| Abstract: | Numerical study of the Bohai Sea circulation was carried out based on three-dimensional primitive equation ocean model.The model was easy to fit the irregular coastal boundary of the Bohai Sea with the unstructured triangular grid.The simulated tides,tidal current and thermohaline field were well verified by observation data.The circulation of Bohai Sea during winter and summer and their relations between tides,wind,river discharge as well as the heat flux were studied by means of Lagrangian trajectory.It s... |
