Short Summary

This study analyzes precipitation trends in Northern Ukraine, finding a general shift toward aridity during the summer and specific winter months, contrasted by increased precipitation in May and October.

Objective

• To evaluate changes in precipitation patterns and moisture anomalies in the northern regions of Ukraine by comparing two climatological periods (1961-1990 and 1991-2020) and analyzing the most recent decade (2011-2020).

Study Configuration

• Spatial Scale: Northern Ukraine (Zhytomyr, Kyiv, Chernihiv, and Sumy regions), based on 17 meteorological stations.
• Temporal Scale: 1961–2020 (with specific focus on 1961-1990, 1991-2020, and 2011-2020).

Methodology and Data

• Models used: Comparative statistical analysis of climatological indicators.
• Data sources: Average monthly precipitation data from 17 meteorological stations.

Main Results

• Seasonal Trends: A tendency toward dryness was observed in April, summer (peaking in August), and from November to January (minimum in January). Conversely, precipitation increased in May, October (increases $\ge 20$ mm in parts of Kyiv and Chernihiv), February-March, and September.
• Recent Decade (2011-2020):
  • Precipitation deficits occurred in 43-53% of all months.
  • Warm season: All 17 stations showed a drought tendency (49-61% of months).
  • Cold season: Normal or excess moisture predominated, except in the Kyiv region.
• Extremes: Significant moisture excesses (200-400% of the norm) were recorded in October, December, and January-February.
• Causality: Precipitation anomalies were driven by large-scale circulation processes: southern and western cyclones caused intense precipitation, while blocking processes caused droughts in both summer and winter.

Contributions

• Provides a high-resolution regional assessment of precipitation variability in Northern Ukraine, distinguishing between the general trend toward aridity in the south/east and the more complex, variable moisture patterns in the north.
