of nature.

The Hurricane That Changed Everything: How Galveston Reshaped America

Posted on by Collective Weather

In the book of American history, few natural disasters have left as painful a mark as the Great Galveston Hurricane of 1900. This catastrophic storm, which struck the thriving coastal city of Galveston, Texas, on September 8, 1900, remains the deadliest natural disaster in U.S. history, claiming an estimated 6,000 to 12,000 lives. But beyond the staggering loss of life, the Galveston Hurricane also set in motion a series of events and changes that would reshape the nation in profound and lasting ways.

The Rise of Galveston: To understand the full impact of the 1900 hurricane, you must first appreciate Galveston’s prominence at the turn of the 20th century. Located on a barrier island off the Texas coast, Galveston was a booming port city and a center of commerce, culture, and tourism. Its strategic location made it a hub for shipping and trade, with a bustling harbor that rivaled New York and New Orleans.

Galveston’s prosperity was reflected in its grand architecture and vibrant social scene. The city boasted elegant mansions, opulent hotels, and a thriving red-light district that drew visitors from across the country. Its beaches and mild climate made it a popular resort destination, earning it the nickname “The Playground of the South.”

However, Galveston’s low-lying topography also made it vulnerable to hurricanes and flooding. The city had experienced several close calls with major storms in the past, but had always managed to escape catastrophic damage. This luck would run out on September 8, 1900.

The Storm’s Fury: The hurricane that struck Galveston that fateful September day was a monster by any measure. It packed winds of up to 145 mph (233 km/h) and generated a storm surge of over 15 feet (4.6 meters) that inundated the island. The city, which had an average elevation of just 5 feet (1.5 meters) above sea level, was no match for the storm’s fury.

As the hurricane made landfall, it unleashed a cascade of destruction. Wind-driven debris turned into deadly projectiles, while the storm surge swept away entire neighborhoods. The city’s famed beachfront pavilions and bathhouses were reduced to kindling. The grand mansions of the wealthy were not spared, with many collapsing under the onslaught of wind and water.

The human toll was staggering. An estimated 6,000 to 12,000 people lost their lives, making it the deadliest natural disaster in U.S. history. The majority of the victims were residents of the city’s low-lying areas, many of whom were African American and working-class. Their bodies were found scattered across the island, tangled in debris or washed out to sea.

The Aftermath: In the wake of the hurricane, Galveston was a city in ruins. An estimated 3,600 homes were destroyed, and many more were damaged beyond repair. The city’s infrastructure, including its water and sewer systems, was crippled. The once-thriving port was choked with debris and sunken ships.

The scale of the disaster was hard to fathom, even for those who had lived through it. Clara Barton, the founder of the American Red Cross, arrived in Galveston shortly after the storm and described the scene as “one of the most horrifying sights that ever met my eyes.”

Despite the devastation, the people of Galveston proved resilient. Almost immediately, they began the daunting task of rebuilding their city. Volunteers from across the country poured in to help with the recovery effort, and donations of money and supplies arrived from as far away as Europe and Australia.

However, it soon became clear that rebuilding alone would not be enough to protect Galveston from future storms. The city’s leaders knew that they needed to take drastic measures to ensure the island’s long-term survival.

The Raising of Galveston: One of the most ambitious and innovative responses to the 1900 hurricane was the decision to literally raise the city of Galveston. Engineers proposed a plan to lift the entire grade of the city by several feet, using a combination of dredged sand and a network of seawalls and retaining walls.

The scale of the project was unprecedented. Over the course of several years, more than 2,000 buildings were jacked up on stilts while sand was pumped underneath to raise the ground level. The process was painstaking and expensive, but it proved remarkably effective. By 1911, the grade of the city had been raised by as much as 17 feet (5.2 meters) in some areas.

In addition to raising the city, Galveston also constructed a massive seawall along its beachfront. The 17-foot-tall (5.2-meter) structure, which stretched for over 10 miles (16 kilometers), was designed to protect the city from future storm surges. The seawall proved its worth in 1915, when another major hurricane struck the island. While the storm caused significant damage, the loss of life was a fraction of what it had been in 1900.

