Abstract

The influence of global warming on hazard risk is estimated from the results of the regional climate model by Japan Meteorological Agency and Meteorological Research Institute. The horizontal resolution of the model is about 20km and the model outputs are expected to be useful for the risk assessment of the future. Before beginning the risk assessment, the model output values during 1981-2000 were verified by comparing with observed precipitation data. The verification shows that the precision of the models are generally well in representation of the extreme precipitation distribution of the annual maximum daily precipitation. According to the analysis from the model outputs, the extreme daily precipitation in 100-yr time period will increase in some parts of western Hokkaido, northern Tohoku region, Hokuriku region and Nansei islands during 2081-2100.
