采用“油粒子”模型,模拟溢油在海洋中的漂移扩散运动,将海流、波浪和风场的模拟结果作为溢油漂移计算的外强迫,来驱动溢油漂移模型,计算其漂移路径.把计算的溢油漂移结果与地理信息系统等平台相结合,建立了渤海海域应急预测预警系统.本文作为该系统研制中的一部分,主要介绍了海流数值计算模型、波浪数值计算模型、风场数值计算模型和溢油预测模型的研究工作.%The "oil particle" model is adopted to simulate the drift and diffusion of the oil spill in ocean. The simulative results of the current, wave and wind field are taken as the outside force for the computation to drive the oil spill drift model, and the drift trace is consequently calculated. The Emergency Warning& Predicting system of Bohai Sea is established by combining those computed oil spill results and several platforms like GIS. As a part of this system, this paper introduces the research status of the numerical computing models of current, wave and wind field, and also the oil spill predicting model.
