PROBLEMS OF AUSTRALIAN BUSHFIRE
- 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
- They are large, tall clouds that are dark on the bottom and usually produce rain and thunderstorms.
- 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.
