摘要 基于国际上先进的第三代近岸海浪数值模式SWAN,对影响南海湛江港典型路径台风(西北型、北上型、打转型)过程所产生的台风浪进行了较高分辨率的模拟研究,计算结果较为客观、准确地描绘了这些台风浪过程的主要特征;同时利用该海域硇洲岛测站台风浪观测值与模拟结果进行了比较,二者吻合较好。在此基础上,进一步分析了外海涌浪的传入对湛江港内波浪场的影响以及不同风速、风向控制下港口内波浪场的分布特征。结果表明:外海涌浪对该港口内波浪场影响较小,而不同方向台风风场的直接作用对该港口内波浪场影响极大,研究结果可为该海域的防台减灾和台风浪的预报提供较好的参考。 In this paper, we simulate the typhoon waves around the Zhanjiang port using the SWAN wave model. The result presents the process of typhoon waves objectively and correctly. It is also accord with the real wave data very well. We also analyze the effect of outer sea swell on the port and the wave characteristics under the control of different wind velocity and direction. All the result shows that the effect of outer sea swell is very little on the port, but the effect of the wind direction and velocity is very big. These results will provide a very good reference for the area's defence and forecast of typhoon.
