Fire whirlwinds have received little attention WebSep 9, 1999 · Credit: United States Marine Corps. A fire whirl is essentially a tornado of fire that can form in a wildfire. Fire whirls form because of temperature contrasts between the fire itself and its cooler surroundings (which haven't been burned yet). The resulting temperature gradients can be very large and create large pressure gradients, complete ...
