用97版POM海洋模式 ,对环台湾岛海域的全日分潮和整个潮汐、潮流综合特征进行三维数值研究。研究海域全日分潮是由太平洋传入的 ,且来自台湾岛北部海区传入的潮波穿越海峡。由吕宋海峡传入的全日分潮对维持南海的潮运动起着重要作用。全日分潮最大流同时线分布表层有5个圆流点 ,其中4个本文首次得到。台湾海峡及其以北海区和台湾东部洋区为不规则半日潮区 ,台湾东南为全日分潮为主的混合潮区。台湾岛北部为气旋式余流涡旋区 ,环绕台湾浅滩为反气旋余流涡旋区 ,澎湖水道开始的转向流预示着海峡及其邻近海区的涨潮流或落潮流的来临。
Using the 97th POM ocean model, the three-dimensional numerical study of the full-day component tidal and tidal and tidal current characteristics around the island of Taiwan Island was conducted. Full-day tidal waves in the study area are introduced from the Pacific Ocean and incoming tidal waves from the northern part of Taiwan Island cross the Strait. The full-scale tidal currents introduced by the Luzon Strait play an important role in maintaining the tide movement in the South China Sea. At the same time, the maximum flow of full-tidal tidal current has 5 circular flow points on the surface, of which 4 are obtained for the first time. The Taiwan Strait and its north sea area and Taiwan’s eastern ocean area are irregular half-tidal tidal areas, and southeastern Taiwan is an all-day tidal tidal mixed tidal zone. The northern part of Taiwan Island is a cyclonic overcovortex, which surrounds the Taiwan shoal as the counter-cyclonic overcurrent swirling zone. The diverting flow initiated by the Penghu waterway indicates that the tidal current or the falling tide of the strait and its adjacent sea areas are coming.
