湛江近海全日分潮的数值模拟

Numerical Simulation of Diurnal Tide Components in the Sea Near Zhanjiang

通过采用二维水动力学数值模式和高分辨率的自适应曲线网格 ,模拟湛江附近海域主要全日分潮K1和 O1分潮 ,比较了潮汐调和常数的模拟值和实测值 ,并给出 K1和 O1分潮的同潮图及涨憩、落憩、涨急、落急等各时刻流场 。

The numerical tidal model and a high-resolution self-adaptive curvilinear grid is introduced with the aim of simulating the movement of the main diurnal constituent, i.e. K_1andO_1, in the sea near Zhanjiang. The error of tidal harmonic constant in simulation is slight as compared with the observed value. With the cotidal chart of K_1andO_1 and the current field graphics at four typical moments plotted, the movement law of tide and tidal current of diurnal constituent is revealed.
