摘　　要：研究了近１１０ａ北半球冬季６个主要大气活动中心的长期变化，检测其突变年份，划分了各自的阶段性。同时分析了大气活动中心与中国气候的关系，发现西伯利亚高压强度与中国冬季气温存在明显的负相关，北太平洋高压强度与中国冬季降水有较好的正相关。By investigating long term change and periodic characteristics of six principal atmospheric active centers in the northern winter during recent 100 years,it was found that three climate abrupt changes in the 1920s,middle 1940s,middle and late 1970s respectively.Correlation analyses shown that the winter temperature in China during the past 100 years were closely negatively related to the intensity of Siberian high and better postive correlation were observed between winter rainfall and the intensity of North Pacific high.
