      Advancing Severe Weather Detection: The Rise of Dual Polarization Radar in the US

      Posted on by Collective Weather

      Weather radar has always been a cornerstone of meteorological observation and forecasting. Yet, traditional radar systems, while effective, were limited in their ability to decipher the complexities within storms, often leaving meteorologists with an incomplete picture. The advent of dual polarization radar technology marked a paradigm shift, ushering in an era of enhanced precision and understanding in severe weather detection and warnings.

      Understanding the Dual Pol Advantage:

      Traditional weather radars transmit and receive horizontally polarized waves, meaning the waves vibrate parallel to the ground. This provides information about the location and intensity of precipitation but lacks the ability to discern the size, shape, and variety of particles within a storm. Dual polarization technology builds upon this foundation by introducing a second dimension – vertical polarization. By transmitting and receiving both horizontally and vertically polarized waves, dual pol radar paints a more comprehensive picture of the storm environment.

      Transforming Tornado Detection:

      One of the most significant benefits of dual pol technology lies in its ability to enhance tornado detection and warnings. Traditional radar could identify areas of rotation within a storm, suggestive of a possible tornado. However, confirming the presence of a tornado often relied on visual sightings or the detection of debris lofted into the air, both of which could be unreliable or delayed.

      Dual pol radar brought a game-changing advantage: the ability to detect debris fields associated with tornadoes. When a tornado is on the ground, it lifts a variety of objects – from tree limbs and building materials to vehicles and even larger structures. These objects scatter radar waves differently than raindrops or hailstones, creating a distinct signature that dual pol radar can identify. This capability allows meteorologists to confirm the presence of a tornado with greater confidence and issue more timely and accurate warnings, potentially saving lives.

      Sharper Images, Clearer Insights:

      Beyond debris detection, dual pol technology enhances the overall resolution and clarity of radar data. By analyzing the way horizontally and vertically polarized waves interact with precipitation particles, meteorologists can estimate the size and shape of raindrops, hailstones, and snowflakes. This information provides valuable insights into the intensity of precipitation, the potential for flooding, and the type of winter weather expected.

      A Nationwide Upgrade: The Dual Pol Rollout:

      Recognizing the transformative potential of dual polarization technology, the National Weather Service (NWS) embarked on an ambitious endeavor to upgrade its entire network of radars across the United States. The rollout, initiated in 2010 and completed in 2013, involved retrofitting existing radars with dual pol capabilities, ensuring comprehensive coverage for the nation.

      This nationwide upgrade has yielded substantial improvements in severe weather detection and warnings. Studies have shown a significant increase in lead times for tornado warnings and a reduction in false alarms, underscoring the life-saving potential of this technology.

      Beyond Tornadoes: A Multifaceted Tool:

      While the impact of dual pol radar on tornado warnings has been profound, its benefits extend far beyond this realm. The technology has proven invaluable for:

      • Improved Rainfall Estimates: By providing more accurate measurements of rainfall amounts, dual pol data enhances flash flood warnings and supports better water resource management.
      • Winter Weather Monitoring: The ability to differentiate between various types of frozen precipitation, such as snow, sleet, and freezing rain, leads to more precise winter storm forecasts and improved road condition monitoring.
      • Aviation Safety: Dual pol radar aids in identifying hazardous weather phenomena for aviation, including icing conditions and turbulence, contributing to safer air travel.

      The Destructive Power of EF-5 Tornadoes: A Look at the Rarest and Most Devastating Twisters

      Posted on by Collective Weather

      The rarity of EF-5 tornadoes can be attributed to the specific atmospheric conditions required for their formation. These conditions include a combination of strong wind shear, instability, and moisture. The presence of a strong, persistent updraft is also crucial in allowing the tornado to maintain its intensity and reach EF-5 status.

      Here are the last five EF-5 tornadoes recorded in the United States:

      1. Moore, Oklahoma (May 20, 2013): This devastating tornado tragically resulted in 24 fatalities and injured 210 people. The estimated population of Moore at the time was around 55,000.
      2. Joplin, Missouri (May 22, 2011): This catastrophic tornado caused immense destruction, claiming the lives of 158 people and injuring over 1,000. Joplin’s population was approximately 50,000 at the time.
      3. Parkersburg, Kansas (May 4, 2007): This powerful tornado resulted in significant damage and tragically took the lives of 11 people. The estimated population of Parkersburg was around 1,400.
      4. Greensburgh, Kansas (May 4, 2007): On the same day as the Parkersburg tornado, Greensburg was struck by another devastating EF5. The town was almost completely destroyed, with 11 fatalities reported. Greensburg’s population was approximately 1,500.
      5. Bridge Creek-Moore, Oklahoma (May 3, 1999): This intense tornado, part of a larger outbreak, caused widespread damage and resulted in 36 fatalities. The combined population of Bridge Creek and Moore was around 41,000 at the time.

