In this paper, the interannual variability simulated by the coupled ocean-atmosphere general circulation modelof the institute of Atmospheric Physics (IAP CGCM) in 40 year integrations is analyzed, and compared with that bythe corresponding IAP AGCM which uses the climatic sea surface temperature as the boundary condition in 25 *** mean climatic states of January and July simulated by IAP CGCM are in good agreement with that by IAPAGCM, i.e., no serious 'climate drift' occurs in the CGCM simulation. A comparison of the results from AGCM andCGCM indicates that the standard deviation of the monthly averaged sea level pressure simulated by IAP CGCM ismuch greater than that by IAP AGCM in tropical region. In addition, both Southern Oscillation (SO) and NorthAtlantic Oscillation (NAO) can be found in the CGCM simulation for January, but these two oscillations do not existin the AGCM *** interannual variability of climate may be classified into two typest one is the variation of the annual mean,another is the variation of the annual amplitude. The ocean-atmosphere interaction mainly increases the first type ofvariability. By means of the rotated EOF, the most important patterns corresponding to the two types of interannualvariability are found to have different spatial and temporal characteristics.

East Asian summer monsoon simulated by a coupled ocean-atmosphere general circulation model developed in the Institute of Atmospheric Physics (IAP CGCM) is analyzed. The precipitation, low-level streamline field, sea level pressure, low-level temperature and mixing ratio are compared with the observed ones respectively. The results show that IAP CGCM can simulate most features of summer monsoon circulation, but it still has some important systematic errors. The simulated Somali jet tends to be much weak and lies too far south. The cross-equatorial flows between 120 o E and dateline are also too weaker in the model than those in reality, while the South Asia monsoon low is stronger than that in the observation and reaches further east. At the same time, the subtropical high in the western Pacific extends too far west and north. Accompanied by these deviations in tropical and subtropical zones, the westerly troughs in the middle and high latitudes affect further southerly regions in China than those observed. All these deficiencies in simulating summer monsoon circulation result in the errors in modelled precipitation in East Asia, which include the underestimation of precipitation over East Asia in summer, the premature emergence of maximum precipitation and the further southerly rainfall belt in East Asia than the observed one. So the most obvious drawbeck of the model is the apparent underestimation of Meiyu frontal rainfall.
