AB: The impact of the global warming climate on rainfall-systems has been one of the greatest interests in the global climate, the regional climate and cloud physics for a long time. Therefore we have carried out numerical simulations with the non-hydrostatic regional climate model which has been developed on the basis of Japan Meteorological Agency Non-Hydrostatic Model in order to reveal the change/modification of rainfall-systems around the East Asia during the Baiu season under the global warming climate as well as that in present climate. A semi-cloud resolving model with a horizontal grid of 5 km is nested in Global Climate Model (GCM) which has a horizontal grid of 20 km during 21st May to 29th July for every 10 year. One of the most remarkable changes from the present climate to the global warming climate is the extreme increase of the rainfall amount especially around the southern Kyushu in the Baiu season (Yoshizaki, et al, 2005). It results from not only the extension of the Baiu season but also the intensification of daily rainfall amount of the global warming climate. Three-dimensional structure of rainfall-systems is examined in the global warming climate. Upward sifts of peak levels with 0.5-1.0 km from the present climate are found in the mixing ratios of cloud, snow and rain water. Both time-averaged vertical velocity and peak-values of the mixing ratios of cloud and rain water around the southern Kyushu and its upwind area of the global warming are larger. Interestingly, the layer of large cloud water mixing ratio is much thicker in the global warming climate around the southern Kyushu. These features indicate the high possibility that the structure of rainfall-systems are modified in the global warming climate.