      The El Reno tornado is an example of a tornado exhibiting higher wind speeds than those indicated by the damage-based Enhanced Fujita (EF) Scale rating. In fact, there have been several instances where mobile Doppler radar or close-range dual-polarization (dual-pol) radar data have suggested wind speeds exceeding the EF Scale rating.

      For example, the Chickasha, Oklahoma tornado of May 24, 2011, was rated as an EF-4 based on damage surveys. However, mobile Doppler radar data indicated wind speeds of up to 288 mph (463 km/h), which would have classified it as an EF-5. Similarly, the Tipton, Oklahoma tornado of May 16, 2015, was rated as an EF-3, but mobile radar data suggested wind speeds of up to 247 mph (398 km/h), putting it in the EF-5 range.

      These discrepancies between damage-based ratings and radar-measured wind speeds highlight the limitations of the current EF Scale and the need for a more comprehensive approach to tornado intensity classification. By incorporating mobile and close-range dual-pol radar data, scientists and meteorologists could gain a more accurate understanding of a tornado’s true intensity and potential for damage.

      It is worth noting that the Enhanced Fujita (EF) Scale, introduced in 2007, is an updated version of the original Fujita (F) Scale, which was developed by Dr. Theodore Fujita in 1971. The original F Scale was based on the damage caused by tornadoes to structures and vegetation, with ratings ranging from F0 to F5. However, the F Scale had some limitations, such as its subjective nature and the fact that it did not account for differences in building construction and materials.

      The EF Scale was developed to address these limitations and provide a more consistent and objective approach to tornado intensity classification. The EF Scale still uses damage surveys as the primary basis for ratings, but it also takes into account the quality of construction and the types of materials used in structures. Additionally, the wind speed ranges for each EF rating were adjusted based on the latest scientific understanding of the relationship between wind speeds and damage.

      Despite these improvements, the EF Scale still relies heavily on post-event damage surveys, which can be affected by factors such as the availability of damage indicators and the experience of the survey team. Incorporating mobile and close-range dual-pol radar data into the EF Scale could help to overcome these limitations and provide a more comprehensive and accurate assessment of tornado intensity.

      The impact of EF-5 tornadoes on communities is devastating, with long-lasting effects on infrastructure, economy, and the lives of those affected. The high death tolls associated with these tornadoes can be attributed to the extreme wind speeds, the amount of debris generated, and the difficulty in providing adequate warning and shelter.

      Advancements in tornado forecasting and warning systems have helped to reduce the loss of life from EF-5 tornadoes in recent years. However, the destructive power of these rare twisters remains a significant threat to life and property. Continued research into the formation and behavior of EF-5 tornadoes is crucial in improving our understanding and ability to mitigate their impact on communities.

      Unraveling the Secrets of Severe Weather: The Supercell Composite Parameter and Its Vital Role in Forecasting

      Posted on by Collective Weather

      In the world of meteorology, forecasting severe weather events is a complex and challenging task. To help predict the likelihood of severe thunderstorms and tornadoes, meteorologists rely on various tools and indices. One such tool is the Supercell Composite Parameter (SCP), a powerful indicator that combines multiple atmospheric variables to assess the potential for supercell thunderstorm development. In this article, we will dive deep into the Supercell Composite Parameter, exploring its components, its significance in severe weather forecasting, and how it helps protect lives and property.

      Understanding Supercell Thunderstorms: Before delving into the Supercell Composite Parameter, it’s essential to understand what supercell thunderstorms are and why they are so dangerous. Supercell thunderstorms are highly organized, rotating storms that can produce severe weather hazards such as large hail, damaging winds, and tornadoes. These storms are characterized by a persistent rotating updraft called a mesocyclone, which allows them to maintain their intensity for extended periods. Supercell thunderstorms are responsible for some of the most destructive and deadly severe weather events in history, making their accurate prediction a top priority for meteorologists.

