建立二维潮波模式,模拟了台湾海峡及其邻近海域(18～30°N,110～130°E)八个主要分潮(M2、S2、K1、O1、P1、Q1、K2、N2),并利用中国大陆及环台湾岛20多个潮位站的实测资料进行验证,计算结果与实测值吻合良好。此外,给出了八个主要分潮的同潮图,并逐个讨论了潮汐特征。结果显示:(1)台湾海峡中的潮波运动是北部蜕化了的旋转潮波系统和南部的前进潮波系统共同作用的结果。(2)半日分潮南、北两支潮波在台湾海峡中部汇合,而全日分潮则在台湾海峡南部海域汇合后继续朝西南方向传播。(3)半日分潮振幅最高值发生在福建省湄洲湾—兴化湾一带,全日分潮最高值则出现在雷州半岛以东一带近岸海域。(4)N2、K2和O1、P1、Q1分潮的振幅、迟角分布分别同M2与K1分潮的整体分布趋势相似。
A two-dimensional tidal wave model was established to simulate the eight main tidal currents (M2, S2, K1, O1, P1, Q1, K2 and N2) in the Taiwan Strait and its adjacent sea areas (18-30 ° N, 110-130 ° E) , And verified by using the measured data from more than 20 tide stations in mainland China and Taiwan. The calculated results are in good agreement with the measured values. In addition, the tide diagrams of eight main tides are given, and the tidal characteristics are discussed one by one. The results show that: (1) The tidal wave motion in the Taiwan Strait is the result of the combined action of the degenerated rotating tidal wave system in the north and the advancing tidal wave system in the south. (2) Semi-diurnal tide The south and north tidal waves converge in the middle of the Taiwan Strait, while the full-day tidal currents continue to spread southwestward after merging in the southern waters of the Taiwan Strait. (3) The highest amplitude of semi-diurnal tide occurred in Meizhou Bay - Xinghua Bay, Fujian Province. The highest tidal fullness occurred in the coastal area to the east of Leizhou Peninsula. (4) The amplitudes and the late angle distributions of moisture in N2, K2, O1, P1 and Q1 are similar to those of M2 and K1, respectively.
