摘　　要：用１８７３～１９９６／１９９７年资料，延长计算了东亚冬夏季风强度指数，研究了指数的年际及年代际变化的主要特征。指出该指数与我国的冬、夏季天气的年际变化、年代际变化关系密切。还指出，该指数与印度季风强度正相关，并且能解释季风的准两年振荡。The East Asian summer and winter monsoon intensity indices are constructed by using the SLP data for the period of 1873～1996/1997 and their interannual and inter decadal variabilities are analyzed. The results show that summer and winter weather/climate over China are closely related to the monsoon intensity indices and The East Asian summer monsoon intensity has a positive relationship with the Indian monsoon, and their intensities manifest quasi biennial oscillations.
