An Assessment of Representing Land‐Ocean Heterogeneity via CAPE Relaxation Timescale in the Community Atmospheric Model 6 (CAM6)

Journal of Advances in Modeling Earth Systems
The time needed by deep convection to bring the atmosphere back to equilibrium is called convective adjustment timescale or simply adjustment timescale, typically denoted by τ. In the Community Atmospheric Model|Community Atmosphere Model (CAM), τ is the

Boundary‐Aware Physical Constraints Refine Satellite Precipitation Occurrence Over the Qinghai‐Tibet Plateau

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Over complex terrain, hourly precipitation occurrence estimates are often distorted by weak, persistent, and mistimed wet hours that are poorly constrained by independent time‐step classification. Using 1,232 hourly gauge records over the Qinghai‐Tibet Plateau (QTP), we develop a boundary‐aware physical‐constraint framework that learns ...

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 ...

Gravity Wave Energy Baselines (∼30–110 km) Established From Lidar Observations at McMurdo (77.84°S, 166.67°E), Antarctica: Energy Dissipation and Constituent Diffusion

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Lidar observations above McMurdo, Antarctica from 2011 to 2024 are used to characterize gravity wave (GWs) potential energies (Ep ${E}_{p}$) in the mesosphere and lower thermosphere (MLT). Alongside characterizations in the middle atmosphere (30–70 km), the GW baselines show dissipation at all altitudes from 30 to 110 km.

Unifying Observations, Simulations, and Theory for Drizzle Size Distribution Tails

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The onset and rate of drizzle remain open problems in atmospheric physics. This study brings together theory, simulations, and observations to analyze the emergence of power‐law tails in droplet size distributions as a signature of a dynamic steady state with coalescence growth balanced by sedimentation removal.

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 ...

Regional and Seasonal Variability in Decreasing Contrail Cirrus Cloudiness Using Sustainable Aviation Fuel

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract The impact of aviation induced contrail cirrus on Earth's radiation budget depends on the optical depth (OD) and the life time of these clouds. Their tendency to enhance global warming may be mitigated by replacing conventional kerosene with fuels that form fewer soot particles, such as sustainable aviation fuels (SAF). The resulting reduction

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.
