Response of extreme significant wave height to climate change in the South China Sea and northern Indian Ocean

Abstract The frequency of extreme wave events is increasing with climate change. temporal and spatial variations height affect both human livelihood the usage ocean resources. South China Sea northern Indian Ocean support coastal communities high population density, varied terrain structures wind systems. This study focuses on significant in Ocean. Using nonstationary generalized value analysis, trends for a 100-year return period were obtained both. most rapid increase was found to be 0.015 m yr-1 Arabian Sea; however, fell mouth Bay Bengal. After analyzing possible causes influence factors, we that dominated by local wind-waves similarly, affected swell. NINO3.4 index shows good correlation because typhoons are related this area. southern Bengal have correlations Asian summer monsoon index.
