摘　　要：针对复杂海洋中尺度现象模拟仿真的技术难题,利用区域海洋环流模式ROMS,通过模式的网格构建、地形处理以及模式的初始场和强迫场处理技术,构建出一套涡分辨率南海区域海洋环流模式。通过模式模拟结果与卫星遥感实测资料等对比,发现该模式能够较好地模拟出南海涡旋及其引发的海温异常等海洋中小尺度过程,说明该模式可作为研究复杂海洋中尺度现象影响海军武器装备效能的环境数值仿真手段。In view of the problem of the simulation for the ocean mesoscale phenomena,the advanced ocean circulation model ROMS is used to develop a eddy-resolving regional ocean circulation model in the South China Sea,based on the construction of model grid and topography,and the selection of model initial and forcing fields.Compared to the satellite remote sensing data,the simulation results can reproduce the eddy field and their associated mesoscale to submesoscale ocean temperature anomalies well.This shows that the model can be used as a numerical ocean environment testbed for the simulation of the effects of ocean mesoscale processes on the naval equipments.
