Weather Regime Diversity, Transitions, and Trends Using Hexagonal Self‐Organizing Maps
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.Abstract Persistent atmospheric circulation patterns, or weather regimes, strongly modulate surface weather and extremes, yet their internal diversity, transitions, and trends remain less understood for North America. We apply a self‐organizing map (SOM) framework to represent North American weather regimes using daily 500‐hPa geopotential height ...

The Emergence of a Human Fingerprint in the Boreal Winter Extratropical Zonal Mean Circulation
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The large‐scale atmospheric circulation plays an important role in regional climate. Recent studies have shown that poleward shifts in the Northern Hemisphere jet streams may be emerging, but the statistical significance and robustness are questionable.

Cultural Responses to Climate Change During the Late Holocene [PDF]
This study describes the effect of drought on past civilizations and peoples and their response as civilizations or cultures. The site includes four case studies drawn from New and Old World civilizations that document societal responses to prolonged ...

Dynamically‐Informed Extreme Event Attribution Using Circulation Imprints
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract We present a novel extreme event attribution approach, isolating dynamical from other contributions to changing extreme event probability. Event‐specific, multivariate circulation imprints are linked to impact‐relevant hazard indices in a flexible framework which we demonstrate for three recent high‐impact extreme events: the 2025 Los Angeles ...

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Climate change impacts include contributions from both anthropogenic forcing and internal (natural) climate variability. Large ensembles of Earth System Model (ESM) simulations have been used to quantify the influence of natural variability in climate change impact projections. However, such ensembles have high computational costs.

Projected Changes of Mesoscale Eddy Activity in Subantarctic Mode Water Formation Regions
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Subantarctic Mode Water (SAMW) plays a vital role in the uptake of heat and carbon, thereby regulating global climate. Mesoscale eddies affect mode‐water subduction and transport in the Southern Ocean. However, it remains unclear how SAMW‐related eddy activity will evolve under anthropogenic warming, because most state‐of‐the‐art climate ...

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract A persistent challenge in hydrological modeling is reliably transferring predictive skill across time and among basins that appear distinct based on conventional static attributes. Here we address this challenge by leveraging Google's newly released data set generated from the AlphaEarth Foundations model, providing 64‐dimensional satellite ...

Observed Tightening of Tropical Ascent in Recent Decades and Linkage to Regional Precipitation Changes [PDF]
, 2020 Climate models predict that the tropical ascending region should tighten under global warming, but observational quantification of the tightening rate is limited.
