VORTEX SIGNATURE RECOGNITION BY DOUPLER RADAR

Abstract

Doppler radar offers a possibility for investigating the flow of air within a storm. A single Doppler radar can measure only the component of precipitation motion along the radar beam. Three radars would be required for the unambiguous definition of the vector wind field within the volume. The intent of the discussion is a specification of conditions in which a vortex, or center of vorticity, may be identified from the radial velocity field provided by just one Doppler radar.
