摘　　要：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 oceanic model, POM 97, we do a 3-D numerical study on the synthetic property of diurnal constituent, tide and tidal current of the sea regions around Taiwan Island, where the diurnal constituent comes from the Pacific, and the tidal wave coming from the sea regions of the north of Taiwan Island passes through the channel. The diurnal constituent coming from the Lvsong Channel has something important to the maintenance of the tidal movement of the South China Sea. There are five round stream dots on the distributive surface layer of the isochrones of maximum stream of the diurnal constituent, and four of them are discovered for the first time. The Taiwan Channel, its northern sea regions and its eastern ocean areas are fields of abnormal semi-diurnal constituent, while the east southern of Taiwan are mixed tidal fields where diurnal constituent are the most. The sea regions on the north of Taiwan are the cyclonic eddy areas of the residual current, and the shallow sands around Taiwan are the anticyclonic ones. The turning current beginning at the Peng lake watercourse indicates the coming of flood-tide stream or ebb-tide one on Taiwan Channel and its neighboring sea regions.
