摘要
作者以 72 0 3号台风过程中引起的黄海沿岸水文测站的风暴潮过程为例 ,选取不同计算域 ,模拟计算的同一测站的风暴潮增水值有很大差异。只有选取整个黄渤海海域 ,才能得到较精确的风暴潮增水结果。从而揭示在封闭或半封闭海域中由风暴过程激发的区域自由振荡 ,是风暴潮增水中不容忽视的量。说明该海域中的风暴潮过程是海域整体效应的响应 。
The Author numerically simulated one of typhoon surge (caused by No. 7203, typhoon Rita), which occurred in the Bohai Sea and the Yellow Sea by using three different calculation fields. Different results were obtained, which means that the calculation field will significantly influence the simulated results. This event shows that the storm surge is a process of forced oscillation, it will generate free oscillations in a closed or semi closed sea, and the sea will modulate this forced oscillation. That is to say, the geometric shape of the sea will seriously affect the process of the storm surge in a closed or semi closed sea. Therefore, The satisfactory results can be obtained only when the calculation field covers the whole region.
