Forecast upper air optical turbulence based on weather research and forecasting model

Forecasting upper air optical turbulence has important significance in optical engineering applications. This paper introduces the running processes of Weather Research and Forecasting Mode (WRF), mode installation, and simulation parameter settings. Combine with optical turbulence parameterization schemes, the atmospheric optical turbulence intensity profile was forecasted and compared with the measured data by balloons. The result shows that: the forecasted atmospheric optical turbulence intensity profiles are in line with the general characteristics and regularity of the upper air optical turbulence, but their shapes have some differences. the analysis on the causes of the differences is made, which shows it is necessary to further modify the forecasting model and the calculation of atmospheric optical turbulence.
