Short Summary

This study analyzes long-term precipitation trends in the Mediterranean region from 1950 to 2024 using ERA5-Land data, revealing significant regional variations in precipitation frequency and intensity.

Objective

• To analyze and quantify long-term trends in precipitation indices (frequency, intensity, and persistence) across the Mediterranean region to assess the impacts of climate change.

Study Configuration

• Spatial Scale: Mediterranean region.
• Temporal Scale: 1950–2024.

Methodology and Data

• Models used: Mann-Kendall test (trend detection) and Sen's slope estimator (trend quantification).
• Data sources: ERA5-Land high-resolution reanalysis dataset.

Main Results

• Heavy precipitation days (R10 mm): Decreased by approximately 2 days per decade in the western Mediterranean, while increasing by approximately 0.5 days per decade in the northeastern Mediterranean.
• Total annual precipitation (PRCPTOT): Observed declines of up to 60 mm per decade in specific areas.
• Maximum one-day precipitation (Rx1day): Increased by up to 3 mm per decade in localized regions.

Contributions

• Provides a comprehensive, high-resolution assessment of precipitation dynamics in a climate hotspot, offering quantitative evidence of the divergent precipitation trends between the western and northeastern Mediterranean.
