Horizontal Divergence and Vertical Velocity Retrievals from Doppler Radar and Wind Profiler Observations
Abstract
Vertical motion profiles can be diagnosed with the mass continuity equation using horizontal divergence fields derived from various single-Doppler radar techniques such as EVAD (extended velocity-azimuth display), CEVAD (concurrent extended velocity-azimuth display), and VVP (volume velocity processing). These methods allow for the retrieval of mesoscale air motions in precipitating regions when the wind field is relatively homogeneous. In contrast, VHF wind profiler data can provide a direct measurement of vertical motion, albeit across a much smaller domain compared to the single-Doppler radar techniques. In this study, we compare horizontal divergence and vertical motion patterns derived from the various single-Doppler methods with those obtained from VHF profiler data.
