摘　　要：利用非结构化网格有限体积方法的海洋模式FVCOM建立了一个高分辨率的渤海潮汐潮流模型,通过与历史结果和实测资料的对比证明了模型的可靠性,然后描述了渤海海峡的潮波运动状况,以模型垂向平均流速为基础对渤海海峡的潮流能进行了估算。结果表明,渤海海峡的潮流以往复流为主;最大可能流速的最大值出现在老铁山西角,为3.3m/s;对于平均能流密度大于100W/m2的海区,老铁山角附近达515.9km2,比登州水道大一个量级,而登州水道比其余诸水道均大一个量级。A high resolution tide current model of the Bohai Sea is built based on an unstructured grid, fi- nite volume method ocean model （FVCOM）. The results from the model agree well with previous studies and field data. The tidal waves in the Bohai Strait is described and the tidal stream enering is estimated based on the vertically averaged currents derived from the model. The results show that the tidal current is mainly rectilinear and the maximal value of the possible maximum velocity of the tidal current reaches 3.3 m/s at the west of the Laotieshan Cape. The sea area where the power density is larger than 100 W/m2 can reach to 515.9 km2 near the Laotieshan Cape. This is one order greater than that in the Dengzhou Chan- nel, while the Dengzhou Channel is one oder larger than the rest channels.
