| 摘 要： | 采用二维非线性潮波微分方程对渤海M_2、S_2、K_1、O_1四个分潮进行数值模拟,得出四个分潮的潮波图,椭圆长短轴图,同潮流时图以及潮汐、潮流性质图和S_2与M_2、K_1与O_1的迟角差图。依此可以系统地了解渤海潮波系统的分布变化规律。依据30～40年代测得的渤海海图以及假设数十年后渤海的岸形对渤海进行数值模拟,从而了解过去和现在渤海潮波的变化情况,以及对未来潮波的变化作出判断。计算表明,从30年代到70年代以来,渤海南部的半日分潮波发生了很大的变化,而日分潮的潮波变化较小。

| Abstract: | In this paper,the M2,S2,K1 and O1 tides and their tidal currents of the 1970s in the Bohai Sea are computed using the alternating direction implicit method based on the two-dimensional nonlinear tidal wave equations.In order to study the variations of the tidal waves in the Bohai Sea,we also compute the M2 and K1 tides and tidal currents of the 1930s and several decades later in the Bohai Sea.The computation shows that the southern system of the semidiurnal tidal waves in the Bohai Sea has greatly changed because of the change of boundary and water depth in the Bohai Sea from the 1930s to the 1970s,but the diurnal tidal waves have only changeci slightly. |
