Global warming simulation for IPCC AR4 has been conducted by using the high-resolution climate model, which was developed last year (Sumi, 2003). Various simulations are conducted following IPCC guidance and these results are submitted to IPCC Data Center. Warming of the global averaged surface temperature is consistent to the previous estimate. However, regional climate change in the East Asia is obtained. That is, the subtropical High south of Japan and the Ohotuku High is intensified and precipitation associated with the Baiu-front is increased. Hot summer day is 3 times increased. Snow accumu-lation in winter along the Japan Sea is decreased. New information about the Kuroshio is firstly obtained, that is, the location of the Kuroshio separation from Japan is unchanged but the intensity of current is increased. This is due to the intensification of the Aleutian Low. Compared with the medium resolution model results, a large difference in SST is noted.
