CLIMATOLOGICAL ASSESSMENT ON BASIC SIMULATED RESULTS OF GISS ATMOSPHERE-OCEAN COUPLED MODEL

GISS Atmosphere-Ocean coupled model is briefly described. Some simulation is conducted by using the model to judge its ability of climate simulation especially for Asian region. The results show that the simulated climatology of atmosphere over Asian region and ocean is close to the observation, which indicates that the model can be used for the study of climate change. Due to its coarse resolution and low requirement on computer resource, it is easy to run on the middle or small scale computer. Some defects of the model is also discussed, which need to be improved such as low surface temperature simulated in Asian region, high sea temperature, high rainfall on the south side of the Qinghai-Xizang Plateau and low precipitation in North China in Summer and so on.
