A pyrocumulus cloud, sometimes nicknamed a "fire cloud," is a cumuliform cloud produced from the intensive heating of air caused by a fire.

On September 11th, as I was flying from Los Angeles to Oakland, I took this picture of the pyrocumulus cloud created from the uncontrolled "Rough Fire" burning east of Fresno, California (see map below). The flight was at around 30,000 feet.

As of September 14, 3pm (Pacific), the Rough Fire is the largest wildfire burning in California, has destroyed approximately 140,000 acres, and is only 40 percent contained.
