把从T0PEX/Poseidon卫星高度计资料中提取的沿轨道分潮的调和常数同化到二维非线性潮汐数值模式中,对台湾岛毗邻海域进行数值同化模拟.所用的同化方法为伴随同化方法,该方法的主要作用是校正开边界条件和底摩擦系数.结果表明:利用该方法对研究海域四个分潮调和常数的计算精度较高、速度快,克服了常规人工给定开边界和底摩擦系数计算潮汐所遇到的困难和不足.
The assimilation constants of orbital tidal components extracted from the T0PEX / Poseidon satellite altimeter data are assimilated to the two-dimensional nonlinear tidal numerical model for numerical assimilation simulation of the adjacent waters of Taiwan Island.The assimilation method used is the assimilation method, The main function of this method is to correct the open boundary conditions and the bottom friction coefficient.The results show that this method can be used to calculate the harmonic constant of the four moisture points in the study area with high precision and fast speed, Tides encountered difficulties and deficiencies.
