| 摘 要： | 以河口海岸海洋模型ECOM和第三代海浪模型SWAN为基础,以全球天文潮预报模式TPXO6.2和台风参数模型风场及气压场作为驱动,采用海洋-陆架区-海岸三重嵌套网格,建立了适用于深圳香港水域天文潮-风暴潮-台风浪耦合模型。以0814号台风"黑格比"为算例,进行了耦合模拟计算,计算结果显示,天文潮、风暴潮位和浪高与实测值符合良好,天文潮的均方根误差小于0.15 m,有效波高误差0.9 m,风暴高潮位平均误差0.23 m;并分析了风暴潮位和波浪的相互影响,以及深港水域波浪场的分布,4 m水深考虑风暴潮位影响有效波高提高0.40 m,沿岸波浪增水在0.20 m以内。

| Abstract: | This paper describes a coupling model that simulates storm tide and waves induced by typhoon in Shenzhen and Hong Kong waters.The coupling model is based on the nonlinear long-wave model ECOM and the third wave model SWAN driven by the parametric typhoon model and the global tide model TPXO6.2 for three levels of nested geographic domains,ocean,continental and coastal.No.0814 typhoon Hagupit was chosen for case study to test the coupling model,and the computed results show the good agreement with the observ... |
