Future projections of global and the North West Pacific wave climate under global warming scenario were conducted and the uncertainties related with different Sea Surface Temperatures (SSTs) were investigated, based on SST-ensemble experiments performed by an atmospheric general circulation model and a wave model. Future changes in average wave height show same or opposite signals among the series of experiments depending on the ocean and season. Especially in the North West Pacific, the uncertainties of future wave climate in summer are larger than other oceans due to uncertainty in projection of typhoon characteristics.
