| 摘 要： | 基于采用无结构网格和有限体积方法的FVCOM陆架模式,考虑8个主要的天文分潮,建立胶州湾三维高分辨率数值模型来重现和研究其潮汐潮流变化状况。与实测资料对比验证表明,模拟结果与实测值吻合较好。在此基础上,根据模拟结果计算得到了较以往更为精细的同潮图和潮汐、潮流、余流分布特征。研究结果揭示,最大可能潮流和最大余流都发生在团岛附近,流速分别可达2.14和0.43 m/s;除了湾口附近前人报道过的4个余流系统外,还在中部首次揭示了2个相对较弱的余流系统;潮流能通量在内外湾口呈"左进右出"的结构;胶州湾的平均纳潮量为8.31亿m3;染色试验表明,胶州湾30 d的水交换率为36.8%。

| Abstract: | Based on an unstructured grid and finite-volume costal ocean model(FVCOM),which includes 8 major constituents,a three-dimensional high resolution model is constructed in the Jiaozhou Bay to reproduce the tide and tidal current.Comparisons between observations and numerical modeling indicate that the computed results agree well with the measured values.According to the numerical simulation,more elaborate co-tidal lines are obtained as well as the distributions of tide,tidal current,residual current.The maxim... |
