Analyses of Atmospheric Turbulence Near Surface Observed by Uncrewed Aerial Vehicle in the Suburban Area of Seoul Metropolitan, South Korea

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract As the use of uncrewed aerial vehicles (UAVs), ranging from small drones to large person‐transport vehicles, continues to expand, detailed wind and turbulence observations near surface in urban areas are crucial for safe flight planning. In summer 2021, a field campaign was conducted in the suburbs of Seoul, South Korea, using a UAV equipped ...

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,

Postfrontal Deep Convection Over the Southern Ocean and Orographic Precipitation Enhancement Over Tasmania

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The orographic precipitation enhancement (OPE) generated within wintertime post‐frontal air masses is a prominent climate feature of Tasmania. This study investigates a passage of a cold sector of a mid‐latitude cyclone over the Southern Ocean (SO) and Western Tasmania (WTAS) observed from 2100 UTC 11 July to 0300 UTC 13 July.

To Align or Not to Align? That Is the Question

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Previous studies have shown that vertically misaligned circulations are commonly found in weaker tropical cyclones (TCs) below hurricane strength, whereas TCs of hurricane intensity more typically exhibit vertically aligned vortices. Thus an important step in the TC intensification process is achieving a vertically aligned circulation.

Linking Interregional NASA Airborne Observations of Near‐Storm Environments to Tropical Oceanic Convective Structure

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Deep tropical oceanic convection is a key component of the tropical atmosphere, with environmental moisture and vertical wind shear influencing its structure and intensity. However, attempts to generalize convection‐environment relationships across the broad‐scale tropics have produced inconsistent results, partly owing to limits of reanalysis,
