This study introduces a new dynamical quantity, shear gradient vorticity （SGV）, which is defined as vertical wind shear multiplying the horizontal component of vorticity gradient, aiming to diagnose heavy precipitation induced by some strong convective weather systems. The vorticity gradient compone...
