PRELIMINARY RESEARCH FOR METHOD OF HAIL DETECTION WITH C BAND DUAL LINEAR POLARIZATION RADAR

The hail signal HDR for dual linear polarization radar has been introduced depending on the rain drop size distributions data and scattering functions for rain drops. Based on the radar data and hail reports on the ground, we have analysed the ZDR distribution rule in the CAPPI radar data, and the relations between HDR and the hail informations on the ground. The preliminary results have showed that hail detection with HDR is satisfactory. This work is applied valuable to cloud physics study and hail modification.
