| 摘 要： | 基于POM模式，采用第一类水位、流速和Flather（1976）3种开边界条件，模拟了东海的M2分潮．结果表明，在这3种开边界条件下，均能成功地模拟M2分潮的传播特征，以及在该海区内的三个半无潮点．计算结果与实测的较吻合，并且在Flather开边界条件下，模拟的振幅和迟角与实测资料的偏差分别为5．62cm和7．90°，效果最好．这也说明Flather开边界条件是潮汐模拟当中较可取的一种开边界条件．

| Abstract: | Based the POM(princeton oceanic model) and using clamped elevation,clamped normal velocity,and Flather(1976) the M_2 tidal constituent in the East China Sea was simulated.Three open boundary conditions have given similar results,which are comparable to the observed data from gauging stations.It simulated successfully the M_2 tidal wave propagation features and 3 semi-amphidromic point in the East China Sea.It also showed that Flather open boundary condition was better than that of others and the RAM of model predicted amplitude and phase of the M_2 tidal constituent are 5.62cm and 7.90°.The results proved that Flather open boundary condition is an acceptable ones for the tidal simulation. |
