Vertical distribution models of atmospheric structure constant of refractive index

The atmospheric structure constant of refractive index is an important parameter of denoting atmospheric turbulence, it was measured continuously in Hefei using QHTP-2 micro-thermal meter. The vertical profile of atmospheric structure constant of refractive index in Hefei（0～25 km）is investigated by analysis of experimental data,and the vertical atmospheric structure constant of refractive index model of atmospheric structure constant of refractive index in Hefei is gained based on Hufnagel-Valley model. It is found that the vertical profiles of atmospheric turbulence in Hefei have obvious daily and seasonal diversification. Atmospheric turbulence reduces with random fluctuation as height increases, it has obvious jumping configuration; upper air turbulence model in Hefei preferably acco
