Turkey tower is a slang term for a narrow, individual towering cloud from a small cumulus cloud which develops and suddenly falls apart. Sudden development of turkey towers could signify the breaking or weakening of a capping inversion. Cumulus congestus cloud Cumulus congestus clouds, also known as towering cumulus, are a form of cumulus cloud that can be based in the low or middle height ranges. They achieve considerable vertical development in areas of deep, moist convection. They are an intermediate stage between cumulus mediocris and cumulonimbus. Cumulus congestus clouds are characteristic of
Cyclogenesis cloud. The wall cloud is a spinning layer of clouds descending from the mesocyclone. The wall cloud tends to form closer to the center of the mesocyclone. It should be noted the wall clouds do not necessarily need a mesocyclone to form and do not always rotate. As the wall cloud descends, a funnel-shaped cloud may form at its center. This is the first stage of tornado formation. The presence of a mesocyclone is believed to be a key factor in the formation of the strong tornadoes associated with severe thunderstorms. Tornadoes exist on the microscale or low end of
