Summary

The IAP two-level atmospheric general circulation model was coupled to a 60-m-deep mixed layer ocean model and a zero-layer thermodynamic model to simulate the climatic effects induced by a doubling of carbon dioxide concentration in the atmosphere. The global surface temperature increase is 1.75 deg C when carbon dioxide is doubled. This value is lower than most of other results in the world, such as those of GFDL, NCAR, UKMO, GISS and OSU models. There are large regional and seasonal differences in the climatic change. Great warming is found in the Northern Hemisphere's high-latitude region and the Antartica; and the warming in the land areas is greater than in ocean areas, while the precipitation increases in high latitudes and tropical regions but decreases in subtropical regions. In both hemispheres, the warming is greater in winter than in other seasons. As for the changes in China, the authors find that the precipitation in southwestern and northern China greatly decreases in summer but increases in winter.
