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.

Improved Representation of Surface Emissivity Effects on Longwave Radiation in a Coupled Earth System Model

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Many Earth System Models (ESMs) approximate surface emissivity as constant over all wavelengths (broadband). This approximation misrepresents the spectral distribution of longwave (LW) flux and introduces error in the LW atmospheric heating rate.

Model Sensitivities of Biomass‐Burning Aerosol Chemical Aging, Sulfate Formation, and Cloud Droplet Activation in the Southeastern Atlantic Using CESM and E3SM

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Biomass‐burning smoke drives large uncertainty in climate projections of the Earth's radiative balance. This is due to the chemical and physical evolution of smoke and its impact on clouds and radiation. Here we focus on the southeastern Atlantic region and its inflow of African biomass‐burning smoke during August 2017.

The Impact of Volatile Organic Compounds and Oxides of Nitrogen on Ground‐Level Ozone and Secondary Organic Aerosols Formation Over the Triad Region in North Carolina

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Ground‐level ozone and secondary organic aerosol (SOA) formation in urban‐rural environments involves complex interactions between nitrogen oxides (NOx) and volatile organic compounds (VOCs). This study employed WRF‐Chem version 4.2 with SAPRC99 chemistry to investigate ozone and SOA formation in the Triad region NC during peak photochemical ...

Uncertainty‐Aware Machine Learning for Onset of Deep Convection: Under what Conditions Are Trigger Predictions More Reliable?

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Machine Learning (ML) models have emerged as a powerful tool for predicting deep convection triggering, yet the atmospheric conditions that systematically challenge these models in detecting deep convection remain poorly understood. To diagnose such ambiguous regimes, we trained a Controlled Abstention Neural Network (CAN) that separates high‐

Improvement of Stable Atmospheric Boundary Simulation with High-Spatiotemporal-Resolution Nudging over the North China Plain

Atmosphere
The WRF model often struggles to accurately replicate specific characteristics of the atmospheric boundary layer, particularly under highly stable conditions.

Diurnal Pulses in Tropical Cyclones as Convectively Coupled Gravity Waves

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract This study uses convection‐permitting simulations to examine the vertical extent, propagation, and nighttime preference of diurnal pulses (DPs) in tropical cyclones (TCs). DPs are outward‐moving rings of cooler brightness temperatures near the storm center and may indicate TC intensification.

Effect of Optical Illumination on Bubble Nanodomains

Advanced Functional Materials, Volume 36, Issue 65, 13 August 2026.
Stable surface‐confined nanoscale bubble domains are created and manipulated in PMN‐PT single crystals. Under above‐bandgap illumination, these bubble nanodomains remain unchanged. However, upon illumination cessation, they rapidly expand to switch the entire crystal surface, due to the accumulation of a large reservoir of electrons at the crystal ...

Damaging Surface Hail in Simulations of Satellite‐Detected Hailstorms in Australia's Tropics

Atmospheric Science Letters, Volume 27, Issue 8, August 2026.
Satellite detections of hail signatures are uncertain in the tropics, where the deep troposphere increases the chances that ice detected aloft will melt before it reaches the surface. We used numerical weather simulations to examine the plausibility of damaging surface hail at times and locations when satellites detected hail signatures over Australia ...
