Abstract
Aim. The purpose of this work is to study the dynamics of air temperature and soil temperature in different soil zones of Western Siberia in relation to modern climate change.
Methodology. Based on long-term data from 259 weather stations located on the territory of Western Siberia, an analysis of air and soil temperature distribution and their changes within the areas of nine soil zones (subzones) for the period 1951–2020 was carried out using geographic information systems.
Results. It is shown that in the modern period in all soil zones of Western Siberia there is a climate change towards warming, which is characterized by zonality. The most significant increase in air temperature in the last decade is observed in the north of Western Siberia, especially in the arctic tundra, subarctic tundra and northern taiga subzones, and it becomes less noticeable as we move southward to the steppe zone. Modern warming leads to a change in the temperature regime of soils in Western Siberia and, as a result, a shift of soil-climatic zones to the north. Mapping models of the average annual air temperature for each decade of the period 1951–2020 and the climatic norm 1961–1990 were created, as well as mapping models of air temperature change (average annual and by seasons of the year).
Research implications. The revealed changes in the atmospheric and soil climate must be taken into account when assessing climate risks and developing agrotechnical measures for growing crops, as well as measures to protect infrastructure facilities in the cryolithozone.
