Abstract
This study investigated the wind speed with a reproduction period of 50 years, that of 500 years and typhoon characteristics at landfall for each area in Japan for each experiment using current climate experiment (HPB), +2℃ experiment (HFB_2K), +4℃ experiment (HFB_4K) data of global model of database for Policy Decision making for Future climate change (d4PDF). The results revealed that the wind speed with a reproduction period of 50 years and that of 500 years of HFB_4K on land in Japan were 1.05 to 1.10 and 1.05 to 1.15 times higher than those of HPB, therefore buildings may be subjected to stronger wind loads than at present if global warming continues. In addition, this study revealed that typhoons at landfall in Japan in HFB_2K and HFB_4K were more developed than HPBs, and in some landfall areas they traveled slower. This showed that duration of strong winds may be longer and winds on the left side of near the center of the typhoon may be stronger. On the other hand, it is thus possible that winds may weak on the right side of near the center of the typhoon.
