Several fires in California are creating their own localized weather systems that affect the wildfires behavior in unpredictable and dangerous ways.
Large, hot wildfires can change the local atmosphere so much that they begin to create storm clouds and wind gusts. Pyrocumulus clouds have formed towering pillars above several of the largest fires in Northern California. The clouds are composed of the water vapor from burning foliage that has risen on the fire’s heat and attached to smoke particles in the air, CNN reports.
The fires’ miniature wind gusts push the flames in unpredictable ways, complicating firefighters’ strategy of fighting it and making the fire much more dangerous to surrounding communities. The pyrocumulus clouds also behave similar to storm clouds and can create their own thunder and lightning.
“We are seeing more destructive, larger fires burning at rates that we have historically never seen,” Cal Fire regional battalion chief Jonathan Cox told CNN.
