Verification of Precipitation Forecasts for 1993 from Limited-area Analysis Forecast System

Synoptic and statistic methods are employed to verify the precipitation forecasts for 1993 from LAFS. The results show that the forecasts for most main precipitation events are successful; the accuracies of moderate and heavy rain predictions are higher than those of torrential rain ones: the accuracy of precipitation predictions for South China is higher than that over the rest parts of China, unfortunately, and the lowest for Qinghai –Tibet Plateau. It is the defects in LAFS that the area of precipitation forecasts is too large.