A National Wake-Up Call: The Galveston Hurricane of 1900 was not just a local tragedy; it was a national wake-up call. The storm exposed the woeful inadequacy of the country’s weather forecasting and disaster preparedness systems. At the time, there was no national weather service, and the few weather stations that did exist were poorly equipped and understaffed.

The Galveston disaster spurred a major overhaul of the nation’s weather infrastructure. In 1901, Congress passed the Organic Act, which created the U.S. Weather Bureau (the predecessor to today’s National Weather Service). The new agency was tasked with improving weather forecasting and providing timely warnings of impending storms.

The lessons of Galveston also led to significant changes in building codes and land-use policies in coastal areas. Many cities began to adopt stricter building standards and zoning regulations to minimize the risk of storm damage. The use of reinforced concrete and steel became more widespread, as did the practice of elevating structures above potential flood levels.

A Turning Point for American Philanthropy: The Galveston Hurricane also marked a turning point in American philanthropy. The outpouring of support and donations in the aftermath of the storm was unprecedented, and it helped to establish the modern framework for disaster relief and charitable giving.

One of the most significant developments was the emergence of the American Red Cross as the nation’s premier disaster relief organization. Under the leadership of Clara Barton, the Red Cross played a crucial role in the Galveston recovery effort, providing food, shelter, and medical care to thousands of survivors.

The success of the Red Cross in Galveston helped to cement its reputation as a trusted and effective charity, and it paved the way for the organization’s expansion in the decades that followed. Today, the Red Cross remains one of the most recognizable and respected humanitarian organizations in the world.

Galveston’s Legacy: More than a century after the Great Galveston Hurricane, the legacy of the storm can still be felt across the United States. The changes and innovations that emerged in the wake of the disaster – from improved weather forecasting to stronger building codes to more effective disaster relief – have helped to make the nation more resilient in the face of natural hazards.

Inside the Storm: Decoding Radar’s Secrets – From Bow Echo to Debris Ball

Posted on by Collective Weather

Radar meteorology is one of the most important tools for monitoring and predicting severe weather events. By analyzing radar data, meteorologists can identify specific features that indicate the presence of dangerous storms, such as supercell thunderstorms and tornadoes. In this article, we will discuss some of the most common radar features to look for when assessing severe weather threats.

  1. Hook Echo:
    A hook echo is a distinctive radar signature that often indicates the presence of a supercell thunderstorm capable of producing tornadoes. This feature appears as a hook-shaped appendage extending from the main storm cell on the radar display. The hook shape is formed by the rotation of the storm’s updraft, which can cause rain and hail to wrap around the updraft, creating a hook-like appearance.

    When a hook echo is detected, it is essential to monitor the storm closely, as it has a higher likelihood of producing a tornado. The tightness and persistence of the hook echo can provide clues about the storm’s intensity and potential for tornadogenesis. A tight, well-defined hook echo that persists for an extended period is more likely to be associated with a strong, long-lived tornado.

    1. Bow Echo:
      A bow echo is a radar signature that indicates the presence of a strong, linear wind storm known as a derecho. This feature appears as a bow-shaped line of storms on the radar display, with the apex of the bow pointing in the direction of the storm’s movement. Bow echoes are often associated with widespread damaging winds, which can exceed 100 mph in extreme cases.

    The formation of a bow echo is related to the development of a strong rear-inflow jet behind the main line of storms. This jet of fast-moving air descends to the surface and spreads out, causing the line of storms to bow outward. As the rear-inflow jet continues to strengthen, it can lead to the formation of embedded circulations within the line, known as mesovortices, which can produce brief, spin-up tornadoes.

    1. Debris Ball:
      A debris ball, also known as a tornado debris signature (TDS), is a radar feature that indicates the presence of lofted debris associated with a tornado. This signature appears as a localized area of high reflectivity (bright colors) on the radar display, often coinciding with the location of a hook echo or other tornado-related features.

