利用WAVEWATCH海浪模式分别对1104号“海马”、1105号“米雷”两个连续登陆中国沿海的台风进行数值模拟,将数值模拟的有效波高、平均周期与浮标站实测资料进行了对比。结果表明,台风影响下的海面风场和台风浪波高的空间分布具有近似的对称结构;波高与风速在台风中心左右两侧分布不同。从时间来看,台风发展过程中风速的变化对波高产生了明显的影响,说明波高对风速有很强的依赖性。数值模拟结果表明WAVEWATCH可以反映台风浪的基本特征。
Using WAVEWATCH wave model to conduct numerical simulations of two consecutive typhoon landed on the coast of China, including No. 1104 “Hippocampus ” and No. 1105 “Mile ”, respectively, the effective wave height and average period of numerical simulation were compared with that of buoy observation data Compared. The results show that the spatial distribution of sea surface winds and typhoon wave waves under the influence of typhoon has an approximate symmetrical structure. The wave height and wind speed are distributed differently on the left and right sides of the typhoon center. From the point of view, the change of wind speed during typhoon development has a significant impact on wave height, indicating that wave height has a strong dependence on wind speed. Numerical simulation results show that WAVEWATCH can reflect the basic characteristics of typhoon waves.
