Convection


This photo was shot at sunset in western Iowa on April 15, 2006, at the end of a long, frustrating day of chasing. There were tornadoes that day, but I missed them.

This is an extreme zoom-in on "convection" of a storm about 15 miles away. Convection are those pillowy, cauliflower-like clouds you see rising out of a storm. They're caused as massive, turbulent updrafts loft moisture in high into the sky where it condenses into clouds -- and eventually rain. As the moisture condenses, it releases heat, which drives even more moisture even further up.
