Analysis of the Charge Structure and Lightning Activity During a Severe Beijing Thunderstorm via an Innovative Balloon‐Borne 3D Electric Field Observation System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,

Evaluation of a Decade of Methane Observations From a Tower Network in Indianapolis, Indiana

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Methane (CH4) is a critical near‐term climate mitigation target, yet urban sources remain poorly constrained. Indianapolis hosts one of the world's longest and densest urban CH4 data sets, with continuous measurements from a tall‐tower network spanning more than a decade.

Observations of Offshore Low‐Level Jets Off the U.S. East Coast Reveal Systematic Biases in ERA5 and HRRR

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Low‐level jets (LLJs)—wind speed maxima typically occurring a few hundred meters above the surface—are common off the U.S. East Coast and influence many atmospheric processes with societal importance, including cloud formation, aviation safety, and search‐and‐rescue.

Evaluation of AMSU‐A and MHS Radiance Assimilation Strategies in MPAS–JEDI 4DEnVar for Mountain‐to‐Plain Convection Over Beijing, China

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract To improve numerical prediction of mountain‐to‐plain (MTP) convection over the Beijing region, this study uses the MPAS–JEDI four‐dimensional ensemble‐variational (4DEnVar) data assimilation system on a global 3–60 km variable‐resolution mesh to evaluate assimilation strategies for radiances from the Advanced Microwave Sounding Unit‐A (AMSU‐A)

An observational study of lee waves using radiosonde data [PDF]

Tellus A: Dynamic Meteorology and Oceanography, 1972
Corby (1957) showed that radiosonde data could be used to detect departures of the ver- tical velocity of the instrument, of a few m sec-l, from a mean value. Occasionally marked periodic variations of the vertical velocity along the path of the balloon suggested the presence of atmospheric gravity waves, almost certainly due to orography, extending ...

Evaporation and Cold Pools Beneath Trade Cumulus Clouds

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The sources of air and water vapor in the tropical trade‐wind Atlantic subcloud boundary layer (SBL) are analyzed using in situ measurements of temperature, specific humidity, and stable water isotopologues (HDO and H218O) from shipboard observations in January‐February 2020.

Understanding the Response of the Quasi‐Biennial Oscillation to Carbon Dioxide and Sea Surface Temperature Increases in Aqua‐Planet Simulations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) of the tropical stratospheric zonal winds influences tracer transport, the stratospheric polar vortex, and extra‐tropical surface variability. However, the response of the QBO to increasing greenhouse gas concentrations is still uncertain.

3D Water Vapor Signature of Tropical Storms: GNSS Tomography of the 10 Most Severe Rainfall Events in Hong Kong 2015–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Monitoring water vapor during extreme events is crucial for understanding atmospheric physics, as well as for improving the prediction of severe weather and enhancing early warning systems. The major gap in monitoring water vapor during extreme events lies in the limited spatial and temporal resolutions of existing techniques.

High‐Resolution Modeling to Quantify CO2 Emissions From an Industrial Point Source

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Orbiting Carbon Observatory‐3 (OCO‐3) provides precise observations of the column‐averaged dry air mole fraction of carbon dioxide (XCO2 ${\text{XCO}}_{2}$) with the ability to target specific areas using the Snapshot Area Maps (SAMs).
