Abstract
Model estimates of the altitude of the mixing layer in the atmospheric boundary layer under conditions of temperature inversions are compared with the experimentally estimated altitude of the layer of intense turbulent heat exchange. The experimental data are received with the temperature-wind system consisting of meteorological acoustic lidar (sodar), meteorological temperature profilometer, and ultrasonic anemometers-thermometers. It is shown that under conditions of temperature inversions, the altitude of the mixing layer calculated by the model equations is usually much smaller than the altitude of the layer of turbulent heat exchange.
