Short Summary

This study assesses the spatio-temporal variability and trends of climate conditions across the Czech Republic using observations from nine stations over half a century (1973–2022). Results indicate predominantly moderate aridity in central and southwest regions, with increasing dryness in typically wet areas and decreasing aridity in some dry areas, providing critical insights for water-resources planning.

Objective

• To assess the spatio-temporal variability and trends of climate conditions, specifically aridity, across the Czech Republic's nine major river basins over a half-century period.

Study Configuration

• Spatial Scale: Czech Republic, focusing on nine major river basins (Upper and Lower Vltava, Berounka, Dyje, Upper and Middle Elbe, Upper Oder, Morava, and V´ah tributaries).
• Temporal Scale: Half-century (1973–2022).

Methodology and Data

• Models used: Innovative Trend Analysis (ITA), Mann–Kendall family tests. Two aridity metrics: UNEP index (computed from precipitation and potential evapotranspiration) and De Martonne index (computed from precipitation and temperature).
• Data sources: Observations from nine meteorological stations.

Main Results

• Predominantly moderate aridity (40th–60th percentiles for both indices) was found in central and southwest regions, including the Upper and Lower Vltava, Berounka, Dyje, and Upper and Middle Elbe basins.
• During spring, the Dyje and Lower Vltava basins exhibited semi-arid conditions (UNEP: 0.2–0.5) and Mediterranean conditions (De Martonne: 20–24), respectively.
• The eastern sector (Upper Oder and parts of the Morava and V´ah tributaries) showed a transition to wetter conditions (UNEP: 1.61–3.61; De Martonne: 94.94–238.21), indicating flood-prone areas.
• A consistent increase in dryness was observed in the typically wet Upper Oder basin, except during summer.
• A significant decrease in aridity was detected across all four seasons and annually in the dry-climate area of Lower Vltava.
• Abrupt shifts in aridity for the De Martonne index were identified in winter 2012 at Pˇribyslav and in summer 1989 at Praha Ruzynˇe.

Contributions

• Provides critical and innovative insights into the half-century spatio-temporal variability and trends of climate conditions across the Czech Republic’s nine major river basins.
• Supports adaptive water-resources planning, food security initiatives, and efforts to mitigate the cascading impacts of global change and the biodiversity crisis.
• Employs a robust analytical framework combining Innovative Trend Analysis (ITA) with Mann–Kendall family tests for a comprehensive assessment of aridity trends.
