| 摘 要： | 采用球面潮波运动基本方程,利用开边界强迫水位条件和考虑天体引潮力,对渤、黄、东海现有的潮波进行数值模拟。模拟包括19个理论系数最大的分潮波,其中半日潮波10个,全日潮波9个,对如此多数目的分潮波进行模拟是第一次尝试。模拟结果与实测资料作了比较。根据模拟获得的调和常数绘制了同潮图,并对潮波运动进行了讨论和分析。

| Abstract: | Current tidal waves in the areas were modeled by using the spherical tidal wave equations with the tide-generating force taken into account,and with an open boundary condition taken as forced tidal elevation.The modeling covered 19 tidal constituent waves with the largest theoretical coefficients,including,10 semidiurnal and 9 diurnal constituents.This was the first attempt at modeling so many tidal constituent waves.The modeled results were compared with observed data.Co-tidal charts were drawn based on the modeled harmonics,and the movements of the tidal waves were discussed and analyzed. |
