Short Summary

This study investigates the spatiotemporal variability of flash droughts in Greece from 1990 to 2024 using ERA5-Land root-zone soil moisture data. It reveals distinct regional patterns in flash drought characteristics, including frequency, duration, and recovery, providing a data-driven framework for water management and adaptation strategies in Mediterranean agriculture.

Objective

• To examine the spatiotemporal variability of flash droughts in Greece for the period 1990–2024.

Study Configuration

• Spatial Scale: Greece, at 0.25° resolution.
• Temporal Scale: 1990–2024, using 5-day (pentad) intervals.

Methodology and Data

• Models used: Percentile-threshold approach for flash drought detection; innovative empirical classification framework founded on decline and recovery rates.
• Data sources: ERA5-Land root-zone soil moisture (0–100 cm).

Main Results

• Central Greece and Thessaly exhibit the highest frequency and longevity of flash droughts.
• Western Greece, Peloponnese, and Western Macedonia are characterized by rapid flash drought development but intense recovery.
• An empirical classification framework identified that Mild Fast Recovery events prevail in northern and central Greece.
• Intense but Recovering events dominate in western and southern Greece.

Contributions

• Offers new perspectives on how flash droughts impact soil–water availability and agricultural resilience in the Mediterranean climate.
• Provides a data-driven platform to aid sustainable water management, early warning systems, and adaptation strategies for Mediterranean agriculture under climate variability.
• Introduces an innovative empirical classification framework for flash drought events based on decline and recovery rates.
