摘　　要：建立了一个多开边界群岛海域溢油模拟的三维水动力模式 ,并在舟山定普港域作了模拟和预报试验 .模式采用高分辨的水平曲线正交网格和 2 .5阶湍流闭合模型 ,通过有限差分隐式 /半隐式求解具有初、边值条件的三维原始动力方程组 .初步试验表明 ,模式重视了港域内许多重要的流体动力学特征 ,能模拟或预报海域内三维潮流、风生流及其相互作用 。A hydrodynamical model for oilspill simulation in archipelagic waters with multiple open boundary conditions is set up and simulation/forecast tests in Zhoushan dingpu Port are performed.A horizontal high resolution orthogonal curvilinear grid system and a turbulence closure submodel to the 2.5 power are incorporated in the model.The three dimensional (3D) primitive equation sets together with their boundary conditions are solved by finite difference technique according to implicit/semi implicit scheme.Preliminary study shows that the model can reproduce the most of important hydrodynamic features in the waters of interest,simulate/forecast 3D tidal current,wind driven current and their interaction,and thus provide a real time flow field for oilspill simulation.
