One of fearful impacts to coastal zone in future is change in intensity of tropical cyclone on global warming. The purpose of this paper is projection of future storm surges due to the tropical cyclones and vulnerability assessments by the storm surges in coastal zones. Outputs of a global climate model were used for trend of change in the sea surfaced pressure of tropical cyclones. A numerical simulation was employed to project storm surges. Projected results showed future storm surges become higher along coasts of Gulf of Mexico and east coast of America, and East-Asian coasts facing to Pacific Ocean. The results of vulnerability assessment showed that change in intensity of tropical cyclone is big impact as same as impact of rise in sea level and population growth, particularly in Asia coastal zones.
