Abstract
The results of experimental studies of the atmospheric boundary layer in the coastal zone of Lake Baikal using a coherent Doppler wind lidar and a temperature profiler are presented. Temporal-altitude distributions of the wind speed, temperature, and the Richardson number are derived. The parameters of atmospheric waves in a stably stratified boundary layer are determined. Variations in the dissipation rate of the kinetic energy of turbulence, the variance of the fluctuations of the radial velocity, and the outer turbulence scale during the low level jets and internal atmospheric waves in the stable boundary layer and their relation to variations in the Richardson number are analyzed.
