Today’s Highlights
The 2025–2026 Iberian Peninsula saw exceptional landfalling atmospheric rivers whose moisture transport already matches early high-emission climate projections under SSP5-8.5. Using WRF simulations with ERA5 and CESM2 forcing, the study shows that subtropical Atlantic moisture sources were 5–20% stronger than projected under early SSP5-8.5 conditions, and precipitation over Atlantic-facing sectors significantly exceeded those projections. This finding suggests that the expected hydroclimate intensification from climate change is already manifesting in present-day extreme events.

Atmospheric rivers (ARs) drive winter hydroclimate extremes over the Iberian Peninsula (IP). This study evaluates whether exceptional landfalling ARs (LARs) between October 2025 and February 2026 displayed characteristics expected under early high‐emission forcing. High‐resolution WRF simulations forced by ERA5 and CESM2 under SSP5‐8.5 were used, using IPART for AR identification and FLEXPART‐WRF for moisture tracking. The simulated LARs reached vertically integrated water vapor transport magnitudes matching, and locally exceeding, those under the early SSP5‐8.5 climate response by 10%–15%. Mid‐tropospheric trough–ridge patterns enhanced zonal flow and long‐range moisture advection. Subtropical Atlantic moisture sources were 5%–20% stronger than simulated under the early SSP5‐8.5 response. LAR‐related precipitation over Atlantic‐facing IP sectors also matched or significantly exceeded (p < 0.05) early SSP5‐8.5 levels. These results suggest that present‐day extreme ARs can generate moisture transport and hydrological impacts comparable to early transient high‐emission projections.
