| 摘 要： | 本文利用POM模式模拟了季风在台湾海峡引起的风海流以及三维流场结构。在冬季和夏季两种条件下，得出了季风引起的水位变化和三维流场结构。结果显示在冬季季风的作用下，海峡的东部北部发生减水而西南部产生增水；在夏季海峡北部产生增水而东南部和西南部产生减水，在科氏力的作用下，风海流表层流向偏于风向右侧。风海流在20m处形成的流场和底层流场本文也给出了模拟结果。流速的艾克曼螺线显示；该海域的流速并不随水深加大而一致减小，而是先减小至一定深度再稍微增大，然后继结衰减而零。

| Abstract: | Based on the POM model, the numerical simulation of wind current is studiedunder monsoon condition in Taiwan Strait. It is disclosed how the surface elevation and 3D velocity structure distribute in Taiwan Strait. In winter, the surface elevation of the southwest turns higher while the east and north lower, and in summer the north turns higher while the southwest and southeast lower. The outcome shows that the surface velocity direction is deviated from the wind. The velocity field at 20m depth and bottom is also discussed in this paper. This paper also shows how the velocity varies with depth, and draw a conclusion that the maximum velocity is not in the surface but in a certain depth. |
