Height of the Mixing Layer under Conditions of Temperature Inversions: Experimental Data and Model Estimates

Results of comparing model estimates of the mixing layer height in the boundary layer of the atmosphere under conditions of ground inversions of air temperatures with experimental estimates of the height of the intense turbulent heat exchange layer are presented. Experimental data necessary for these estimates are obtained using a temperature-wind complex including a meteorological acoustic locator (sodar), a meteorological temperature profiler, and ultrasonic anemometer-thermometers. It is shown that the mixing layer height calculated by the model formulas under conditions of ground inversions of temperature is as a rule significantly less than the height of the turbulent heat exchange layer.
