摘　　要：基于“部分通量订正”同步耦合方案,将中国科学院大气物理研究所发展的九层大气环流格点模式与十四层热带太平洋环流模式耦合并成功积分40年。结果表明,模式没有明显的“气候漂移”现象,同时模式能模拟出与未耦合的海气模式接近的气候平均态及其季节变化,及与观测接近的年际气候变率。这种年际变率在热带太平洋地区表现为类似于ENSO事件的时空分布特征。A nine-layer grid atmospheric general circulation model is coupled to a fourteen-layer tropical Pacific general circulation model with a synchronously coupling scheme, called ‘partly flux anomaly correction＇. A forty-year integration of the coupled model shows that there is no obvious ‘climate drift＇ in it, and the CGCM is fairly successful in keeping a reasonable pattern of the mean state and annual cycle. Also, the coupled model can simulate interannual variability of sea surface temperature in the tropical region. This kind of interannual variability is similar to observed ENSO.
