MEDFORD, Calif., Aug. 7 (UPI) -- Wildfires continue to burn throughout California. In the last few days, more than 100,000 acres of vegetation in Northern California has already been scorched as 80 percent of state suffers through deep drought. The conditions make for tension on the ground but dramatic pictures in the air.
This week, an F-15C fighter jet with Oregon Air National Guard captured several stunning images of smoke rising from Northern California fires and forming what are called fire clouds, or scientifically speaking, pyrocumulus clouds. They form the same way regular cumulus clouds do: warm air rises and condenses as it collides with cool air above.
