The aim of the study is to analyze climatic changes within the arid landscapes of the North Caucasus using observational data from the reference meteorological network, as well as spatial interpretation of the results using GIS technologies. Materials and methods. To assess climatic changes in arid landscapes, data from the Divnoe, Roschchino, Naurskaya, Makhachkala and Derbent meteorological stations were used for the period from 1961 to 2020. Material processing was carried out using statistical methods (Exсel). The results were mapped using GIS technologies (MapInfo and ArcGIS). Results. Analysis of the thermal regime of the arid landscapes of the North Caucasus for the period from 1961 to 2020 showed that climatic changes proceed according to the scenario of an increase in annual air temperature. Precipitation in the north- and southwestern areas of semi-desert landscapes is decreasing, while in the southeastern areas it is increasing. Against the background of an increase in air temperature and a decrease in precipitation, the value of the hydrothermal coefficient is also decreasing. Thematic maps obtained from the analysis of the hydrothermal coefficient illustrate the increase in the area of semi-deserts and dry steppes in 2011-2015. In comparison with 1991 -1995. Conclusions. Despite the decrease in the hydrothermal coefficient for all areas of the semi-desert landscapes of the North Caucasus, the hydrothermal coefficient value remains within the limits typical for semi-deserts and dry steppes.
