Abstract
We introduce climate change projections of extreme precipitation. First, numerical experiments of climate changes in the Baiu frontal precipitation using a non-hydrostatic regional climate model were performed. The model well reproduced intense precipitation with shorter accumulation periods while GCMs could not. The characteristic feature of future climate shows that the enhancements of precipitation and extreme values around the Kyushu District in association with the enhancement of diabatic heating effect.
Second, reproducing of more extreme precipitation from GCMs is considered using statistical approach. PDF of precipitation intensity with variation of atmospheric condition is newly introduced. Three parameters of the PDF are statistically estimated by the results of GCM.
