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.

Global Flash Drought Prediction Through Evaporative Stress Forecasting

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Flash droughts pose severe risks to societies and ecosystems due to their sudden onset and rapid intensification. Predicting their vegetation impacts at subseasonal timescales remains difficult. Advances in hybrid physics‐AI models and weather forecasting create new opportunities to enhance the predictability of evaporative stress, a key ...

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 ...

Intercomparison of mesoscale meteorological models

, 2004
In the framework of the RAPHAEL EU project, a series of past heavy precipitation events has been simulated with different meteorological models. Rainfall hindcasts and forecasts have been produced by four models in use at various meteorological services or research centres of Italy, Canada, France and Switzerland. The paper is focused on the comparison

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).

The Role of Lightning in Atmospheric Chemistry

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

Convection‐Permitting Projections of Low‐Level Jets and Mesoscale Convective Systems in South America

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Anthropogenic warming is expected to substantially modify the hydroclimate of South America, a region in which low‐level jets (LLJs) and mesoscale convective systems (MCSs) are key components of moisture transport and precipitation. However, the responses of these systems to future climate change, including the relative roles of thermodynamic ...

Atmospheric River‐Cyclone Events Disrupting an Antarctic Peninsula Field Campaign: Dynamics, Mesoscale Wind Amplification, and Long‐Term Context

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Extreme weather in the Antarctic Peninsula arises from interactions among large‐scale circulation variability, atmospheric rivers (ARs), extratropical cyclones, and complex coastal terrain, yet the linkages across these scales remain insufficiently resolved.

An Integrated Process‐Based Approach for Interpreting Precipitation Isotopes Using North‐Central Texas as a Testbed

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract The isotopic composition of precipitation reflects the combined influences of moisture sources, rainout history, and convective intensity, but the relative importance of these controls varies among regions and remains poorly understood in continental settings.

Gray‐Zone Simulation of the Dry Convective Boundary Layer Using Fourier Neural Operator

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Previous machine learning (ML) weather prediction models primarily focus on global mesoscale forecasting. This study develops three‐dimensional Fourier neural operator (FNO) models for simulating the dry convective boundary layer (CBL) at 800‐m grid spacing, which is a resolution in the gray zone. The filtered large‐eddy simulation data of the
