Numerical study of the stability and destruction of atmospheric temperature inversions under various meteorological conditions

Abstract

Some scenario calculations of the local atmospheric circulation in the Krasnoyarsk city and its visinity are carried out based on a mesoscale non-hydrostatic model of atmospheric dynamics. To simulate the mesoclimate of the area, the processes of formation and evolution of near-surface and elevated temperature inversions are studied. The results of the calculations show the behavior of inversion layers in the urban atmosphere due to of interaction of the large-scale atmospheric fields and the orographic and thermal features of the underling surface.
