Analysis of climate drivers reveals complex interactions affecting hydroclimatic patterns in the Mediterranean region, highlighting the role of wind speed.

Key Points

This research aims to explore the climate drivers affecting hydroclimatic variability in the Mediterranean region using ERA5 reanalysis data.
Analyzed ERA5 reanalysis data from 1950 to 2024
Examined trends in temperature, precipitation, evaporation, wind, and sensible heat
Distinguished effects between land and sea domains
Performed correlation analyses to assess interrelations among climate variables
Applied Hurst–Kolmogorov stochastic framework to identify long-term variability
Temperatures increased by 0.03 °C year−1 over land and 0.015 °C year−1 over sea, indicating a strong warming signal
Evaporation over land declines slightly while sea shows a minor increase, showing strong interannual variability
Sensible heat flux increases over land but decreases over sea, revealing differing energy-partition regimes
Precipitation exhibits no significant long-term change despite a warmer, moister atmosphere
Wind speed has a stronger impact on evaporation and precipitation than temperature.
