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.

            The El Reno Tornado: A Colossus on the Oklahoma Plains – May 31, 2013

            Posted on by Collective Weather

            The late afternoon of May 31, 2013, witnessed the birth of a meteorological monster on the open plains west of Oklahoma City – the El Reno tornado. This colossal twister, eventually reaching a staggering 2.6 miles wide, etched its name in history as the widest tornado ever recorded. Its immense size and erratic behavior posed a significant challenge for storm chasers and researchers, ultimately claiming the lives of three experienced storm chasers who were caught in its unpredictable path.

            The day began with a heightened sense of awareness among meteorologists and storm chasers. The Storm Prediction Center had issued a high-risk warning for severe weather, highlighting the potential for strong, long-track tornadoes across central Oklahoma. As the afternoon progressed, supercell thunderstorms began to develop, their towering structures visible from miles away. Among these storms, one particular supercell exhibited ominous signs of rotation and quickly became the focus of attention.

            At approximately 6:03 pm, the El Reno tornado touched down, initially as a relatively narrow funnel. However, it rapidly intensified and expanded, growing wider and wider as it churned across the open landscape. The tornado’s erratic movements and multiple vortices made it difficult to track and predict, posing a significant danger to those in its path.

            Caught in the Colossus: Stories of Impact and Loss

            The El Reno tornado’s unpredictable nature and immense size had a profound impact on those who encountered it, including experienced storm chasers and researchers who dedicated their lives to understanding these powerful storms.

            • TWISTEX Team: The TWISTEX (Tactical Weather Instrumented Sampling in/near Tornadoes Experiment) team, a group of researchers studying tornadoes, was caught in the path of the El Reno tornado. Their vehicle was tossed by the tornado’s winds, resulting in injuries to several team members and tragically claiming the life of renowned storm chaser Tim Samaras, his son Paul Samaras, and fellow chaser Carl Young.
            • Other Storm Chasers: Several other storm chasers had close encounters with the El Reno tornado, capturing dramatic footage of the twister’s immense size and erratic movements. Many experienced the dangers of chasing such a large and unpredictable tornado firsthand, highlighting the risks associated with this activity.
            • Record-Breaking Width: At its peak, the El Reno tornado reached a staggering width of 2.6 miles, making it the widest tornado ever recorded. This immense size is attributed to the presence of multiple vortices within the parent circulation, effectively creating a massive wedge tornado with a broad damage path. The sheer width of the tornado made it difficult to perceive its full extent from the ground, leading to challenges in tracking and warning for its path.
            • Fluctuating Intensity: The El Reno tornado exhibited rapid fluctuations in intensity, ranging from EF3 to EF5 on the Enhanced Fujita scale. This variation in strength is a characteristic of many large tornadoes and is influenced by the complex dynamics of the storm’s updraft and the inflow of air feeding the tornado. The tornado’s multiple vortices also likely contributed to its fluctuating intensity, as each subvortex could possess varying degrees of strength.
            • Damage Indicators: Despite its immense size and fluctuating intensity, the El Reno tornado’s damage path was primarily rated EF3. This is because the tornado traversed mostly rural areas with few structures to serve as damage indicators. However, the few structures that were impacted sustained significant damage, indicative of the tornado’s potential for greater destruction had it tracked through a more densely populated area.
            • Reed Timmer and the Dominator Team: Veteran storm chaser Reed Timmer and his Dominator team were in close proximity to the El Reno tornado, capturing dramatic footage of its rapid expansion and erratic movements. They experienced the tornado’s powerful winds firsthand as their armored vehicle, the Dominator, was buffeted and pushed off the road. Timmer described the experience as “the most intense moment of my storm chasing career,” highlighting the sheer power and danger of the El Reno tornado.
            • Mike Bettes and The Weather Channel Team: The Weather Channel team, led by meteorologist Mike Bettes, was also chasing the El Reno tornado. Their SUV was caught in one of the tornado’s subvortices and thrown 200 yards, resulting in injuries to the team members. Bettes later recounted the experience as a “life-changing event” that underscored the unpredictable nature of tornadoes and the importance of safety precautions when chasing storms.

            The Tri-State Tornado: A Trail of Destruction Across Three States – March 18, 1925

            Posted on by Collective Weather

            The afternoon of March 18, 1925, etched itself into the annals of American history as the deadliest tornado event the nation has ever witnessed. A single, monstrous tornado tore through portions of Missouri, Illinois, and Indiana, leaving behind a 219-mile path of devastation. In its wake, the Tri-State Tornado, as it came to be known, claimed 695 lives, injured over 2,000 people, and caused catastrophic damage to homes, businesses, and the landscape itself. The roar of the tornado was said to be audible from miles away, described by survivors as sounding like a freight train or the continuous rumble of thunder.

