Temperature regime of the atmospheric boundary layer over Siberia

Abstract

The work presents an analysis of the air temperature distribution in the atmospheric boundary layer (ABL) over Siberia, estimated from the observations of 24 aerological stations for 1981−2020. It is shown that on average per year, as well as in winter, spring and autumn, the ABL temperature decreases in the northeast direction in Siberia. In summer, there is a zonal temperature distribution: a decrease from south to north. In winter, there are temperature inversions in the ABL throughout Siberia. In spring, temperature inversions are observed in the polar areas of Siberia, subpolar latitudes of Western Siberia and central regions of Eastern Siberia, in autumn there are ones in temperate and subpolar latitudes of Eastern Siberia.
