Abstract
The ranges of changes in the parameters of wind and temperature (refractive) turbulence estimated from lidar data, corresponding to the intensity of aircraft shaking severity caused by turbulence in the free atmosphere at flight altitudes, are determined. It is shown that both the estimation of the variance of the radial velocity measured by a coherent lidar in the direction of flight, and the determination of the structural constant of the refractive index from the data of the lidar, which measures the intensity of refractive turbulence in flight direction, make it possible to judge the potential danger of aircraft shaking severity in clear air turbulence zones ahead of the aircraft.
