| 摘 要： | 分析四象限非对称风场模型与叠加风场模型的优缺点,将模型结果与实测风速进行对比验证;利用上述两种风场模型分别驱动第三代海浪模式SWAN,对发生在南海海域的三场台风浪进行了数值模拟计算。结果显示:四象限非对称模型关于风速的计算值与实测值吻合度更高,尤其是当台风中心距离测站较近时;四象限非对称模型驱动SWAN模拟的台风浪精度优于叠加风场模型,适用于南海台风浪的数值模拟。

| Abstract: | We analyze the advantages and disadvantages of the four-quadrant asymmetric wind model and the superimposed wind model by comparing the numerical results with observations. The two wind models are used to drive the third-generation wave model SWAN to simulate the typhoon waves of three typhoon events in the South China Sea. The results show that the wind speed of the four-quadrant asymmetric wind model coincides better with observations, especially when the typhoon center is close to the observation stations.. The accuracy of typhoon waves driven by the four-quadrant asymmetric model is better than that of the superimposed wind model. As a result, the four-quadrant asymmetric wind field model is more suitable for the numerical simulation of typhoon waves in the South China Sea. |
