EVALUATION OF STORM SURGES AROUND THE KOREAN PENINSULA IN PRESENT AND FUTURE CLIMATES

Abstract

This study evaluates the storm surge around the Korean Peninsula due to the climate change based on results of a coupled model of surge, wave and tide (SuWAT), which is directly forced by the output sets of the present (1979-2008) and future (2075-2099) climates projected by MRI-AGCM model of the Japan Meteorological Agency. It is found that the intensity and the number of the future typhoons increase around the Korean Peninsula and their tracks move toward the east in comparison with the present tracks. As a consequence, the extreme analysis indicates that the storm surges in the future climate are enforced along the south coasts of the Korean Peninsula, especially. The study represents that the effect of the climate change on the storm surge should be taken into account with the coastal-scale variation.
