A Precipitation Forecast Score Based on Potential Impact by Liujie PAN, Hongfang ZHANG, Chunjuan QI, Shan LU, Lili DU

“…In traditional contingency tables， the hit and false alarm events are given equal weights when calculating the precipitation TS score.The weight of missed precipitation events with different amounts that satisfy the threshold conditions is also the same.At the same time， the frequency calculation method for hit events of different precipitation amounts within the threshold range is also the same.However， these methods lack precision in the verification of high-resolution grid precipitation forecasts.In fact， the impact of differences in observed precipitation values， even when predictions hit the threshold， may be completely different.Additionally， the impact of differences in the forecasting and observation of precipitation values in missed precipitation events may also vary greatly.The article proposes a precipitation impact forecast score based on the comprehensive consideration of precipitation hit rate， missed alarm ratio， and precipitation amount."…”
