gate-to-gate azimuthal shear

Marked difference in Doppler velocity values at azimuthally adjacent range gates indicating the presence of the radial component of vorticity. Vorticity may be due to the presence of a tornado-sized vortex (tornadic vortex signature) or it may simply be caused by wind shear across a discontinuity boundary.
