Australia's bushfires burn so intensely that they hurl smoke as far away as Chile. Here is how they created their own weather systems
In this December 30, 2019 aerial photo, wildfires rage under plumes of smoke in Bairnsdale, Australia. They have also created their own weather systems, including deadly "firestorms" that produce dry lightning and cannot be contained.Scientists are still trying to understand how firestorms are created although weather, terrain, vegetation and the characteristics of the fire itself all play a role.
"Collisions of ice particles in the very cold upper parts of these clouds cause a build-up of electrical charge, which is released by giant sparks-lightning. Having produced a thunderstorm, the cloud is now known as 'pyrocumulonimbus'."Firestorms tend to produce very little rain, so the lightning can strike the dry earth and create new fires in the surrounding area.
This handout satellite image, taken on December 31, 2019 and received from Planet Labs, Inc. on January 7, 2020, shows smoking rising into the air from bushfires near Lake Conjolia in the Australian state of New South Wales. Experts say the storms are incredibly difficult to predict because the fires themselves are difficult to predict. But some believe they are close to at least forecasting when weather conditions will make the storms possible.
