Abstract :
The variance of the radial velocity in a cloud radar´s signature is an underused parameter. The parameter represents a combination of the effects of convective turbulence and mechanical mixing from wind shear. It´s usefulness in deciphering laminar, sheared, and turbulent mountain-influenced airflows within clouds is demonstrated in this paper
