摘　　要：基于MM5V3中尺度天气预报模式建立了低空大气波导模拟平台,利用FNL再分析数据与GTS数据对东海海区大气波导分布进行了七个月的模拟。通过那霸、石垣和南大东岛3个站点的实测结果与模拟结果的比较,计算了波导发生的模拟准确率,统计分析了波导随时间的变化。结果表明,MM5V3模式能够较好的模拟出大气波导的产生和变化,尤其是模拟范围广、强度大的波导效果更好。A platform of simulating atmospheric ducts is established with meso-scale weather forecasting model MM5V3.The distribution of atmospheric ducts over the East China Sea is simulated for 7 months by using FNL reanalysis data and GTS data.The accuracy ratio is calculated by comparing the modeling results with the obser-vations in NAZE,ROIG and ROMD.It＇s shown that MM5V3 could successfully reproduce the formation and movement of atmospheric duct,especially for those with larger range and high intensity.