    The debris ball is caused by the tornado lofting large amounts of debris, such as trees, building materials, and other objects, high into the air. When the radar beam intersects this debris, it produces a strong return signal, which appears as a bright, concentrated area on the radar display. The presence of a debris ball is a strong indication that a tornado is causing damage on the ground.

    1. Three-Body Scatter Spike (TBSS):
      A three-body scatter spike is a radar signature that can indicate the presence of a large hail core within a thunderstorm. This feature appears as a narrow, linear spike of high reflectivity extending radially outward from the storm on the radar display. The TBSS is caused by the radar beam reflecting off a layer of large hailstones and then reflecting again off the ground before returning to the radar.

    The presence of a TBSS suggests that the storm contains a significant amount of large hail, which can cause extensive damage to property and pose a serious risk to public safety. When a TBSS is detected, it is important to issue warnings for large hail and to advise people to seek shelter immediately.

    1. Bounded Weak Echo Region (BWER):
      A bounded weak echo region is a radar feature that indicates the presence of a strong, persistent updraft within a thunderstorm. This feature appears as a localized area of low reflectivity (dark colors) surrounded by higher reflectivity values on the radar display. The BWER is caused by the strong updraft lifting precipitation particles high into the storm, creating a region of relatively low radar returns.

    The presence of a BWER suggests that the storm has a powerful updraft, which can support the formation of large hail and tornadoes. When a BWER is detected, it is important to monitor the storm closely for the development of other severe weather signatures, such as hook echoes or debris balls.

    1. Inflow Notch:
      An inflow notch is a radar signature that indicates the presence of strong, localized inflow into a thunderstorm. This feature appears as a small, localized area of low reflectivity (dark colors) along the leading edge of the storm on the radar display. The inflow notch is caused by the rapid inflow of warm, moist air into the storm, which can fuel the development of strong updrafts and severe weather.

    The presence of an inflow notch suggests that the storm is actively ingesting warm, moist air, which can lead to rapid intensification and the formation of severe weather hazards, such as large hail, damaging winds, and tornadoes. When an inflow notch is detected, it is important to monitor the storm closely for the development of other severe weather signatures.

    1. Rear Inflow Notch (RIN):
      A rear inflow notch is a radar feature that indicates the presence of strong, localized inflow into the back side of a thunderstorm. This feature appears as a small, localized area of low reflectivity (dark colors) along the rear flank of the storm on the radar display. The RIN is caused by the rapid inflow of cooler, drier air into the storm, which can help to strengthen the storm’s updraft and increase the potential for severe weather.

    The presence of a RIN suggests that the storm is actively ingesting cooler, drier air on its back side, which can lead to the formation of a strong rear-flank downdraft (RFD). The RFD can help to tighten the storm’s rotation and increase the risk of tornadogenesis. When a RIN is detected, it is important to monitor the storm closely for the development of hook echoes, debris balls, and other tornado-related signatures.

    1. Hail Spike:
      A hail spike is a radar signature that indicates the presence of a strong updraft capable of producing large hail. This feature appears as a narrow, vertical spike of high reflectivity extending upward from the storm on the radar display. The hail spike is caused by the strong updraft lofting large hailstones high into the storm, where they can grow even larger before falling back to the ground.

    The presence of a hail spike suggests that the storm has a powerful updraft that can support the formation of large, damaging hail. When a hail spike is detected, it is important to issue warnings for large hail and to advise people to seek shelter immediately.

    Hurricanes and Climate Change: Is There a Connection?

    Posted on by Collective Weather

    As the world grapples with the increasingly visible effects of climate change, one question that often arises is whether there is a link between global warming and the frequency and intensity of hurricanes. To shed light on this complex issue, we spoke with leading climate scientists and examined the latest research on the subject.

    The Basics of Hurricane Formation:


    Before going into the potential connection between hurricanes and climate change, it’s key to understand how these powerful storms form. Hurricanes, also known as tropical cyclones, are fueled by warm ocean waters and low wind shear. As warm, moist air rises from the ocean surface, it creates an area of low pressure, which draws in more air from surrounding areas. This process continues, causing the storm to rotate and intensify.

