Naval Research Laboratory, at a news conference on pyroCb research, hosted Friday at the annual fall meeting of the American Geophysical Union. “So now we’re at a whole new level of pyroCb activity.”Huge pyroCb events are at the cutting edge of wildfire research. It’s also helping scientists better understand the way wildfire smoke changes a cloud’s properties and what that might mean for local weather patterns. A big pyroCb event can generate smoke plumes that spin as they move through the stratosphere—it happened with the Australian New Year’s event. Wildfire smoke plumes involve a lot of complicated, fine-scale physics that often are challenging to simulate.
