Overview
- The peer‑reviewed analysis appears March 13, 2026 in Weather and Climate Extremes.
- Exceptionally warm sea‑surface temperatures in the Mediterranean and the North Atlantic increased the event’s precipitation by as much as 40%.
- North Atlantic warmth alone accounted for about a 15% boost in intensity, in what authors describe as the first explicit evaluation of that basin’s role.
- Modeling traced two long‑range moisture streams feeding the storm, with Mediterranean waters about 3°C above normal and North Atlantic anomalies up to roughly 2.5°C near Greenland.
- The authors call for wider deployment of global, high‑resolution tools such as Destination Earth’s Climate Adaptation Digital Twin to improve anticipation and adaptation, noting the floods caused more than 200 deaths and multi‑billion‑euro damage.
