On the analysis of single-Doppler radar data.

Abstract

The procedures currently employed to retrieve vector wind information from single-Doppler radar observations are reviewed briefly. In particular, those procedures implying a linearity hypothesis for the wind field are shown to be particular cases of a method termed VVP (Volume Velocity Processing). This method, which makes full use of radar velocity data filling a volume, is first tested on simulated observations in order to assess its accuracy, then applied to actual data and shown to yield unbiased parameters of the horizontal vector wind field, as well as an estimate of the hydrometeor fall velocity and several control parameters. - Authors
