摘要
Abstract
Based on the data of monthly-mean sea surface temperature (SST), outgoing longwave radiation (OLR) and the 1000 hPa zonal wind velocity from NCEP/NCAR reanalysis data of 1979～1998, the SST anomalies of the tropical Indian Ocean and the Pacific Ocean and the character of correlated circulation have been comprehensively analyzed and studied. It is found that there are interdecadual differences in the intensity of dipole mode, which may represent a characteristic internal mode of the Indian Ocean climate system. In the 1980s, the dipole mode of the Indian Ocean SST is weaker, while in the 1990s it is stronger. There is interactions between the tropical Indian Ocean and the Pacific Ocean systems. In the 1990s, the SST anomaly in the tropical Indian is mainly the response of
the Pacific ENSO, while the abnormality of the Pacific ENSO in the 1990s is, to a certain extent, the result of the active Indian Ocean dipole mode. From the angle of observed data diagnosis, the possible cause of the poor prediction skills of ENSO in ZC coupled models of the 1990s has been proposed.关键词
