【摘要】 将河口、陆架和海洋模式应用于胶州湾 ,建立其三维潮流数值模型。计算结果与实测值相比 ,吻合良好 ,重现了胶州湾M2 分潮的时空分布。模拟结果表明 :水平流速从表层到底层逐渐衰减 ,临近海底时 ,衰减迅速 ;而垂向流速变化规律与之相反 ,底层最大。最大垂向流速位于水深梯度较大处 ,说明地形的强烈起伏 ,使潮流大幅度地爬坡或落降 ,是产生较大垂向速度的重要因素更多还原

【Abstract】 Applicalion of a numerical model of estuary,shelf and sea to simulate M 2 tidal current field of Jiaozhou Bay was made. The computed results match well with the observed ones. It shows well the temporal and spatial distribution of M 2 tidal current. The vertical structure of the tidal current field was studied in this paper. With increasing water depth, horizontal velocity decreases, especially rapidly near the bottom. On the contrary, vertical velocity have a different trend with water depth and near the sea bottom. It shows that the vertical velocity is significantly affected by the rising and falling topography.更多还原
