Abstract:

The height of the zone of intense turbulent heat exchange in the atmospheric boundary layer is analyzed from experimental data obtained with acoustic meteorological lidars (sodars), temperature profilometers, and sonic anemometers/thermometers. The main purpose of the work is to study the turbulent heat exchange under conditions of temperature inversions in the winter season. The results obtained at a territory with natural landscape and an urban territory in January – February 2020 are considered. Part 1 of the work describes the technique used to obtain experimental data and the statistics of temperature inversions in the boundary layer and heights of the layer of intense turbulent heat exchange. The relation of these heights and the corresponding air temperature gradients to the surface values of the wind speed and the vertical turbulent heat flux are analyzed in Part 2.

Keywords:
