摘　　要：利用 97版 POM模式对环台湾岛海域 M2 分潮作了分辨率较高的三维数值模拟。在较准确地模拟了潮汐分布的基础上 ,研究了 M2 分潮流椭圆分布、最大流同时线分布以及潮流场结构。结果表明 ,环台湾岛海域的 M2 潮波主要为大洋传来的胁振潮 ,台湾海峡为强潮区 ;M2 分潮最大流同时线在海峡中部形成密集区 ;构成海峡潮波系统的两支潮波中 ,北支潮波的强度远大于南支潮波 ,其影响范围可以到达台湾浅滩南缘 ,但两支潮波影响范围并没有达到“台湾西岸中段”Three dimensional numerical study of M 2 tide characteristic is made with fairly high resolution using version 97 POM (Princeton Ocean Model).First of all,tidal distribution is simulatd with high precision and the cotidal chart is provided.Based on this work,the distribution of M 2 tidal current ellipse,the cotidal current line and the horizontal structure of tide current field are studied.The results show that M 2 tidal waves in the sea area around Taiwan Strait Island are formed by tide invasion from the Pacific Ocean.and Taiwan Strait is a strong tide area;There is a M 2 maximum tidal current concentrative zone of cotidal current line in the middle of the Taiwan Strait.;The tidal waves of the Taiwan Strait is constituted by two waves coming from the north and the south,the northern branch is much stronger than the southern branch.
