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。

Numerical simulation of tide in the Bohai Sea based on the finite-volume coastal ocean numerical model (FVCOM)

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.
