I recently saw a great cloud show on a trip to Denver. It started with a very dramatic dark sky just before a thunderstorm and ended with these impressive Mammatus clouds. The clouds are named after the Latin word mamma meaning “udder” or “breast”. They form on the underside of various cloud types especially Cumulonimbus and are a result of reverse convection. Warm humid air falls and some of the water vapor mixes with cooler air forming hanging pouches.
