| 摘 要： | 用相关分析法计算了北疆冬季降水与前期各月北半球500hPa平均高度场的相关系数，选择相关好的域计算了北疆冬季降水异常年份对应的前期相关月的500hPa距平场，结果表明当年9月欧洲脊的强弱及新疆上空急锋锋区的位置与前冬降水异常有一定的相关，6月北欧-极区冷空气的强度及12月西西伯利亚脊的位置和强弱与后冬降水异常有一定的相关。

| Abstract: | It is showed that there are some lag-correlation between the precipitation from November to December and European ridge and the position of polar frontal zone over Xinjiang in September.Also,the precipitation from January to February is correlated with cold air intensity from Noth Europe to polar region in June and the position and intensity of Siberrian ridge in December. |

| Keywords: | winter abnormal precipitation previous circulation situation correlation |
