摘　　要：利用SST资料对西太平洋暖池海温异常年进行划分,通过对异常年850 hPa、200 hPa矢量风场进行合成分析后发现:在西太平洋暖池夏季暖异常年,副热带夏季风和副热带季风经圈环流得到加强,热带西南季风得到削弱;在暖池夏季冷异常年,热带西南季风和热带季风经圈环流得到了加强,副热带夏季风得到削弱。在暖池冬季暖异常年,东亚冬季风、东亚和印尼-北澳冬季风(北半球)经向垂直环流得到削弱;在暖池冬季冷异常年,东亚冬季风、东亚和印尼-北澳冬季风(北半球)经向垂直环流得到加强。The SST anomalies years in the western Pacific warm pool are classified based on the SST data, then a composite analysis is applied to the 850 hPa and 200 hPa vector wind field. It is found that during the summer warm anomalous year of the western Pacific warm pool, the subtropical summer mon- soon and subtropical monsoon meridional circulation are strengthened, while the tropical southwestern monsoon is weakened. During the summer cold anomalous year of the warm pool, the tropical southwest- ern monsoon and tropical monsoon meridional circulation are strengthened, while the subtropical summer monsoon is weakened. During the winter warm anomalous year of the warm pool, the winter monsoon in the East Asia, and meridional vertical circulation in the East Asia and Indonesia-Australian winter mon- soon （the northern hemisphere） are weakened. The situation in winter cold anomalous year of the warm pool is opposite.
