摘要：

利用有限元方法的ADCIRC(Advanced Circulation Model)海洋模式,建立了渤海高分辨率的二维潮汐潮流模型,模式结果与实测资料吻合良好。模式成功模拟出了M2分潮在渤海的2个无潮点和3个圆流点,位置与前人的研究结果基本一致。M2分潮流在渤海中央为顺时针旋转的旋转流,在辽东湾、渤海湾和莱州湾基本为往复流。M2分潮的潮汐和潮流的振幅都表现为辽东湾最大,莱州湾最小。M2分潮的潮致余流主要表现在近岸和岛屿附近,最大可达10 cm/s。

With the application of ADCIRC,a high resolution of two-dimensional tidal model in the Bohai Sea was built up,and the model results are conformable to the field observations.Two amphidromic points and three tidal current non-phase points for M2 tide were successfully modeled,whose positions were basically conformable to the previous studies.The style of the M2 tidal current is rotary current in the middle of the Bohai Sea,while rectilinear current in the Liaodong,Bohai and Laizhou Bay.The amplitude of the M2 tide and tidal current are largest in the Liaodong Bay,while smallest in the Laizhou Bay.The M2 tidal reduced residual current is only evident along the coastal region and at the area near the islands,which can reach as much as 10 cm/s.
