【摘要】 本文用ADI方法模拟了金塘水道及其邻近海域的M₂潮流和余流分布,计算结果与实测结果吻合良好。潮位、潮流的平均相对误差分别为5.2%和6.7%。探讨了金塘水道东口潮余涡的形成机制。实验证明,该余涡主要是横向边界效应作用的结果,所得结论与有关的理论分析结果是一致的。更多还原

【Abstract】 The M2 tide and tidal residual currents of the Jintang Channel and the adjacent water area were computed by using ADI method.The computation results were quite identical with those from data by a relative average error of 5.2% for tidal level and 6.7% for tidal currents.Through a series of experiments,it can be confirmed that the main production mechanism of the tidal residual vorticity occurring at the east end of the channel is subject to the horizontal boundary effect.This conclusion is consistent with some theoretical analyses.更多还原
