Recently, due to global warming, there are growing concerns about possible tremendous storm surge disasters which might be caused by furious typhoons more than ever. Actually, however, even in the present climate conditions, there were some typhoons which might be able to cause severe disasters if it were in the worst case scenario, for example typhoon 1216. Fortunately, the typhoon 1216 didn't cause serious damage in the Ariake Sea since its track was away from Kyushu district. In this paper, we conducted several storm surge simulations with the parameters of the typhoon 1216 by assuming several different typhoon tracks including the worst track. The results show that the maximum storm tide would exceed the existing disaster prevention plan even in the present climate conditions if it had passed in the worst track.
