Short Summary

This study analyzed long-term climatic changes (late 20th to early 21st century) in the Central Russian Upland, revealing significant warming and a decrease in moistening conditions during the warm season due to contrasting temperature and precipitation trends.

Objective

• To analyze long-term changes in a complex of climatic variables and moistening conditions on the south of the Central Russian Upland of the East European Plain from the last decades of the 20th century to the first decades of the 21st century.

Study Configuration

• Spatial Scale: Regional (South of the Central Russian Upland of the East European Plain).
• Temporal Scale: Long-term (Last decades of the 20th century – first decades of the 21st century, specifically 1980-2020 for some trends).

Methodology and Data

• Models used: Not specified in the provided text.
• Data sources: Observational data (climatic parameters).

Main Results

• The annual average temperature increased by 2.1 °C between 1980 and 2020.
• Absolute values of the temperature of the warmest and coldest quarters, and accumulated temperature over the period with values above 10 °C, increased significantly, showing positive, statistically significant trends.
• Annual precipitation and precipitation during the warmest quarter showed a weak negative trend, while precipitation of the coldest quarter showed an increasing trend.
• Contrasting changes in temperature and precipitation led to a decrease in moistening indicators during the warm season. The hydrothermal coefficient decreased by more than 18%, and the drought index increased by approximately 18%.
• Spatial changes in most climatic parameters are associated with a shift in isolines to the north or northwest.

Contributions

• Provides objective, long-term data on regional climatic and moistening changes in the south of the Central Russian Upland.
• Identifies contrasting trends between heat and moisture supply, leading to significant drying during the warm season.
• Documents spatial shifts in climatic isolines within the region.
