The bushfires in Australia are now so big that they are generating their own weather system that can-Spark new fires,Conjure fire tornadoes and Make fighting existing fires much more challenging
CUMULONIMBUS CLOUDS
They are large, tall clouds that are dark on the bottom and usually produce rain and thunderstorms.
PYROCUMULONIMBUS CLOUDS
The rising heat from the intense bushfires creates massive, powerful clouds called pyrocumulonimbus.
These are also called “fire clouds” Created when fires loft enough heat and moisture into the atmosphere.
They are a combination of-Regular thunderstorm + The explosive heat source from the fire
If powerful enough, a pyrocumulonimbus storm can generate a fire tornado.
Happened during the Canberra bushfires in 2003.
CONCERNS DUE TO PYRO CUMULONIMBUS CLOUDS
Scientists worry that “pyroCbs” are on the rise around the world.
It is driven by warmer temperatures and more intense fires.
Their plumes are so strong that they can even shoot smoke into the stratosphere, 6 to 30 miles above the Earth’s surface.
