The common factor in all supercells is the deep, persistent mesocyclone, of the storms precipitation characteristics.
Positive shear estimates the mean shear of a given layer of a hodograph.
SRH takes storm motion into account. Strength of the storm inflow is a critical factor in the development of a strongly rotating updraft. During the cooler months , wind environments that favor mesocyclone development are common and widespread, however, instability is usually infrequent and relatively low. In the warmer months , moderate to high values of instability occur while sufficient wind environments are infrequent. Relatively high LFCs Lifted Index is not representative due to a lack of low level moisture Large hail is the main threat, but narrow rope like tornadoes can occur 3.
