Effect of oceanic current on typhoon-wave modeling in the East China Sea

摘要

We use the WAVEWATCH-Ⅲ model to quantify the effect of oceanic current on typhoon-wave modeling in the East-China-Sea (ECS).Typhoons Jelawat and Saomai in the autumn of 2000 are hindcasted.The oceanic currents in the ECS are mainly constituted of Kuroshio and typhoon-generated currents.The results show distinguishable differences in wave height and wave period under the typhoon conditions.The oceanic current causes the maximum differences,of up to a 0.5 m significant wave height and a 1 s mean wave period.Comparisons between typhoons Jelawat and Saomai show the dependence of the current effect on the typhoon characteristics.
