Radar Radial Velocity Variance Measurements to Decipher Mountain-Influenced Kelvin-Helmholtz Waves, Slope Flows, and Rotors

摘要

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.
