AN INVESTIGATION OF PRECIPITATION ATTENUATION AND ITS APPLICATION IN A DUAL-FREQUENCY RADAR MORPHOLOGY OF SUBTROPICAL PRECIPITATION

摘要

An indication of the magnitude of precipitation attenuation may be obtained by observation of a single, convective, precipitation echo with a dual-frequency radar system. The applicability of this attenuation in the study of convective liquid precipitation is in vest gated. The problem of forward scattering by both solid and liquid precipitation is examined. For small, liquid-water drops, The amount of forward scattered energy is insignificant;however, for large ice particles, forward scattering becomes important.
