| 摘 要： | 通过半封闭矩形理想海湾的潮波运动数值模拟,分析了潮滩及平流效应对M4分潮的生成和增长的影响.结果说明潮滩的作用不但依赖本身的规模和湾内潮波非线性的强弱,而且与潮滩在湾内所处位置关系很大.在存在M4分潮共振的海湾中,平流效应可以抑制共振对M4分潮的放大作用.

| Abstract: | The contribution of the tidal flat and tidal currents advection to the generation and growth of M4 tidal component isanalyzed by using a numerical modelling in a ideal semi-enclosed rectanglular bay. The result shows that the contribution of tidal flatdepends not only on the location and dimension of the tidal flat, but also on the non-linearity of the tide in the bay. The amplitudeof the M4 tidal component is inhibited by the advection in the bay where there is the M4 tide co-oscillation. |
