【摘要】 基于河口、陆架和海洋模式 (ECOM模型 ) ,引入干湿网格法模拟潮滩涨落的改进 ,建立了渤海湾三维变动边界潮流模型。该模型网格采用为 4 80 m× 6 2 0 m,垂向 4层 ,充分考虑渤海湾潮滩广阔的特点。计算结果与实测值比较符合良好 ,较好地刻画出渤海湾 M2 分潮潮流场的时空分布特点。更多还原

【Abstract】 A 3 D numerical tidal model to simulate M 2 tidal current field with a variable boundary in Bohai Bay is established. The model is based on an international 3 D coastal ocean circulation model (ECOM model), and is modified by incorporating dry wet grid technology to simulate flooding and ebbing in tideland. The grid is 480m×620m, and 4 lays in vertical are used. The shallow water areas and tidal areas in the Bohai Bay are taken into account. The computed results match well with the observations. It gives good temporal and spatial distribution of M 2 tidal current in the Bohai Bay.更多还原
