摘要：

Multiparameter radar measurements were made during a heavy rainfall event accompanied by hail in Colorado. Rainfall rates R and accumulation Sigma for this event were estimated using S-band specific differential phase K-DP, reflectivity factor Z(H), and X-band specific attenuation A(H3) These estimates were compared with measurements from a ground-based rain gauge. Both R-KDP and R-A(H3) relations were in good agreement with the rain gauge data, that is, less than 10% difference in the rainfall accumulations. The R-Z relation produced similar results only when Z(H) was truncated at 55 dBZ. This study demonstrates the potential of K-DP for estimating rainfall rates in severe storms that may have rain-hail mixtures.
