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.
