Universal Fire Shape and Whirls
Listed in NASA Earthdata CMR
Explore the basis of the universal fire shape as well as twirl and burst behavior.
Description
In this wildfire simulation, as the fire spreads, it evolves into a shape well-known to fire managers. The "head" is the leading edge of the fire where the heat is focused.
Along the side are two "flanks", where the winds blow parallel to the edge of the fire. The "Back" is the slowest moving part of the fire and creeps against the wind. In addition, an animation of the vertical vorticity (rotation of air) shows the presence of fire whirls.

Wildfires can contain fire whirls of greatly varied intensity, duration and size - from a few meters in diameter, to where the entire smoke-filled updraft (perhaps 1 km wide) is rotating. Most are small, but they have been known to break off trees more than a meter in diameter.