    Rising Sea Surface Temperatures:


    One of the most significant factors that climate scientists point to when discussing the potential link between hurricanes and climate change is rising sea surface temperatures. According to the National Oceanic and Atmospheric Administration (NOAA), global ocean temperatures have increased by approximately 0.13°F (0.07°C) per decade since 1901. This trend is particularly pronounced in the tropical regions where hurricanes form.

    Dr. James Kossin, a climate scientist at NOAA’s National Centers for Environmental Information, explains, “Warmer ocean temperatures provide more energy for hurricanes to form and intensify. As the climate continues to warm, we expect to see more instances of rapidly intensifying hurricanes, which can be particularly dangerous because they give coastal communities less time to prepare.”

    Increased Water Vapor in the Atmosphere:


    Another factor that may contribute to the intensification of hurricanes is the increased water vapor in the atmosphere due to global warming. As the Earth’s surface temperatures rise, more water evaporates from the oceans and land, leading to higher humidity levels.

    Dr. Kerry Emanuel, a professor of atmospheric science at the Massachusetts Institute of Technology, notes, “The amount of water vapor in the atmosphere has increased by about 7% since the 1970s, which is consistent with the expected effect of global warming. This extra moisture can fuel more intense hurricanes, as well as lead to heavier rainfall during these events.”

    The Debate on Hurricane Frequency:
    While there is growing evidence to suggest that climate change may lead to more intense hurricanes, the question of whether global warming is causing an increase in the frequency of these storms is still a topic of debate among climate scientists.

    A 2015 study published in the journal Nature Climate Change found that the frequency of global hurricane activity has remained relatively stable since the 1970s. However, the study also noted that the proportion of Category 4 and 5 hurricanes—the most intense storms on the Saffir-Simpson scale—has increased significantly during this period.

    Dr. Tom Knutson, a research meteorologist at NOAA’s Geophysical Fluid Dynamics Laboratory, cautions, “While we have not seen a clear trend in the overall frequency of hurricanes, it’s important to recognize that even a small increase in the proportion of the most intense storms can have devastating consequences for coastal communities.”

    Recent Hurricane Seasons:
    The 2020 Atlantic hurricane season was one of the most active on record, with 30 named storms, 13 of which reached hurricane strength. This season also saw a record-breaking 12 landfalling storms in the United States, causing billions of dollars in damage and claiming dozens of lives.

    While it’s difficult to attribute any single hurricane season to climate change, Dr. Kossin points out, “The 2020 season exhibited many of the characteristics we expect to see more of in a warming world, such as rapidly intensifying storms and increased rainfall rates. It’s a reminder that we need to be prepared for more extreme hurricane seasons in the future.”

    The Need for Further Research:
    Despite the growing body of evidence suggesting a link between climate change and hurricane intensity, climate scientists stress the need for continued research to better understand this complex relationship.

    Dr. Emanuel emphasizes, “While we have made significant progress in understanding how global warming may affect hurricanes, there are still many uncertainties. We need to invest in more advanced modeling techniques and observational tools to improve our ability to predict and prepare for these storms.”

    Recent hurricanes:

    1. 2023: 8 hurricanes, highest category – Category 5 (Hurricane Lee)
    2. 2022: 8 hurricanes, highest category – Category 4 (Hurricane Ian)
    3. 2021: 7 hurricanes, highest category – Category 4 (Hurricane Ida)
    4. 2020: 14 hurricanes, highest category – Category 4 (Hurricane Iota)
    5. 2019: 3 hurricanes, highest category – Category 5 (Hurricane Dorian)
    6. 2018: 8 hurricanes, highest category – Category 5 (Hurricane Michael)
    7. 2017: 10 hurricanes, highest category – Category 5 (Hurricane Irma and Hurricane Maria)
    8. 2016: 7 hurricanes, highest category – Category 5 (Hurricane Matthew)
    9. 2015: 4 hurricanes, highest category – Category 4 (Hurricane Joaquin)
    10. 2014: 6 hurricanes, highest category – Category 4 (Hurricane Gonzalo)
    11. 2013: 2 hurricanes, highest category – Category 1 (Hurricane Humberto and Hurricane Ingrid)

