文摘	依据Tatarski大气光学湍流参数化方案,利用数值天气预报模式(WRF)模拟了高美古、茂名、乌鲁木齐等典型地区高空大气光学湍流廓线。并将高美古和茂名使用温度脉动仪实测的光学湍流与其对应的模拟数据做了对比,结果表明,模拟的光学湍流廓线与实测的光学湍流廓线吻合得较好,相关性在76%左右。高美古和茂名的对比验证结果表明,利用WRF模拟高空大气光学湍流的方法是可行的,模拟得到了乌鲁木齐高空大气光学湍流廓线。结合这3个典型地区的气候特点,分析了不同气候类型下光学湍流的特征和变化趋势。
其他语种文摘	Based on the optical turbulence parameterization of Tatarski theory,the optical turbulence profiles of upper air at Gaomeigu,Maoming and Urumqi are simulated by numerical weather research and forecasting(WRF) model.Simulation results are compared with optical turbulence measured by micro-thermometer at Gaomeigu and Maoming.It shows that the simulated and measured optical turbulence profiles are consistent well,and the correlation coefficient is up to 76%.The verified results at Gaomeigu and Maoming show that the method by using WRF model to simulate optical turbulence is feasible,and the optical turbulence profile of upper air at Urumqi is obtained.Combined with the climatic features of these three typical areas,characteristics and variation trend of upper air optical turbulence under different climate types are analyzed.
