Abstract
The dynamics of meteorological parameters in Siberia and the Altai–Sayan region in the 20th–21st centuries are analyzed. Significant trends characterizing the dynamics of the average temperature, precipitation, and standardized precipitation evapotranspiration index (SPEI) are revealed. Growing wildfire frequency in the area under study since the end of the 20th century has been detected. The annual variation of wildfires has a phase coincidence with the dynamics of mean temperatures, positively correlates with climate dryness, and negatively correlates with averaged precipitation data. An abrupt increase in wildfire frequency has been observed in the late 20th–early 21st centuries. The spatial redistribution of wildfires in the Altai–Sayan region in the early 21st century is revealed.
