Satellite‐Derived Leaf Photosynthetic Capacity Data Set Improves Atmospheric Inversion of Terrestrial Carbon Fluxes

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Accurately estimating the terrestrial carbon sink is crucial for understanding the global carbon cycle. Here, we examine how different parameterizations of the key leaf photosynthetic capacity parameter, namely the maximum Rubisco carboxylation rate normalized to 25°C (Vcmax25), influence terrestrial carbon flux estimates within an atmospheric

Assessing the Impact of Countergradient Fluxes on the General Circulation in the Community Atmosphere Model

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Parameterizing boundary layer turbulence in Earth System Models (ESMs) introduces a key source of uncertainty. Here, we explore the impact of implementing a prognostic formulation (PMF) for momentum flux, which permits countergradient (CG) fluxes.

Drying Effect of Landfalling Tropical Cyclones

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The high precipitation efficiency of tropical cyclones (TCs) is theorized to dehydrate the atmosphere, a process with important climate implications that has yet to be confirmed by direct observational evidence. Using satellite and reanalysis data, this study statistically examines the drying effect of landfalling TCs. Results indicate a local

Surface Anthropogenic NOx Emissions Drive 1995–2014 Increase in Tropospheric Ozone: Implications for Ozone and Methane Radiative Forcing

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Tropospheric ozone influences Earth's radiative energy budget and has increased in recent decades. With initial‐condition ensembles from a single chemistry‐climate model, we show that global surface anthropogenic NOx emissions explain about 90% of the simulated 1995–2014 tropospheric ozone increase (1.8 DU) and that this increase exceeds those

Tracing Hailstone Development: Isotopic Evidence and Microphysical Variability in Texas Supercell Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Two supercell thunderstorms that occurred in Del Rio and Burkburnett, Texas in the spring of 2020 produced greater than 5 cm diameter hailstones. Fourteen hailstones, eight from Del Rio and six from Burkburnett, were cut in half along the maximum principal axis. Half the hailstone was dissected at 0.5 cm increments, providing 198 subsamples of

Understanding Drought‐Induced Soil Moisture Feedback on Atmospheric Circulation: Observations and Simulation Experiments of the 2020 Western U.S. Drought

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract This study examines the large‐scale atmospheric response to reduced evapotranspiration during droughts in the Western U.S., using an observation‐based regression method and numerical experiments with a global climate model. We found that Western U.S.

Statistical Characteristics of Environments of Precipitating Mesoscale Convective Systems During the Pre‐Summer Season Over South China

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Mesoscale convective systems (MCSs) are known to induce heavy rainfall and pose significant weather hazards in tropical and mid‐latitude regions. Understanding the environmental conditions of MCSs is essential for improving model simulations and operational precipitation forecasts.

Dynamic Versus Diabatic Controls on Atmospheric Variability in a Tropical Aquachannel

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Synoptic‐ to planetary‐scale atmospheric variability in the tropics is a potential source of predictability worldwide. However, current weather prediction models struggle to fully capture this variability. Here, we conduct tropical aquachannel simulations using the ICOsahedral Nonhydrostatic model with horizontal grid spacings of 13 and 5 km ...

Linkage Between Atmospheric Rivers and Overshooting Convection and Their Roles on UTLS Water Vapor During the North American Monsoon: Insight From DCOTSS

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Overshooting convection significantly impacts the composition of the upper troposphere and lower stratosphere (UTLS), yet its linkage to Atmospheric Rivers (ARs) remains poorly understood. This study investigates how ARs modulate environmental conditions and moisture distribution associated with overshooting convection in the central and ...

Impact of Doubled CO2 on the Response of the Mesosphere, Thermosphere, and Ionosphere to the 2008–2009 Sudden Stratospheric Warming

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We investigate the impact of the 2008–2009 sudden stratospheric warming (SSW) event on the mesosphere, thermosphere, and ionosphere under conditions of doubled carbon dioxide (CO2). Using the Specified Dynamics Whole Atmosphere Community Climate Model with thermosphere‐ionosphere eXtension model, we perform two simulations for the 2008–2009 ...
