| 摘 要： | 应用天气学和统计学方法对1993年LAFS数值降水预报产品进行检验。结果表明:多数主要降水过程预报较好；全年降水10mm级和25mm级降水预报准确率高于50mm级降水的准确率；南方降水预报水平比其它地区高，高原地区最差；降水预报范围过大是LAFS的一大弱点。

| Abstract: | Synoptic and statistic methods are employed to verify the precipitation for ecasts for1993 from LAFS.The results show that the forecasts for most main precipitation eventsare successful;the accuracies of moderate and hpavy rain predictions are higher thanthose of torrential rain ones;the acciiracy of precipitation predictions for South China ishigher 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 toolarge. |
