| 摘 要： | 利用19555-1994年多种不同类型青藏高原积雪资料的综合再分析结果，通过分析青藏高原雪盖异常年冬季和初夏北半球大气环流特征，及北半球大气环流与福建雨季降水的遥相关，讨论高原雪盖异常反馈影响大气环流，进而导致福建雨季旱涝的可能途径，为在福建雨季旱涝预测中应用积雪因子提供一定的物理基础。

| Abstract: | By using 1955-1994 snow cover data on the Tibetan Plateau, the winter and early summer circulation characteristics in the abnormal years of snow cover over the Plateau and the teleconnection between the Northern Hemispheric 500hPa height and the rainy season rainfall in Fujian are analysed.And the influence of abnormal snow covers on the Northern Hemispheric circulation and further influence of the abnormal circulation on floods/droughts in rainy season in Fujian are discussed.Therefore,this paper provides a physical base for the application of snow cover in forecast. |

| Keywords: | abnormal snow cover atmospheric circulation flood/drought during rainy season |
