采用POM模式研究了南海对于台风伊布都的响应过程.结果表明:台风过后,海洋表面温度下降2—6℃,且在台风路径两侧不对称,具有明显的右偏性.受台风强混合作用的影响,混合层加深10—60m,上混合层热量损失约824.78W/m2,其中垂向混合是造成热量损失的主导动力因素.由于受上混合层热通量输送的影响,混合层以下附近水层处于增温状态,海水温度做近惯性波动.同时,台风还能引起强烈的近惯性流,最大流速出现在上混合层,可达1.4m/s.

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. 相似文献
