Studies on the effects of climate change on waves and storm surges have been widely conducted. In comparison with storm surges, there is a lack of information on the future prediction of waves because of the high computational cost. One of the methods to reduce the computational cost is the statistical wave model. Wind speed and pressure are used as predictive variables, but they are not accurate because local equilibrium is not established in the sea area where seasonal changes of swell are dominant. In this study, by introducing the principal component information of the atmospheric field, a highly accurate statistical wave model is developed by adding the atmospheric field in a wide area as an explanatory variable.
