琼州海峡附近海域2014年强台风下潮位的数值模拟与特征分析

建立了天文潮与风暴潮耦合模型,对2014年经过琼州海峡的1409号与1415号台风进行风暴潮数值模拟,比较表明,模拟结果与实测结果相吻合,数学模型具有较好的天文潮和风暴潮耦合计算适应性。结果表明:台风经过琼州海峡时,雷州半岛东部会出现最大增水,琼州海峡东部增水较为显著。1415号台风经过琼州海峡时,海口秀英站最高水位超警戒水位1.57 m,为有记录以来历史最高水位。

Numerical Simulation and Characteristics Analysis of the Water Level near Qiongzhou Strait Caused by 2014 Strong Typhoon

A coupled model of astronomical tide and storm surge was established. The numerical simulation of the tide and storm surge in the Waters near Qiongzhou Strait caused by Typhoon No. 1415 and Typhoon No. 1409 in 2014 was carried out. The simulation results are in good agreement with the measured results. The model has a good adaptability to the coupling computationa of astronomical tide and storm surge. The results show:when the typhoon passes through the Qiongzhou Strait, the largest surge was in the eastern part of the Leizhou Peninsula, and the surge in the eastern part of the Strait was significant. When Typhoon No. 1415 through the Qiongzhou Strait, the level in Haikou exceed the alert level 1.57 m, which was the historical highest level since records.
