What Is a Fire Cloud and How Are They Making Europe's Wildfires More Dangerous?

Ferocious wildfires in France and Spain have prompted the evacuation of hundreds of thousands of people, as firefighters battle against changing winds to keep the blazes under control. An added difficulty has developed in France thanks to the emergence of a rare meteorological phenomenon—a pyrocumulonimbus, more commonly known as a "fire cloud." Officials in the badly-impacted Gironde region, near Bordeaux, confirmed the formation of what is understood to be France’s first-ever reported fire cloud over the weekend.