      The Components of the Supercell Composite Parameter: The Supercell Composite Parameter is a mathematical formula that combines several key atmospheric variables to assess the potential for supercell thunderstorm development. The main components of the SCP are:

      1. Convective Available Potential Energy (CAPE): CAPE is a measure of the atmospheric instability, representing the amount of energy available for thunderstorm development. Higher CAPE values indicate a greater potential for strong updrafts and severe weather.
      2. Storm-Relative Helicity (SRH): SRH is a measure of the wind shear in the lower atmosphere, which is crucial for the formation of rotating updrafts in supercell thunderstorms. Higher SRH values suggest a greater likelihood of mesocyclone development and tornado potential.
      3. Bulk Wind Difference (BWD): BWD represents the change in wind speed and direction with height, another important factor in supercell development. Strong wind shear, as indicated by high BWD values, helps to create an environment conducive to supercell formation.
      4. Lifting Condensation Level (LCL): The LCL is the height at which air becomes saturated and condensation begins, leading to cloud formation. Lower LCL heights are associated with a greater potential for tornadoes, as they allow for a more concentrated and intense rotation near the ground.

      The SCP formula combines these variables in a specific way to create a single value that represents the overall potential for supercell thunderstorm development. Higher SCP values indicate a greater risk of severe weather, particularly supercell thunderstorms and tornadoes.

      The Significance of the Supercell Composite Parameter in Severe Weather Forecasting: The Supercell Composite Parameter is a crucial tool for meteorologists in their efforts to predict and warn the public about severe weather events. By analyzing SCP values, forecasters can identify areas where the atmospheric conditions are most favorable for supercell thunderstorm development. This information allows them to issue timely and accurate severe weather watches and warnings, giving people in affected areas the opportunity to take necessary precautions and seek shelter.

      One of the key advantages of the SCP is its ability to provide a comprehensive assessment of the severe weather potential. By combining multiple atmospheric variables into a single value, the SCP offers a more holistic view of the overall risk, rather than relying on individual factors alone. This approach helps to reduce the likelihood of false alarms or missed events, improving the overall accuracy and reliability of severe weather forecasts.

      Real-World Applications and Success Stories: The Supercell Composite Parameter has proven its value in numerous real-world severe weather events. Meteorologists have successfully used the SCP to anticipate and warn the public about impending supercell thunderstorms and tornadoes, saving countless lives and minimizing property damage.

      For example, during the devastating tornado outbreak of April 27, 2011, which affected multiple states in the southeastern United States, the SCP played a crucial role in the forecasting process. Meteorologists recognized the extremely high SCP values across the region, indicating an exceptionally high risk of violent, long-track tornadoes. This information allowed forecasters to issue strongly worded warnings and urge people to take immediate action to protect themselves. While the outbreak still resulted in significant damage and loss of life, the accurate and timely warnings based on the SCP undoubtedly saved many lives.

      Similarly, during the May 20, 2013, tornado outbreak in central Oklahoma, the SCP once again demonstrated its value. Forecasters identified the high SCP values in the region, suggesting a significant risk of strong to violent tornadoes. The warnings issued based on this information allowed people to seek shelter and prepare for the impending severe weather. The accurate forecasting and timely warnings were credited with saving numerous lives, even as the powerful tornadoes caused extensive damage.

      Limitations and Ongoing Research: While the Supercell Composite Parameter is a valuable tool in severe weather forecasting, it is not without its limitations. The SCP is designed specifically to assess the potential for supercell thunderstorm development and does not account for other types of severe weather, such as non-supercell tornadoes or severe wind events. Additionally, the SCP is based on atmospheric conditions at a specific time and location and may not capture the full evolution of a severe weather event over time.

      To address these limitations and further improve severe weather forecasting, ongoing research is focused on refining the SCP and developing new tools and techniques. Meteorologists and atmospheric scientists are working to incorporate additional variables, such as high-resolution radar data and machine learning algorithms, to enhance the accuracy and lead time of severe weather predictions.

      One area of active research is the development of probabilistic forecasting methods that provide a range of possible outcomes based on the uncertainty in the atmospheric conditions. By presenting severe weather forecasts in terms of probabilities, meteorologists can better communicate the level of risk to the public and support more informed decision-making.

