Summertime daily precipitation statistics over East China in CFSv2
In this study, summertime daily precipitation statistics from the CFSv2 reforecasts were evaluated over East China. The daily precipitation statistics considered included the number of wet days, precipitation intensity (represented mean precipitation), and four extreme precipitation indices. Simulations of the climatological daily precipitation statistics by CFSv2 have been examined. The most significant bias in CFSv2 is that it produces excessive consecutive light and moderate precipitation but misses most short-duration heavy and extreme precipitation events over South and Northeast China, which further limits the simula...
