PRELIMINARY RESULTS OF SOUNDING OF THE WINTER BOUNDARY LAYER OF THE ATMOSPHERE WITH WIND AND TURBULENT LIDARS
Abstract and keywords
Abstract (English):
An experiment using turbulent and Doppler wind lidars was conducted in Tomsk from December 2024 to April 2025. One wind lidar operated at zenith, and the other two, together with turbulent lidars, performed sounding at a small angle in the north and northwest directions. The purpose of the experiment was to study the capabilities of the equipment for studying the structure and dynamics of mesoscale eddies in the atmospheric boundary layer. Observations were made in the cold season, when the temperature stratification of the boundary layer is stable. The main attention was paid to atmospheric waves and organized (coherent) structures. The readings of the turbulent lidars were compared with the data of wind lidars, a temperature profiler, and meteorological parameters.

Keywords:
