Abstract
In the summer of 2015 for two weeks on the coast of Lake Baikal near Listvyanka we carried out experiments using a coherent Doppler lidar “Stream Line”. Place of the lidar measurements and atmospheric conditions contributed to a relatively frequent occurrence of internal gravity waves (in the form of quasi-harmonic oscillations of the wind vector components) in the atmospheric boundary layer. As a result of our analysis of this experimental data we have detected 6 cases of propagation of the gravity wave with the oscillation period of 6.5 min and 18 min (once) and 9 min (four cases). As a rule, the duration of gravity wave observation was around 45 min, but in one case the duration was approximately 4 hours.
