Eastern Asian Winter Monsoon Anomaly and Variation of Global CirculationPart. I: A Comparison Study on Strong and Weak Winter Monsoon
东亚冬季风异常与全球大气环流变化 I. 强弱冬季风影响的对比研究

By using the ECMWF data, a strong winter monsoon year (1986) and a weak one (1980) are chosen for case study, and their difference of many characteristics both on the local and global circulations is compared The main results are as follows The East Asian Winter Monsoon is an important component of the global circulation and its anomaly is relevant to the variation of global circulation especially to the tropical circulations Winter monsoon anomaly not only results in the difference of the circulation in winter, but also affects the circulation and weather in the following seasons Most important is the persistence of the anomalous circulation and the characteristics caused by the anomalous winter monsoon over tropical region, including the convection, Hadley and Walker cells, which maintains from winter to summer
