摘　　要：目前,国内外大尺度天气预报数值模式已经取得很大成就,如在预报地面气旋系统的移动和发展等方面。然而,这些模式的铅直分辨率一般不高,通常不包括边界层的动力过程,因而,在预报海面风场上,数值天气预报模式还没有令人满意的效果。目前所用的边界层预报模式尽管具有较高的水平分辨率和垂直分辨率,但要求大量的计算和资料,很难用于日常业务预报;另一种边界层诊断模式。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.
