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.

AMOC Weakening Controls δ18O but Not Rainfall in North China During Deglacial Abrupt Events

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract East Asian Summer Monsoon (EASM) varied at orbital and millennial timescales during the Last Deglaciation (∼20–11 ka). The uniform δ18O response in East China is often linked to EASM circulation that drives a precipitation dipole in North and South China on orbital scale.

Satellite Altimetry Reveals an Eddy Train Along the Ross Sea Shelf Break

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Oceanic circulation along the Antarctic shelf break regulates heat and material exchanges between the continental shelf and the open ocean, playing a crucial role in ice shelf melting and global overturning circulation. However, the circulation remains poorly understood due to limited observations.

Antarctic Sea‐Ice Extent Anomalies Impact Interannual Variability of Phytoplankton Chlorophyll‐a in Southern Ocean Frontal Zones

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The influence of sea‐ice variability on Southern Ocean phytoplankton productivity across frontal zones remains poorly quantified. Using 26 years (1998–2023) of satellite data, we quantified how sea‐ice extent anomalies (SIEA) impact surface phytoplankton Chlorophyll‐a (Chl‐a) anomalies across three frontal zones.

Historical and Projected Antarctic Sea Ice Trends Across High‐Resolution Coupled Model Hierarchies

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Coupled climate models generally simulate a decline in Antarctic sea ice extent (SIE) over the satellite period, failing to capture the observed near‐zero trend. Recent work has suggested that high‐resolution ocean models could ameliorate this issue via improved representation of mesoscale ocean processes, which may delay simulated Antarctic ...
