Dust devils

Our latest podcast with Matt Senior and Jesse Williams is on dust devils. The Scientific American describes dust devils as small, rotating columns of air that we can see because of the dust and debris they pick up from the ground, resulting from a mini-weather system that occurs when one piece of ground heats up faster than the ground surrounding it on a hot, calm, dry day. They are also defined as heated thermal sources that should have been triggered but have become super heated, so that when they do release they do so with a surprising vehemence. Extremely dangerous near the ground, expert pilots do use them in competitions and during cross-country flying. In this podcast we talk about the dangers, safety, some tips and just how beautiful they are.
