Abstract
In this study, future change of precipitation characteristic was examined using the multi-GCMs of CMIP3 (including 24 models) and MRI-AGCM (3.1S and 3.2S). The standard deviation of monthly precipitation and daily precipitation intensity in the top 2% were
evaluated. The former is related to drought, the latter is related to flood. The result shows that both index would increase in the future, depending on the GCM.
