摘要
浅海是潮运动占优的海域，潮汐、潮流对物质输运和水交换有重要影响．采用非结构有限体积近岸海洋模型（FVCOM）模拟渤海湾的三维潮汐潮流分布和变化规律，非结构网格能真实地拟合岸线，刻画出渤海湾的复杂岸线，能够较好地计算出渤海湾的潮汐潮流的时空分布特点，与实测值吻合较好．模拟的M，分潮振幅的平均方差为7．33cm，迟角的平均方差为11．53°．在渤海湾，M2分潮的最大振幅为120cm，湾内的迟角差为70°；渤海湾湾中潮余流较弱，流速在0—0．6cm／s．渤海湾是潮流较强的区域，海区的最大可能潮流流速超过100cm／s．
The shallow sea is dominated by the tidal movement, so the tides and tidal currents are important for the material transport and water exchange. The unstructured grid 3 D FVCOM （finite volume coastal ocean model）has been applied to Bohai Bay to simulate the distribution and variation of the tides. By accurately resolving the irregular coastlines and bathym- etry in the coastal regions, the simulated tidal parameters agreed well with the available observation data, and can capture the tidal structure in Bohai Bay. The maximum amplitude of M2 is about 120 cm, and the spacing of the phase is about 70°. The residual current is small in the middle of the bay, 0-0.60 cm/s. Bohai Bay is regional sea with strong tidal movements and the maximum possible tidal current velocity exceeds 100 cm/s. Kcy words： FVCOM; tide; tidal current; BohaiBay
