Rapid Changes in Southern Ocean Upper‐Water Temperature Linked to Shift of the Southern Hemisphere Westerlies Since the Last Glacial

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The pattern and cause of upper‐water temperature (UWT) variations on millennial timescales in the Southern Ocean (SO) and the mechanism of their interaction with high‐latitude Northern Hemisphere climate remain unclear. Here, we reconstructed millennial‐scale subsurface temperature (subST) records from the Weddell Sea during the Last Glacial ...

Exploring Antarctic Feedback Mechanisms Using Two‐Way Coupled Subglacial Hydrology and Ice Flow Modeling in the Siple Coast

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The Siple Coast region of West Antarctica is known for its fast flowing, topographically unconstrained ice streams that evolve due to subglacial conditions. In this work, we analyze the nature of the Siple Coast subglacial hydrologic system and its interactions with the ice sheet using two‐way coupled subglacial hydrology and ice flow modeling.

Toward an Advanced Benchmark for Aerosol Radiative Forcing: A Chemically Resolved Sectional Aerosol Scheme in E3SMv3

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Aerosol radiative effects are the largest uncertainty in anthropogenic forcing estimates due to challenges in accurately representing aerosol properties and aerosol‐cloud interactions. In this study, we implement the Advanced Particle Microphysics module (APM) into the Energy Exascale Earth System Model (E3SMv3) to represent evolving size ...

A New Lidar‐Based Observational Estimate for a Short‐Term Longwave High‐Cloud Feedback

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract High clouds play a substantial role in modulating the Earth's top‐of‐atmosphere radiative energy budget. Models project that changes in high‐cloud altitude and area in response to warming will have a net warming effect within the tropics. Yet, to our knowledge, a robust global observational constraint of a short‐term cloud feedback associated ...

Evaluation of Low‐Level Clouds, Temperature, and Surface Radiation Using a Model, Two Reanalyses, and Southern Ocean Observations

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Low‐level clouds over the Southern Ocean (SO) exert a strong influence on surface radiation, yet their representation in reanalyses and climate models remains uncertain. We evaluated cloud properties and surface radiative fluxes from ERA5, MERRA‐2, and the CAM‐ATRAS model using observations obtained over the SO by Japan's R/V Shirase during ...
