On May 22, 2015, a Conair Group float-equipped Air Tractor AT-802 fighting a fire near Cold Lake, Alberta encountered a fire whirl. The encounter resulted in a loss of control and collision with terrain, killing the pilot on board.

2021年9月2日 · Fire whirls, much like dust devils, are not uncommon on a fire when the atmosphere is unstable, and are much smaller than fire tornados. In 1978 a researcher for the National Weather...

2024年10月31日 · Fire whirls range in size from less than 1 m in diameter and velocities less than 10 m/s up to possibly 3 km in diameter and winds greater than 50 m/s. They have been observed in wildland, urban, and oil spill fires and volcanic eruptions.

2023年8月2日 · When wildfires do ignite, they can create their own weather patterns, including fire whirls. That's when a wildfire plume combines with rotating air to form a "spinning column of fire" akin to a...

In a fire whirl, rising hot air twists flames into a towering pillar. Although fire whirls in wildlands are normally small, fire whirls can grow large and destructive, forming into a burning tornado, as in the case of the 2018 Carr fire in California.

5 天之前 · Notable Fire Tornado Incidents. Carr Fire, California (2018): One of the most powerful fire tornadoes ever recorded, with winds exceeding 143 mph, equivalent to an EF3 tornado. Canberra, Australia (2003): A firestorm produced multiple fire whirls that contributed to the rapid spread of wildfires, devastating homes and wildlife.

Fire whirls, often referred to as fire tornadoes, are fascinating phenomena that occur when flames and hot gases rise rapidly, creating a rotating column of fire. These whirls can significantly ...

2023年8月1日 · Fire whirls occur when superheated air near the surface of a large fire zone rises rapidly in an air mass that also spins, much like a dust devil or whirlwind. But...

2024年1月25日 · In the most extreme urban and wildland fires, fire whirls can form, presenting significant hazards. After a brief review of our state of knowledge concerning fire whirls, two new approaches using the intensification of combustion seen in fire whirls to reduce their emissions will be covered.

Fire whirls, especially the larger ones, represent a considerable safety hazard to firefighters through increased fire intensity, spotting, erratic spread rate and direction, and wind damage. Fire whirls range in size from less than 1 m in diameter and velocities less than 10 m/s up to possibly 3 km in diameter and winds greater than 50 m/s.
