This paper describes the use of a self-made meteorological radiosonde for turbulence analysis to measure profiles of the turbulence parameter Cn2 and meteorological parameters such as temperature, wind speed, and wind direction in Lhasa, Tibet. The trends of variation of turbulence intensity and meteorological parameters with height are analyzed. A comparison of the turbulence characteristics in the morning and evening reveals that a strong turbulence layer appears at 8-15 km at both these durations, but the turbulence intensity above 8 km in the morning is greater than that in the evening. Furthermore, based on the Hufnagel-Vally 5/7 model, the Cn2 Lhasa model is fitted using the statistical average of all radiosonde data. The statistical analysis results show that the Cn2 Lhasa model can effectively estimate the turbulence intensity above Lhasa. Finally, a comparison of the radiosonde data of Lhasa and Gaomeigu reveals that the wind speed in Lhasa is lower and favorable for astronomical observations, but the turbulence in Lhasa is stronger and reduces the quality of astronomical observations. These results provide a foundation for the study of turbulence profiles, observatory site selection, and support for the application of electro-optical engineering in Lhasa.
