Disentangling Anthropogenic Effects on Southern Hemisphere Circulation and Surface Climate: A Multi‐Model Large Ensemble Approach

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Southern Hemisphere (SH) circulation and surface climate changes are emerging in recent decades. For example, in most seasons, the SH Hadley cell edge and the eddy‐driven jet stream have shifted polewards, and the Southern Annular Mode (SAM) has trended towards its positive phase.

Weak Tropical Tropospheric OH Response to Idealized ENSO

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The hydroxyl radical (OH) is a key oxidant for methane. Previous studies suggest that OH exhibits interannual variability linked to the El Nino–Southern Oscillation (ENSO), but the sign, magnitude, and underlying mechanisms of this response remain uncertain.

Positive Association Between Coastal Sea Surface Temperatures and Humid Heat Stress on Nearby Land

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Large populations along Earth's coastlines are exposed to climate hazards including extreme humid heat. Considering observed coastal ocean warming and increased coastal marine heatwave (MHW) activity, we seek to uncover if, how, and where coastal ocean temperatures are linked with heat and humidity on land nearby.

Sea Surface Temperature Feedbacks and Convective Organization Mediate the Tropical Circulation Response to Aerosols

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Coupling between aerosols, atmospheric circulation, and tropical sea surface temperature (SST) patterns is an important part of anthropogenic influence on climate but is not well understood. Using idealized, cloud‐resolving simulations with a slab ocean, we examine the hydrologic and circulation responses to uniform and spatially varying ...

Pacific Warming Pattern Discrepancy Linked to Spurious Rainband in Climate Models

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The distinctive pattern of observed Pacific surface temperature trends, with cooling in the east and intensified warming in the west, departs from the more uniform warming anticipated by climate models. The apparent inability of climate models to simulate this warming pattern limits our ability to understand why it is occurring and to predict ...

Momentum Decoupling Drives Low‐Wind Events During Heatwaves in China: A Hybrid Explainable Machine Learning and Dynamical Modeling Approach

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Compound heatwave and low‐wind (HW‐LW) events increasingly threaten China's energy security. Analysis of 2000–2023 data reveals these compound extremes account for 18.5% of total heatwaves, with their annual frequencies nearly doubling in recent years.

Tropical Eastern Pacific Decadal Variability Drives Atlantic Multidecadal Variability: Two Distinct Pathways

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Using a tropical Pacific pacemaker experiment, we demonstrate that the tropical eastern Pacific (TEP) decadal sea surface temperature (SST) variability influences the Atlantic Multidecadal Variability (AMV) through two pathways. The TEP induces a North Atlantic SST tripole response that peaks 1 year later, primarily via modulation of net ...

Global‐Regional AI Weather Forecasting on a Stretched Cubed Sphere

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Regional weather hazards need local detail but remain constrained by the surrounding global circulation. Current AI weather forecasting mainly relies on globally uniform latitude‐longitude tensors, spherical graphs, or limited‐area models with external boundary forcing.

High‐ and Low‐Concentration Spiral Chlorophyll Bands Excited by Vortex Rossby Waves

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract High‐concentration spiral chlorophyll bands (HSCBs) embedded in oceanic mesoscale eddies have recently been observed worldwide. They are considered to be the footprints of vortex Rossby waves (VRWs). Based on satellite observations and drifter data, we identified additional low‐concentration spiral chlorophyll bands (LSCBs).