            Emerging in southeastern Missouri, the tornado first touched down around 1 p.m. near Ellington. Witnesses reported seeing a dark, swirling funnel cloud descend from the sky, growing in size and intensity as it moved across the countryside. The small community of Annapolis, Missouri was directly in its path, and within minutes, the town was reduced to rubble. Homes were obliterated, trees uprooted, and the local schoolhouse was completely destroyed with over 100 students inside. Miraculously, only one child lost their life due to the quick actions of the teachers who ushered the children into the basement just before the tornado struck. Sadly, 38 people lost their lives in Annapolis alone. Continuing its northeastward track, the tornado crossed the Mississippi River into southern Illinois, striking the towns of Gorham and Murphysboro. Murphysboro suffered the most significant loss of life with 234 fatalities. The business district was completely leveled, and the remains of the Murphysboro High School were scattered for miles.

            As the tornado moved into Indiana, its path widened, reaching an astonishing 2.5 miles at its maximum width. The towns of Griffin and Owensville were heavily impacted, with countless homes and businesses leveled. In Griffin, a local church was destroyed while a service was in progress, resulting in the tragic loss of 69 lives. The Tri-State Tornado finally dissipated near Petersburg, Indiana, after a horrifying 3.5-hour rampage. In total, 19 communities were directly affected, with thousands of buildings destroyed and an estimated $17 million in property damage (equivalent to over $250 million today). The aftermath resembled a war zone, with debris strewn across the landscape and survivors left in shock and despair.

            The meteorological conditions that spawned the Tri-State Tornado were a potent mix of atmospheric ingredients. A strong low-pressure system tracked across the central plains, dragging a warm front northward. To the south, warm, moist air surged from the Gulf of Mexico, while cold, dry air aloft created an unstable atmosphere. As the warm front collided with the colder air, powerful thunderstorms erupted, providing the energy needed for tornadic development.

            The specific dynamics of the storm system, including wind shear (changes in wind speed and direction with height), contributed to the tornado’s longevity and intensity. The wind shear created a horizontal rolling motion in the atmosphere, which helped to concentrate and stretch the storm’s rotation, leading to the formation of a long-lasting and powerful tornado. Additionally, the relatively flat terrain of the region offered little resistance to the twister’s path, allowing it to maintain its strength over a longer distance.

            The Tri-State Tornado remains a stark reminder of the destructive power of nature and the importance of severe weather preparedness. Its legacy has contributed to advancements in tornado research, forecasting, and warning systems, ultimately saving countless lives in the decades since this devastating event. The storm’s impact on the field of meteorology is undeniable, as it prompted further study of tornado formation and behavior, leading to improved understanding and prediction of these destructive forces.

            One of the closest comparisons in terms of path length is the Great Natchez Tornado of 1840. This devastating tornado, which struck Natchez, Mississippi and surrounding areas, carved a path estimated to be between 150 and 200 miles long. However, due to limitations in record-keeping and population density at the time, the exact number of fatalities remains uncertain, with estimates ranging from 100 to 317 deaths.

            Another notable tornado event was the 1974 Super Outbreak, which unleashed 148 tornadoes across 13 states in just 18 hours. This outbreak resulted in 330 fatalities and caused extensive damage. However, the Super Outbreak was characterized by numerous individual tornadoes, rather than a single, long-track event like the Tri-State Tornado.

            Tornado Vision: App Review

            Posted on by Collective Weather

            Tornado Vision is an app that combines three separate features to be the ultimate assistant for those who are interested to keep situational awareness of severe weather.

            For one the app uses augmented reality to display the nearest storm to you with the latest data including the chance of hail, tornado and wind as well as information about warnings and storm reports as well as direction and distance. You can click on any of these icons to get a more detailed display.

            Here you can see a tutorial of all the individual augmented reality features for a storm when using Tornado Vision.

            Tornado Vision also has filters that were tested on hundreds of low contrast tornadoes, usually those hidden in the rain that help you bring out the details.

            This tornado WAS NOT visible to the naked eye at this point but with the help of Tornado Vision is 100% visible. The last feature of Tornado Vision is the lightning trigger, at night it’s incredibly hard to see a torando except for a momentary flash of lightning, by switching to night mode you can have it freeze whenever a certain illumination point is reached, this will help you see tornadoes more easily.

            Here are videos of Tornado Vision being used around severe storms.

            The full features of TornadoVision are:

            Augmented Reality displays chance of tornado, hail (and size) and wind when looking at a storm.

            Augmented Reality displays if you are in tornado or severe thunderstorm warning.

            Augmented reality displays any Tornado or Hail reports.

            Four specially designed camera filters help bring out tornadoes hiding in the rain.

            Night mode automatically captures hidden night-time tornadoes.

            Bring up data on storm characteristics, including rotation, maximum hail size and lightning flash rate.

            Bring up environmental data like storm relative helicity, CAPE and bulk wind.
