CAPE*SHEAR is one of the many thunderstorm parameters, it is combination of CAPE (Convection available potential energy) and wind shear. It is computed according to: square root(2*SBCAPE) * wind shear(0-6 km). It is targeted at forecasting organized thunderstorms, such as supercell. The deep-layer wind shear helps to organise convection (represented by CAPE) into long-lived cells. High values of CAPE*SHEAR (above 700) may indicate good condition for development of severe storms.