    For comparison here’s the 1980s:

    1. 1989: 7 hurricanes, highest category – Category 4 (Hurricane Hugo)
    2. 1988: 5 hurricanes, highest category – Category 3 (Hurricane Gilbert)
    3. 1987: 3 hurricanes, highest category – Category 3 (Hurricane Emily)
    4. 1986: 4 hurricanes, highest category – Category 3 (Hurricane Bonnie)

    How Hurricanes Form: The Genesis of a Cyclone

    Posted on by Collective Weather

    The birth of a hurricane is a fascinating process, often starting from inconspicuous beginnings that evolve into powerful storms capable of wreaking havoc. Let’s delve into the early stages of hurricane development, where seemingly innocuous atmospheric disturbances transform into organized systems with the potential for destruction.

    Tropical Wave: The Seed of a Storm

    The journey often begins with a tropical wave, an elongated area of low pressure that originates over the warm waters of the tropics, often off the west coast of Africa. These waves, propelled by easterly trade winds, travel westward across the Atlantic Ocean, carrying showers and thunderstorms within their midst. While most tropical waves dissipate harmlessly, some possess the ingredients necessary to evolve into something more ominous.

    • Warm Ocean Waters: Hurricanes draw their energy from warm ocean waters, typically with surface temperatures of at least 80°F (26.5°C). This heat provides the fuel for the storm’s development and intensification.
    • Coriolis Effect: The Earth’s rotation creates a force known as the Coriolis effect, which causes winds to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection plays a crucial role in the cyclonic rotation of hurricanes.
    • Low Vertical Wind Shear: Vertical wind shear refers to the change in wind speed and direction with height. Low wind shear allows the storm to develop and maintain its vertical structure, while high wind shear can disrupt the storm’s organization.
    • Pre-existing Disturbance: A pre-existing weather disturbance, such as a tropical wave or a cluster of thunderstorms, provides the initial seed for hurricane formation.

    Evolution from Disturbance to Depression:

    If a tropical wave encounters these favorable conditions, it can begin to organize and intensify. As thunderstorms cluster around the area of low pressure, a tropical disturbance forms. If the circulation becomes more defined and wind speeds reach up to 38 mph (62 kph), it is classified as a tropical depression.

    The Critical Transition to Tropical Storm:

    The transition from a tropical depression to a tropical storm marks a significant step in the storm’s development. As the wind speeds increase to 39-73 mph (63-118 kph), the storm becomes more organized and develops a distinct cyclonic circulation. At this stage, it receives a name and is officially recognized as a tropical storm, posing a potential threat to land areas within its path.

    Stages of Hurricane Development:

    1. Tropical Disturbance: A cluster of thunderstorms with a weak circulation forms over warm ocean waters.
    2. Tropical Depression: The circulation becomes more organized, and wind speeds reach up to 38 mph (62 kph).
    3. Tropical Storm: Wind speeds increase to 39-73 mph (63-118 kph), and the storm receives a name.
    4. Hurricane: Wind speeds reach 74 mph (119 kph) or higher, and the storm exhibits a well-defined eye surrounded by a ring of intense thunderstorms known as the eyewall.

    Eye and Eyewall Dynamics:

    The eye of the hurricane is a relatively calm area of low pressure surrounded by the eyewall, the region of highest winds and heaviest rainfall. Air rises rapidly in the eyewall, releasing latent heat and fueling the storm’s intensity. The eye forms as a result of the balance between the inward-flowing air and the upward-rising air in the eyewall.

    Factors Influencing Intensity:

    Several factors influence hurricane intensity, including:

    • Sea surface temperatures: Warmer waters provide more energy for the storm to intensify.
    • Ocean heat content: The depth of warm water also plays a role, as deeper warm layers provide more sustained energy for the hurricane.
    • Atmospheric moisture: Higher moisture content in the atmosphere can fuel stronger thunderstorms and contribute to intensification.
    • Upper-level atmospheric conditions: Favorable upper-level winds can help vent the storm and promote further intensification.

