"WebThe downdraft is usually due to a descending reflectivity core (precipitative loading), or water phase changes, such as melting and evaporation. Inresponse to an accelerating downdraft, the radius of the rotating region decreases while its axis lengthens [c]. Because of the conservation of angular momentum, the region will rotate even faster. 2. " - Descending reflectivity core
