A Numerical Simulation of Extratropical Storm Surge and Hydrodynamic Response in the Bohai Sea
A hindcast of typical extratropical storm surge occurring in the Bohai Sea in October 2003 is performed using a three-dimensional (3D) Finite Volume Coastal Ocean Model (FVCOM). The storm surge model is forced by 10 m winds obtained from the Weather Research Forecasting (WRF) model simulation. It is...

| description | A hindcast of typical extratropical storm surge occurring in the Bohai Sea in October 2003 is
performed using a three-dimensional (3D) Finite Volume Coastal Ocean Model (FVCOM). The storm surge
model is forced by 10 m winds obtained from the Weather Research Forecasting (WRF) model simulation. It
is shown that the simulated storm surge and tides agree well with the observations. The nonlinear interaction
between the surge and astronomical tides, the spatial distribution of the maximum surge level, and the
hydrodynamic response to the storm surge are studied. The storm surge is the interaction of the surge and the
astronomical tides. The currents change rapidly during the storm surge and turn to be the unidirectional at
some places where the tidal currents are usually rectilinear. The results show that the local surge current
velocity in each depth, with a magnitude of the same order as the astronomic tidal currents, increases or
decreases rapidly depending on the relationship between the winds and current directions. Furthermore, the
current pattern gets more complicated under the influence of the direction of the winds, which might affect
sand movement in the coastal water of the Bohai Sea. |
