A coupled ice-ocean model for the Bohai Sea Ⅰ. Study on model and parameter

According to the earlier international studies on the coupled ice-ocean model and the hydrology,meteorology,and ice features in the Bohai Sea,a coupled ice-ocean model is developed based on the National Marine Environment Forecast Center's (NMEFC) numerical forecasting ice model of the Bohai Sea and the Princeton ocean model (POM).In the coupled model,the transfer of momentum and heat between ocean and ice is two-way,and the change of ice thickness and concentration depends on heat budget not only at the surface and bottom of ice,but also at the surface of open water between ices.The dynamic and thermodynamic coupling process is expatiated emphatically.Some thermodynamic parameters are discussed as well.
