🔥 How Wildfires Make Their Own Weather

What you’ll learn

1. Heat makes a moving atmosphereExplain how wildfire heat creates buoyant updrafts, inflow, and plume-dominated behavior.A large fire acts as a temporary atmospheric engine, coupling combustion to rising air and local circulation.
2. From smoke column to fire cloudTrace the transition from smoke plume to pyrocumulus and pyrocumulonimbus.Moisture, cooling, condensation, and latent heat can turn a rising plume into a fire-generated cloud or thunderstorm.
3. Weather feeds the fire backDescribe how fire-generated winds, lightning, rain, and downdrafts can alter fire behavior.The weather a wildfire creates can feed back into its spread, producing both hazards and occasional suppression.
4. A larger atmospheric footprintConnect pyroCb development with smoke transport into the stratosphere and atmospheric observation.Extreme fire clouds can carry smoke far above the surface, linking local fire behavior to regional and planetary atmospheric science.
