Based on the features of limited sea areas and scale analysis methods, the orders of every term in the mesoscale meteorological models are estimated, and at the same time a wind field model of limited sea area is developed, for numerical simulation of marine dynamics phenomena such as waves tides and storm surges, particularly for application to forecasting of marine dynamical characteristics. Furthermore, the initialization methods for the wind field forecast were improved and the model was applied to Bohai sea for forecasting examination. The simulated results showed some details never obtained before and agreed well with observational data. The model has been used for forecasting of combine wave-tide-surge.
