本文对北部湾三维潮波进行了数值研究,并将所得结果与现有观测资料作了比较。通过比较发现两者相当一致。文中还绘制了M_2和K_1分潮的同潮图,并对其作了讨论。可以断定,北部湾的日潮优势是由日潮共振所引起的。M_2和K_1分潮流的水平分布表明,强流区位于它们各自的蜕化无潮点附近。还讨论了分潮流的铅直结构,可以看出这种结构十分接近实际分潮流场的特征。
In this paper, a numerical study of the three-dimensional tide waves in the Beibu Bay has been carried out. The results obtained are compared with the existing observations. By comparison found that the two are quite consistent. The paper also draws the same tidal diagram of M_2 and K_1 tide, and discusses it. It can be concluded that the advantage of the daily tide in the northern Gulf is caused by the tide of the tide. The horizontal distribution of tidal currents in M_2 and K_1 shows that the strong current areas are located near their respective non-tidal degeneration points. The vertical structure of tidal current is also discussed and it can be seen that this structure is very close to the characteristics of the actual tidal current field.
