Capabilities of a Turbulent BSE-Lidar for the Study of the Atmospheric Boundary Layer

In order to study the capabilities of a turbulent lidar, an experiment was carried out with a BSE-4 system, a meteorological measuring system, and an MTP-5 temperature profiler. The profile of the structural parameter of the refractive index was determined with the lidar with a 15-s interval up to an altitude of 2 km. The dynamic turbulence strength was measured over rough terrain when the wind increased. Lidar operation under buoyant convection conditions allowed us to observe the rise of thermals and the formation of Cu clouds in the atmospheric boundary layer. Under the conditions of cellular convection, the lidar recorded quasi-periodic oscillations of (Benard cells), which represented a stationary wave. Under stable temperature stratification, when the Richardson number was less than 1/4, the turbulent lidar detected a Kelvin–Helmholtz wave.
