| 摘 要： | 基于有限体积法海洋数值模型(FVCOM),对渤海当前水深岸线状况下的潮汐潮流进行了数值计算。模式采用不规则三角形网格,较好地提高了黄河口处网格分辨率,模拟了渤海海域K1,O1,M2和S2四个主要分潮。利用渤海沿岸19个验潮站的资料对模拟结果进行了验证,K1分潮振幅绝均差2.39 cm,迟角绝均差4.36°,O1分潮振幅绝均差1.40 cm,迟角绝均差4.29°,M2分潮振幅绝均差为3.55 cm,迟角绝均差为5.69°,S2分潮振幅绝均差1.72 cm,迟角绝均差8.86°,结果显示各分潮模拟结果合理,较真实地反映了渤海海域四个分潮传播情况。 |

| Abstract: | Based on the finite-volume coastal ocean numerical model (FVCOM), we simulated K1, O1, M2 and S2 tidal constituents in the Bohai Sea by new coastline and topography. It can fit well with the shoreline in the Yellow River Estuary by using irregular triangle meshes for the model. Compared with the observation data obtained from 19 stations, we found that the result is reasonable to reflect the tidal transmission. For K1, the mean absolute difference of the amplitude is 2.39 cm, the mean absolute difference of the phase-lag is 4.36°. For O1, they are 1.40 cm and 4.29°. For M2, they are 3.55 cm and 5.69°. For S2, they are 1.72 cm and 8.86° respectively. |
