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。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
