About 15 GCMs (GFDL1, GISS, LLNL, MPI, OSU, UKMOL, UKMOH, GCMs90-92, GFDL2, NCAR, OPYC, LSG, HADL, GCMs95) obtained from the IPCC WG 1 1990, 1992 and 1995 reports have been chosen to examine the impacts of global warming, on the climate chance over East Asia. Although the models scenarios of the human activities were different for the different GCMs, the climate change over East Asia (70E-140E, 15N-60N) for tile doubled CO{sub 2} as simulated by about 15 GCMs have been analysed. The Simulations shown that the temperature might increased by about 0.5 - 1.5 C over East Asia, especially in winter and northwestern parts of East Asia. The precipitation might increase in northwestern and northeastern parts of East Asia and decrease in the central part of East Asia. The evaluations and assessments of the GCMs over East Asia have indicated that the GCMs have the abilities to simulate the climate change over East Asia, especially for the temperature and the winter season. There are some uncertainties for the simulations to compare with the observations, especially for tile precipitation and tile summer season.
