| 摘 要： | 基于采用不规则三角网格和有限体积方法的FVCOM模式,建立钦州湾三维潮流数值模型来重现钦州湾的潮位和潮流变化状况.根据模拟结果计算得到了较以往更为精细的钦州湾K1、O1、M2、S2分潮的同潮图,潮汐最大振幅分别为112、96、50和15cm;最大可能流速的分布基本与等深线一致,龙门港附近最大可能潮流流速可达200cm·s-1;钦州湾的外湾口海域开阔,一般为旋转流,近岸海区及水道、河口等多为往复流,K1和M2分潮流椭圆长轴的分布与地形密切相关,旋转方向均为顺时针,流速极值出现在龙门港区.由潮余流场的分布特点可以看出,钦州湾西槽和中槽的西侧区域是其主要的出水通道,东槽和中槽的东侧区域则是主要的进水通道.

| Abstract: | Based on an unstructured grid,finite-volume coastal ocean model(FVCOM),the complete three-dimensional fine-solution equation group of shallow-sea tide is adopted to calculate the tide in Qinzhou Bay.The equation group consists of tide-control equations and obturating turbulence equations.Using harmonic analysis of the calculated tidal level and current,the distributions of co-tidal lines for K1,O1,M2 and S2 are obtained,whose maximum amplitudes can reach 112 cm,96 cm,50 cm and 15 cm,respectively.The distrib... |
