| 摘 要： | In this paper,experiment results about East Asia climate from five CGCMs are described.Theability of the models to simulate present climate and the simulated response to increased carbon dioxideare both covered.The results indicate that all models show substantial changes in climate whencarbon dioxide concentrations are doubled.In particular,the strong surface warming at high latitudesin winter and the significant increase of summer precipitation in the monsoon area are produced by allmodels.Regional evaluation results show that these five CGCMs are particularly good in simulatingspatial distribution of present climate.The main characteristics of the seasonal mean H500,SAT,MSLP field can be simulated by most CGCMs.But there are significant systematic errors in SAT,MSLP,HS00 fields in most models.On the whole,DKRZ OPYC is the best in simulating the presentclimate in East Asia.
