要約

The differential Doppler velocity is one of the parameters that combines in itself both the Doppler and polarization measurements while scanning the meteorological precipitation with the help of a Doppler polarimetric radar. The Doppler measurements allow to get information about dynamic processes occurring in precipitation (raindrop velocity) and the polarimetric measurements allow to get an information about the shape and orientation of hydrometeors. When turbulence occurs, the raindrops are involved into motion and change their velocity and orientation. The investigation results for the dependence of the differential Doppler velocity upon the turbulence intensity are represented in this paper. Relationship between these parameters is shown both theoretically with the help of the developed model and practically after processing of the data obtained from the Doppler polarimetric radar.
