摘要：

利用10aECMWF风应力资料强迫LASG/IAPL30T63大洋环流模式,模拟分析了印度洋海温变化的基本特征,重点分析了1982年印度洋偶极子事件。模式很好地模拟印度洋的季节变化;模拟的印度洋偶极子指数与实际资料大体上相似,但并非一一对应,且存在2~4月滞后,振幅也小于资料分析的结果;对1982年印度洋偶极子事件做个例分析,研究其发生、发展以及消亡的基本特征。

Using ten years’ wind stress data of ECMWF, the OGCM of LASG/IAP is drived,then basic features of temperature variation have been simulated and analysed for the IndianOcean, especially the event of Indian Ocean Dipole in 1982. The seasonal variation ofIndian Ocean is modeled desirably. And the simulated index for Indian Ocean Dipole issimilar to real data, but the phase is delayed to two and four months and the amplitudeis smaller than results of data analyses. In a word, we have done the case analyses forthe event of Indian Ocean Dipole in 1982 whose basic features of generation、developmentand dissipation are studied.
