Pyrocumulonimbus (pyroCB) storms are feared due to the violent and unpredictable conditions they create on the groundScientists fear surge in supersized bushfires that create their own violent thunderstormsScientists fear climate change will drive a surge in the number of supersized and dangerous bushfires that become coupled with the atmosphere and create their own violent thunderstorms. PyroCB storms are feared by firefighters for the violent and unpredictable conditions they create on the ground. Research scientist Rick McRae, who is the custodian of a register of Australian pyroCB events, said 2019 was a “standout year”. Dr Andrew Dowdy, a meteorologist at the Bureau of Meteorology, has published several studies on pyroCB fires and their underlying conditions. “What we know about pyroCB conditions is summarised as ‘hot, dry, windy’,” he said.
