France Records Its First-Ever Pyrocumulonimbus Cloud Amid Record-Smashing Fires
It’s a sign of the intensity of the blazes burning—and how climate change is upping the odds that they appear.A wave of fires has swept over France and Spain, sending hundreds of thousands fleeing. To form a fire cloud—what meteorologists call a pyrocumulonimbus or the even more metal-sounding cumulonimbus flammagenitus—you first need heat, which fires have in spades.But just as important are dry conditions near the ground and cool, relatively moist conditions aloft in the atmosphere. Instead, these towering fire clouds can unleash lightning strikes that can start more fires and generate powerful downdrafts that reach the ground to fan flames further.
