Wildfires: The ominous 'fire clouds' or 'pyrocumulonimbus' seen in France for the first time
Summary
Firefighters in southwest France are facing strong fire clouds called pyrocumulonimbus for the first time. These clouds form over large wildfires, create their own winds and lightning, and make fires harder to control. Experts link the emergence of these fire clouds to climate change, which increases heatwaves and extreme weather.Key Facts
- Pyrocumulonimbus clouds are large storm clouds created by intense wildfires.
- These clouds produce strong updrafts, their own wind, and lightning that can start new fires.
- Fire clouds are common in places like Portugal, California, and Australia, but are new to France.
- The recent fire clouds in France are linked to human-caused climate change and more frequent heatwaves.
- These clouds form when water vapor rises above a fire, condenses, and creates a towering storm cloud.
- Fire clouds make firefighting harder because they can spread embers and change wind directions suddenly.
- Weather services can predict thunderstorms but cannot pinpoint where fire clouds will form since they depend on fire locations.
- The fire in southwest France’s Gironde region changed wind direction multiple times, helped by the fire cloud’s power.
