| 摘 要： | By using the simulation results of an AGCM, which had been run from 1945 to 1993 forced by
COADS SST, the interdecadal variability of the model atmosphere was investigated and compared with that of
NCEP reanalysis data. It was found that, interdecadal variability exists significantly in both the tropical Pacific
wind fields and the mid-high latitude atmospheric circulation of the model atmosphere. The tendency of time
variation and spatial distributions of the interdecadal variability of the model atmosphere are basically consistent with observation. Relative to the mid-high latitude atmospheric circulation, the simulation of tropical Pacific wind is more satisfying, which suggests that anomalous variation of SST is still the main factor for the
interdecadal variability of tropical Pacific wind. It might have more significant influence on the tropical wind
than on the mid-high latitude atmosphere. However, there is still obvious difference between the simulation and
observation. They could be attributed to both the simulation capability of the model and absence of other factors
in the model which are important for the interdecadal climate variation.
