本文依据二维长波方程,用有限差分方法计算了朝鲜海峡的半日潮和全日潮,得到与实际观测符合良好的结果。文章给出了潮汐、潮流和能通量的分布。计算显示,在朝鲜半岛东南方的全日潮无潮点位置比历史同潮图上的位置更靠近朝鲜海岸。计算还发现在五岛列岛西北方向存在一个M_2潮流的圆流点。能通量计算表明,潮能系从济州岛和九洲之间的通道进入本海区。除本海区消耗外,部分能量通过对马岛和九州之间的通道进入日本海,部分则通过济州岛和朝鲜半岛之间的通道流向黄海。
Based on the two-dimensional long-wave equation, this paper calculates the half-day tide and the full-day tide of the Korea Strait by using the finite difference method, which is in good agreement with the actual observations. The paper gives the distribution of tidal, tidal current and flux. Calculations show that the tidal full point at southeast of the Korean Peninsula is located closer to the coast of North Korea than the position on the same historical map. It is also found that there is a circular flow point of M 2 flow in the northwest of Wudao archipelago. The flux calculation shows that the tidal energy enters the sea area from the channel between Jeju Island and Jiuzhou. Except for the consumption of the sea area, some of the energy enters the Sea of Japan through the passage between the Falklands and Kyushu and partly to the Yellow Sea through the channel between Jeju Island and the Korean Peninsula.
