Extreme temperature inversions in the planetary boundary layer

Abstract

Experimental data on air temperature inversions in the planetary boundary layer are analyzed with the emphasis on events characterized by wide temperature differences between inversion boundaries. Temperature profiles measured in 2020-2021 with MTP-5 meteorological temperature profilometers at two observation sites located in southwestern Siberia (Tomsk) are used. The correlation between the inversion intensity and the wind direction in the atmospheric surface layer is touched.
