| 摘 要： | 应用局地型相似系数(local pattem analogue coefficient，LPAC)图及较差图分析了运城市夏季(6月～8月)降水量与前期北半球500hPa位势高度场的相关性，并尝试使用LPAC图显示的关键区制作夏季降水预报，效果较好。

| Abstract: | Correlativity between summer (June -August) precipitation and earlier potential height field at 500hpa of Northern Hemisphere was analyzed by using the local pattern analogue coefficient (LPAC) and the differance chart, Key area shown in LPAC chart were attempted for precipitation forecast in summer and better effect was gotten. |
