The INFOCA Plan has confirmed a few minutes ago that it has removed a large part of its ground personnel from the fire area, due to the existence of a ‘pyrocumulus’ or cloud of fire. It is a large cloud formed by smoke and particles from the fire, which can represent a risk to ground troops.
The pyrocumulus they are the great hidden danger of a fire. Is about smoke that transforms into clouds and that it can end in destructive winds and thunderstorms that eventually ignite new fires.
How are they formed? The intense heat source from the fire evaporates all the water stored by trees and plants. That vapor mixes with the plume of smoke and rises with currents of hot air that the fire has created. When the evaporated water reaches colder areas, it condenses, forming a cloud.
