Transport to the Extratropical Stratosphere by Overshooting Storms in Idealized Simulations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Deep convection is a significant source of water to the extratropical stratosphere which can alter radiative properties and contribute to ozone loss. Previous studies find it responsible for 40% of mid‐latitude water vapor above 380K. However, the amount of hydration from individual storms and the mechanisms that initiate mixing is less ...

TGFs, Gamma‐Ray Glows, and Direct Lightning Strike Radiation Observed During a Single Flight of a Balloon‐Borne Gamma‐Ray Spectrometer

Earth and Space Science
Terrestrial gamma‐ray flashes (TGFs) and other high‐energy radiation phenomena related to thunderstorms remain incompletely understood since their discovery nearly 30 years ago.

A Two‐Dimensional Deep Learning Scheme With One Predicator Only to Parametrize Global Lightning

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Lightning simulation has long posed significant challenges. This study presents a novel two‐dimensional artificial intelligence‐based global lightning scheme that uses a single predictor, convective available potential energy (CAPE). The new scheme significantly improves global lightning simulation performance, achieving a determination ...

Solar modulation of atmospheric electrification through variation of the conductivity over thunderstorms [PDF]

It is suggested that variations of the current in the global atmospheric electrical circuit can be produced through regulation of the resistance between the tops of thunderclouds and the ionosphere.

Roles of Surface Latent Heat Flux and Gravity Waves in Offshore MCS Development in the Coastal Eastern Tropical Pacific

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The eastern tropical Pacific (ETP) coastal region, one of the rainiest places on Earth, is characterized by distinct diurnal offshore rainfall propagation primarily driven by mesoscale convective systems (MCSs). Previous studies have shown that MCS initiation in this region peaks in the early morning, with diurnally generated gravity waves ...

Urban Land Surface Effects on Summertime Clouds and Moist Convection in Houston Under Different Synoptic Conditions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Urban landscapes modify cloud formation and convection through complex thermodynamic and aerodynamic processes; however, their influence under different synoptic regimes remains poorly understood. This study investigates the impact of the Houston metropolitan area on summertime cloud cover and convective cell characteristics using a ...

Future Climate Projections of Hazardous Convective Weather Using an Ensemble of Environment‐Informed, Convection‐Permitting Dynamical Downscaling Simulations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Convection‐permitting dynamical downscaling (CPDD) allows for an explicit representation of the convective storms that generate tornadoes, hail, severe thunderstorm winds, and locally heavy precipitation. Possible changes in such hazardous convective weather (HCW) due to human‐induced climate change are therefore projected with higher ...

South American Mesoscale Convective Systems: Present and Future Climates

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract This study investigates the mesoscale convective systems (MCSs) over South America in a future climate using two distinct modeling approaches: the Weather Research and Forecasting (WRF) regional model with dynamical downscaling and pseudoglobal warming, and the Nonhydrostatic Icosahedral Atmospheric Model (NICAM) global cloud‐resolving model ...
