The atmospheric pattern making Europe's summers drier with each decade
Leipzig University researchers found that more frequent, persistent high-pressure systems account for 55% of the observed increase in European summer drought severity.
Europe's summers have grown markedly drier and hotter, and Leipzig University researchers have now pinpointed the main mechanism. High-pressure systems are occurring more frequently and lasting longer, replacing the weather patterns that normally cycle through the continent.
This atmospheric shift accounts for around 55% of the observed summer drought trend across Europe.
Why it mattersPinpointing atmospheric circulation as the dominant driver helps Europe plan drought responses and water policy around predictable weather patterns, not just long-term warming.
