摘要
将摩擦力项取为线性形式,联合考虑了科氏力、摩擦力以及非摩擦非线性 效应,给出了等深海峡中源潮波及浅水潮波解析形式的解;探讨了各分潮波振幅的 分布变化情况,并将本文的解析模式应用于台湾海峡及南海东北部海域;计算了 M2,S2,M4和MS44个分潮的理论解。与实际观测比较表明,在台湾海峡内,半日潮 和四分日潮解析解与实测符合较好;在南海东北部,半日潮波解析解与实测差异较 大。作者认为这是由于来自吕宋海峡传入的潮波的影响。四分日潮波解析解与实 测仍较一致,表明南海东北部四分日潮仍主要受来自台湾海峡潮波控制。
An analytic solution of primary tidal waves and shallow-water waves in a strait with uniform width and depth is obtained. The Coriolis force, linear friction and non-frictional nolinear effects are considered in the study. Discussions on the variation of the amplitudes of primary and shallow-water tidal waves are also presented. As an application, the analytic solution has been used in the Taiwan Strait and the northeast part of the South China Sea. M2, S2,M4 and MS4 tides have been Calculated, showing (l) in the Taiwan Strait, both the semi-diurnal and the quarter-diurnal tidal waves are consistent with observed results. (2) in the northeast pert of the South China so, agreement between calculated and observed quarter-diurnal tidal waves is satisfactory, indicating that the quarter-diurnal waves in the northeast pert of the South China Sea are mainly dominated by tidal waves from the Taiwan Strait. But the calculated semi-diurnal tidal waves do not agree with the observed ones. This is mainly attributed to the primary tidal waves from the Lu Song Strait.
