Real Time Divergence Measurement from Single Doppler Radar.

Abstract

Mesoscale convergence is throught to influence development of convective storms. Convergence can be measured with a single Doppler radar if the wind field is approximately spatially linear. The algorithm for measuring convergence from radial velocities is presented. The algorithm is feasible for real time application to two elevation angles of a tilt sequence of five or more elevation angles. This convergence measurement technique is applied to widespread convective precipitation in central Oklahoma on April 9, 1978. Analysis results and the suitability of the spatial linearity assumption are discussed. (Author)
