From fire to cloud
A fire can create its own weather.
Stan Goldade took this picture 20 miles north of Breckenridge, Minnesota, today. It appeared someone was burning a CRP field.
The smoke plume shot straight up forming a cloud. How can fire turn to cloud?
First of all, it is a very calm day so there is very little wind shear to break up the smoke plume. Secondly, air cools as it rises, even if the air is hot and coming off an open flame.
Rising air undergoes a reduction in density as the air pressure around lowers with increasing altitude. Eventually, if not sheared away by winds, the column of air reaches the point where it has cooled enough for moisture to condense into water drops. In other words, the humidity turns to cloud.
