Though adopting the - coordinate transformation in the control equations and mode - splitting technique , the external mode ( surface gravity waves ) is solved by the improved double - sweep - implicit finite difference method ; the internal mode ( internal gravity waves ) untilizes the eulerian - lagrangian method , which improves the implicit - difference scheme for the vertical direction . the newly developed 3d numerical tidal model with implicit scheme has been successfully applied in the radial sandbanks area 基于過程分裂法及垂向坐標伸縮變換，外模式采用改進型雙步全隱有限差分dsi法，內模式采用歐拉?拉格朗日公式，改進了三維垂向隱式格式，成功地建立了南黃海輻射狀沙脊群海域三維全隱格式潮流數學模型。 |
