Abstract
Using a new method for determining the parameters of wind turbulence from the spectra of the vertical wind speed measured by a pulsed coherent Doppler lidar (PCDL), an experiment was carried out in 2020 on the coast of Lake Baikal as part of the study of turbulence and internal gravity waves (IGW) in the atmospheric boundary layer (ABL). The article presents the results of this experiment and analyzes the spectra and lidar estimates of the variance of the vertical wind speed and the turbulent energy dissipation rate obtained from the measurements of the Stream Line PCDL in the presence of a low-level jet and IGW in the ABL.
