An Experiment of Radar-based Quantitative Precipitation Estimate Method for Short Time Heavy Rain in Guangxi Province
摘要
Abstract
Z-I relations for short time heavy rain RQPE are defined respectively by using optimization method and regression method,based on radar CAPPI and auto weather station precipitation data in Guangxi region 2011-2013.Error analysis showed that CAPPI on 3.0 km altitude is most appropriate for RQPE.Compared with regres-sion method and fixed Z-I relation (Z =300I1.4 ),optimization method RQPE is closer to actual precipitation and is more reliable.The error of fixed Z-I relation method RQPE are serious but concentrative.The error of regression Z-I relation method RQPE are serious and emanative.关键词