      The Enhanced Fujita (EF) Scale is a system used to classify the strength of tornadoes based on the damage they cause to structures and vegetation. Developed in 2007 as an update to the original Fujita Scale, the EF Scale provides a more precise and comprehensive method for assessing tornado intensity.
      The EF Scale consists of six categories, ranging from EF0 to EF5, with EF0 being the weakest and EF5 being the strongest. Each category is defined by specific wind speed ranges and the corresponding damage expected at those wind speeds.


      EF0 (65-85 mph): These tornadoes cause light damage, such as broken tree branches, shallow rooted trees being toppled, and minor damage to chimneys or sign boards


      EF1 (86-110 mph): Moderate damage occurs, including roof surfaces being peeled off, mobile homes being pushed off foundations or overturned, and exterior doors and windows being damaged.


      EF2 (111-135 mph): Considerable damage is observed, with roofs torn off well-constructed houses, mobile homes completely destroyed, large trees snapped or uprooted, and light objects becoming projectiles.


      EF3 (136-165 mph): Severe damage happens, including entire stories of well-constructed houses being destroyed, trains overturned, and forests being heavily damaged.


      EF4 (166-200 mph): Devastating damage takes place, with well-constructed houses being leveled, structures with weak foundations blown away, and cars thrown.


      EF5 (>200 mph): Incredible damage occurs, with strong frame houses being lifted off foundations and carried considerable distances, automobile-sized missiles flying through the air, and trees being debarked.

      Storm Chasing in Canada: Tracking Nature’s Fury

      Posted on by Collective Weather

      Canada, known for its diverse landscapes and vast expanses, is also home to a unique meteorological phenomenon – severe thunderstorms and tornadoes. While storm chasing is more commonly associated with the United States, particularly in the infamous “Tornado Alley,” Canada experiences its fair share of severe weather events, attracting both professional meteorologists and amateur storm chasers.

      Meteorology Behind Canadian Storm Chasing The formation of severe thunderstorms and tornadoes in Canada is primarily influenced by the collision of contrasting air masses. During the summer months, warm, moist air from the Gulf of Mexico and the United States Great Plains often clashes with cooler, drier air from the Arctic. This collision creates instability in the atmosphere, leading to the development of powerful supercell thunderstorms.

      Additionally, Canada’s unique topography plays a role in storm formation. The prairies, with their flat, open landscapes, allow for uninterrupted wind flow and the creation of strong updrafts necessary for tornado development. The presence of the Rocky Mountains to the west also contributes to the formation of severe weather, as the mountains can help channel and intensify storm systems.

      Prime Storm Chasing Locations in Canada

      1. Southern Ontario: This region, particularly the area extending from Windsor to Toronto, experiences the highest frequency of tornadoes in Canada. The proximity to the Great Lakes and the convergence of air masses make this area a hotspot for severe weather.
      2. Alberta: Known as “Hailstorm Alley,” central and southern Alberta often experience severe thunderstorms capable of producing large hail, damaging winds, and occasional tornadoes. Cities like Calgary and Red Deer are prime locations for storm chasers.
      3. Saskatchewan: The southern portions of Saskatchewan, especially along the border with the United States, are prone to severe thunderstorms and tornadoes. The flat, open prairies provide an ideal environment for storm development.
      4. Manitoba: Similar to Saskatchewan, southern Manitoba experiences severe weather due to its location and topography. The Red River Valley, in particular, is a corridor for intense storm systems.

      Tornado Statistics by Province According to Environment and Climate Change Canada, the average number of reported tornadoes per year in each province is as follows:

      1. Ontario: 12-18
      2. Alberta: 10-15
      3. Saskatchewan: 8-12
      4. Manitoba: 6-10
      5. Quebec: 4-8
      6. New Brunswick: 1-2
      7. British Columbia: 0-1
      8. Nova Scotia: 0-1
      9. Prince Edward Island: 0-1
      10. Newfoundland and Labrador: 0-1

      It is important to note that these numbers are based on reported tornadoes and may not reflect the actual occurrence, as some tornadoes in remote areas may go undetected.

      Storm chasing in Canada is a thrilling and scientifically valuable pursuit, but it also comes with inherent risks. Chasers must be well-prepared, equipped with proper safety gear, and knowledgeable about severe weather dynamics. It is crucial to respect the power of nature and prioritize personal safety above all else.

      As climate change continues to influence weather patterns worldwide, studying severe weather events in Canada becomes increasingly important.

      Top 5 Weather Events in Canada