    Understanding Hurricane Categories and Associated Damage

    Hurricane categories, based on the Saffir-Simpson Hurricane Wind Scale, classify these storms based on their maximum sustained wind speeds and the potential damage they can inflict. This scale helps communicate the severity of a hurricane and guide preparedness efforts.

    Category 1 (74-95 mph):

    • Damage: Primarily to trees and foliage, with some damage to roofs, siding, and unanchored mobile homes. Power outages are likely.
    • Historical Examples: Hurricane Gaston (2004), Hurricane Humberto (2019)

    Category 2 (96-110 mph):

    • Damage: Extensive damage to trees and foliage, with significant damage to roofs, siding, and mobile homes. Power outages can last for days or weeks.
    • Historical Examples: Hurricane Frances (2004), Hurricane Zeta (2020)

    Category 3 (111-129 mph):

    • Damage: Devastating damage to trees and foliage, with major damage to roofs, siding, and mobile homes. Structural damage to small buildings is possible. Power and water outages can last for extended periods.
    • Historical Examples: Hurricane Katrina (2005), Hurricane Irma (2017)

    Category 4 (130-156 mph):

    • Damage: Catastrophic damage to trees and foliage, with severe damage to well-built homes. Roofs can be completely torn off, and exterior walls can collapse. Power outages can last for weeks or even months. Extensive coastal flooding and inland flooding are expected.
    • Historical Examples: Hurricane Harvey (2017), Hurricane Maria (2017)

    Category 5 (157 mph or higher):

    • Damage: The most catastrophic damage, with complete roof failure and wall collapse on many residential and industrial buildings. Most trees will be snapped or uprooted. Power outages can last for months, and areas may be uninhabitable for extended periods.
    • Historical Examples: Hurricane Andrew (1992), Hurricane Michael (2018)

    The Midwest Derecho: An Unforgettable Tempest’s Trail of Wind Destruction (August 10, 2020)

    Posted on by Collective Weather

    The date August 10, 2020, is etched in the memories of millions across the Midwest, a day when the skies unleashed a tempest of unimaginable fury. A derecho, a powerful and expansive windstorm, ripped through the heartland, leaving a trail of devastation that stretched from South Dakota to Ohio. This wasn’t just a storm; it was a meteorological monster, its ferocity exceeding expectations and its impact leaving communities reeling in its wake.

    The storm’s genesis lay in the atmospheric instability brewing over South Dakota and Nebraska. Thunderstorms erupted, fueled by a potent mix of warm, moist air and strong upper-level winds. These storms, initially isolated, began to coalesce into a line, forming a squall line, a telltale sign of a developing derecho. This line of storms, propelled by the jet stream, raced eastward at speeds exceeding 70 mph, evolving into a meteorological juggernaut.

    Iowa found itself directly in the derecho’s path, bearing the brunt of its wrath. Wind gusts of up to 140 mph, equivalent to a Category 4 hurricane, tore through cities and towns. Cedar Rapids, a city of over 130,000, was particularly devastated. The winds, relentless and unforgiving, peeled roofs off buildings, tossed vehicles like rag dolls, and uprooted centuries-old trees. The city’s landscape was transformed into a scene of utter chaos, with debris littering the streets and power lines dangling precariously.

    The derecho’s impact extended far beyond Cedar Rapids. Across Iowa, an estimated 14 million acres of cropland were damaged or destroyed, representing roughly a third of the state’s corn and soybean crops. The agricultural industry, the backbone of Iowa’s economy, suffered a staggering blow, with losses estimated in the billions of dollars. The storm’s fury also left millions without power, plunging homes and businesses into darkness and disrupting daily life for weeks.

