Climate change due to global warming is expected to have major impacts on phenomena such as tropical cyclones (TCs), Baiu, precipitation, and seasonal storms. Many natural disasters in East Asia are driven by TC (typhoon) activity in particular and their associated hazards are sensitive to local-scale characteristics. As such, it is critically important to numerically simulate TC activity (and other phenomenon) on local scales in order to properly assess climate change impacts on natural hazards in the region. In addition, projecting future changes of many TC-related hazards and/or their potential economic impacts can be challenging due to their low occurrence frequencies in any one particular area. With these views in mind, a collaborative research program was formed in Japan to project long-term changes in natural hazards in Japan and East Asia based on local-scale and large-ensemble numerical experiments. This paper reviews recent climate change impact assessments (written in both English and Japanese) from the program and summarizes the projected future changes in precipitation, river flooding, and coastal hazards, and their associated economic impacts.

预计由于全球变暖导致的气候变化将对诸如热带气旋（TCs），Baiu，降水和季节性风暴等现象产生重大影响。东亚的许多自然灾害尤其是由台风（TC）活动驱动的，其相关危害对地方尺度特征敏感。因此，至关重要的是在地方尺度上对TC活动（和其他现象）进行数值模拟，以正确评估气候变化对该地区自然灾害的影响。此外，由于在任何一个特定地区的发生频率都很低，因此预测许多与TC相关的危害的未来变化和/或它们潜在的经济影响可能是具有挑战性的。考虑到这些观点，日本成立了一个合作研究计划，根据当地规模和大型整体数值实验预测日本和东亚的自然灾害的长期变化。本文回顾了该计划的近期气候变化影响评估（用英语和日语编写），并总结了预计的未来降水，河流洪水和沿海灾害的变化及其相关的经济影响。
