Preliminary application of Air-Wave-Sea coupling model in Bohai sea

In view of the important practical needs of marine forecasting and marine production in the Bohai Sea port, this paper constructs a regional high-resolution coupled forecasting model of sea air waves to carry out 5-day marine forecasting. The resolution of ocean and wave models is higher than 1km, and the resolution of the inner layer grid of the atmospheric model is 3km. Compared with the international advanced model HYCOM, it is found that the simulation results of the high sub regional coupling model are obviously better than those of HYCOM, its results clearly shows the flow field and tidal current characteristics, which are consistent with the observation results; The spatial modes of SST are consistent with HYCOM. The results of current and SST indicate that the prediction results of the coupled model are reliable and better than those of HYCOM.
