Abstract: Research of atmospheric turbulence is the actually investigation of atmospheric refractive index. The atmospheric structure constant of refractive index $C_n^2$ is an important parameter of denoting atmospheric turbulence. Using new micro-thermal meter, the atmosphere temperature, pressure and $C_n^2$ are measured in Hefei of Anhui, Beijing and Kuerle of Xinjiang by analyzing experimental sounding data in different representative area, the statistical characteristics of vertical distribution of atmospheric parameter are investigated to offer necessary data for atmospheric turbulence model. Using Hufnagel-Valley model and NOAA model, the atmospheric turbulence models in different representative area are obtained on the basis of actual upper air data. Method evidence and valuable reference will be provided for research on atmospheric turbulence mode in other typical area.

Key words: atmospheric optics, atmospheric turbulence, atmospheric structure constant of refractive index, variance profile, models
