利用中国科学院大气物理研究所发展的热带太平洋环流模式（ＯＧＣＭ）和海－气耦合模式（ＣＧＣＭ）分别就冬半年东亚冬季风异常对赤道太平洋的作用进行了数值模拟研究。结果清楚地表明，无论在ＯＧＣＭ中还是在ＣＧＣＭ中，持续的冬季风强异常将引起赤道中东太平洋海表水温（ＳＳＴ）的明显正异常，其分布类似观测到的ＥｌＮｉｎｏ事件；而持续的冬季风弱异常将引起赤道中东太平洋ＳＳＴ的明显负异常，其分布十分类似观测到的ＬａＮｉｎａ事件。因此，数值模拟进一步证实了我们过去从资料诊断和理论分析中得到的结论，即东亚冬季风异常是激发产生ＥＮＳＯ的重要机制。对模式资料的分析还清楚表明，异常东亚冬季风将激发异常海洋Ｋｅｌｖｉｎ波和使热带大气季节内振荡出现强异常，它们是激发ＥＮＳＯ的重要物理因素，这与观测资料的分析结果相一致。
The effects of the East Asian winter monsoon anomaly on the equatorial Pacific during the winter and winter are numerically simulated by using the OGCM and CGCM developed by Institute of Atmospheric Physics, Chinese Academy of Sciences. The results clearly show that, in OGCM and CGCM, the persistently strong winter monsoon will cause a significant positive anomaly of SST over the equatorial Middle East Pacific, and the distribution is similar to the observed El Niño event. However, the persistent winter monsoon Weak anomaly will cause a significant negative anomaly in the SST in the equatorial central and eastern Pacific, and its distribution is very similar to the observed LaNina event. Therefore, the numerical simulation further confirms the conclusion we obtained from data diagnosis and theoretical analysis in the past that the East Asian winter monsoon anomaly is an important mechanism that stimulates the generation of ENSO. Analysis of the model data also clearly shows that anomalous East Asian winter monsoon will excite abnormal oceanic Kelvin waves and cause strong anomalies in the tropical atmospheric seasons, which are important physical factors for stimulating ENSO, which is consistent with the analysis results of the observed data.
