Comparison of the Present-Day Climate Simulation over Asia in Selected Coupled Atmosphere-Ocean Global Climate Models

[摘要] This paper summarizes the findings of an analysis undertaken to evaluate the performance of a range of A-O GCMs in terms of the simulation of broad scale patterns of present-day climatology over Asia, and its six sub-regions. The outputs generated in transient control and anomaly experiments with the seven A-O GCMs compiled at the Data Distribution Centres in Hamburg and Norwich (set up by the Intergovernmental Panel on Climate Change) have been used in this study. The study suggests that the HadCM2, the ECHAM4, the CSIRO and the CCSR models exhibit some skill in reproducing the observed present-day surface climatic elements over the Asian continent. However, most A-O GCMs considered here have limitations in the simulation of present-day regional climatology.