    In Cedar Rapids, Iowa, the derecho’s arrival was swift and brutal. At approximately 11:15 am, the sky turned an ominous green as the leading edge of the storm approached. Within minutes, the city was engulfed in a maelstrom of wind and rain. Residents huddled in basements and interior rooms as the deafening roar of the wind filled the air. Trees snapped like twigs, roofs were peeled off buildings, and debris flew through the air like missiles. One resident recounted the terrifying experience of watching a large tree crash through his living room window, narrowly missing him and his family.

    The storm’s impact on rural communities was equally devastating. Farmers watched in disbelief as their corn and soybean fields, once lush and green, were flattened in a matter of minutes. Grain bins were crumpled like soda cans, and barns and outbuildings were reduced to piles of debris. One farmer, who had worked the land for over 50 years, described the scene as “total devastation,” his livelihood wiped away in an instant. The derecho’s impact on agriculture reverberated throughout the region, disrupting supply chains and causing food prices to rise.

    As the derecho continued its eastward rampage, it maintained its intensity, leaving its mark on Illinois, Indiana, and Ohio. Chicago experienced wind gusts exceeding 90 mph, causing widespread power outages and bringing the city’s bustling transportation system to a standstill. In Indiana, the storm spawned several tornadoes, adding to the destruction. Even as the derecho weakened, it continued to produce damaging winds and heavy rain, extending its reach over 770 miles and impacting millions.

    The meteorological intricacies that birthed and sustained this derecho were complex. A key factor was the presence of a strong upper-level jet stream, which provided the necessary wind shear to organize the thunderstorms into a line and propel them forward at breakneck speeds. Additionally, a pre-existing mesoscale convective system (MCS), a large cluster of thunderstorms, served as the derecho’s building block, providing a source of lift and moisture.

    As the derecho matured, it developed a bow echo, a characteristic radar signature associated with destructive straight-line winds. The bow echo, shaped like an archer’s bow, indicated the presence of a powerful downdraft, which spread out upon reaching the ground, generating the hurricane-force winds that ravaged the Midwest. The combination of these factors created a perfect storm, a derecho of unprecedented power and scope.

    Derechos have a long and destructive history in the United States, with several notable events leaving their mark on the nation’s memory. One of the most infamous derechos occurred on June 29, 2012, sweeping across the Mid-Atlantic region and causing widespread damage from Indiana to the East Coast. This derecho, known as the “Super Derecho” due to its exceptional intensity and scope, produced wind gusts exceeding 100 mph and left millions without power. The 2012 derecho traveled over 700 miles and caused an estimated $2.9 billion in damage, highlighting the destructive potential of these powerful windstorms.

    Another significant derecho event occurred on May 8, 1995, impacting a large portion of the Midwest. This derecho, which originated in Kansas, traveled over 1,000 miles and produced wind gusts of up to 120 mph. The storm caused widespread damage to trees, power lines, and structures, leaving over 2 million people without power. The 1995 derecho was particularly notable for its long duration, lasting for over 12 hours, and its extensive path, which stretched from Kansas to the East Coast.

    The Midwest derecho of 2020 stands out for several reasons. Its peak wind gusts of 140 mph were among the highest ever recorded for a derecho, rivaling the intensity of a major hurricane. The storm’s impact on agriculture was particularly severe, with millions of acres of crops damaged or destroyed, causing significant economic losses. Additionally, the derecho’s rapid intensification and relatively short warning time caught many off guard, underscoring the challenges of forecasting and preparing for these powerful windstorms. While derechos are not uncommon in the Midwest, the 2020 event served as a stark reminder of their destructive potential and the importance of remaining vigilant during severe weather events.

    The Midwest derecho of 2020 stands as a stark reminder of the unpredictable and destructive nature of severe weather. Its impact extended far beyond the immediate damage to infrastructure and agriculture, leaving a lasting mark on the lives of millions. The storm exposed vulnerabilities in infrastructure and emergency response systems, prompting a reevaluation of preparedness measures and a call for increased investment in resilient infrastructure. As communities rebuild and recover, the memory of the derecho serves as a powerful motivator to strengthen defenses against future storms and ensure the safety and well-being of those who call the Midwest home.
