The aims of this study are to examine the reproducibility of new Meteorological-Surge-Tide coupled model and to estimate the effect of global warming to storm surge. In order to examine the model, the case of typhoon Roke (2011) is taken to be an example since the sea level elevation in this case is the highest record in Tokyo Bay during recent 10 years. For the case of typhoon Roke, the tendency of time history of water level is well reproduced though the maximum value is underestimated. The future case of typhoon Roke is also calculated. The sea level at Shibaura is increased for around 20cm and it is also increased around 40cm at Funabashi. These results imply that the coupled model has good performance but there are still some differences of sea level at Tokyo Bay due to the effect of complex geography.
