摘要

摘要: 通过象山港水域的潮波运动数值模拟,分析了象山港M₄分潮的生成和增长机制.结果说明,潮波传播中的非线性底摩擦效应是M₄分潮生成和增长的主要控制因子,M₄分潮在湾内的共振现象也起着重要的放大作用二平流效应在绝大部分区域中抑制了M₄分潮的发展,只有在佛渡水道中一些岛屿周围极小区域内对M₄分潮有增强作用.潮滩在湾内对M₄分潮的影响极其微弱.

Abstract: The mechanisms of M₄ tide component are analyzed by means of a tide modelling in the Xiangshan Bay.The result shows that the generating and developing processes of M₄ tide component are controlled mainly by the effects of the nonlinear bottom friction during the tide wave propagation.The M₄ tide co-oscillation is important to amplify the M₄ tide in the Xiangshan Bay.The effect of advection amplifies the M₄ tide only in the small individual area near some islands located in the Fudu Channel.The tidal flat has a little effect on the M₄ tide.
