Weak Positive Discharges Leading to Lightning Initiation

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Lightning‐initiating events in the Earth's atmosphere originate within compact regions of space with dimensions on the order of hundreds of meters. In the strongest events the associated current pulses propagate from positive to negative thundercloud charge centers at speeds approaching one tenth of the speed of light, a process referred to as

Repeatable Velocity Fine Structure of Lightning K‐Leaders From a Single VHF Interferometer Made Three‐Dimensional

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract K‐processes re‐illuminate lightning channels at speeds of order 107 m s−1, but measuring their three‐dimensional (3‐D) propagation velocity has required multi‐station systems available at few sites. An error‐isomorphism range inversion upgrades a single very‐high‐frequency interferometer (INTF) into a 3‐D imager: Lightning Mapping Array (LMA ...

Aqueous‐Phase Processing of Organic Aerosols at the Southern Great Plains: Insights From Integrated Chemical and Microphysical Analyses

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Aqueous‐phase reactions are hypothesized to be a major pathway for secondary organic aerosol (SOA) formation in humid, cloud‐influenced environments, yet direct observational constraints remain limited. Here we investigated aqueous SOA (aqSOA) formation and evolution during the spring 2016 Holistic Interactions of Shallow Clouds, Aerosols, and

Daily Peak Activity of the African Lightning Chimney Based on Meteosat Third Generation (MTG) Lightning Imager (LI), World Wide Lightning Location Network (WWLLN), and Schumann Resonance (SR) Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Lightning activity is strongly concentrated in tropical continental “chimneys”, among which the African lightning chimney stands out as the most intense globally. However, until recently, the incomplete and spatially uneven detection efficiency of ground‐based lightning networks, together with the limited spatio‐temporal coverage of satellite ...

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Microphysics and Kinematics of a High Flash Rate Storm With a Bottom‐Heavy Charge Structure

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract An atypical thunderstorm with unusual lightning and charge structure characteristics propagated through Cordoba province, Argentina, during the austral warm season in late 2018. This storm exhibited echo tops near 10.5 km, with high lightning activity concentrated at low altitudes.

Detection and Analysis of an Upward Jet‐Like Electrical Discharge Intercepting a High‐Altitude Research Aircraft

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract During a 2023 field campaign, a NASA ER‐2 research aircraft intercepted an upward jet‐like electrical discharge at 20 km altitude over an intense tropical thunderstorm. This event was analyzed using airborne multispectral optical sensors, electric field mills, X‐band radar, passive microwave, and ground‐based radio networks.

Dependence of Neutralized Charge Amount on Meteorological Conditions in Summertime Lightning Discharges in Japan

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Lightning discharges in Gunma Prefecture, Japan, from June–September 2023 were analyzed to explore the dependence of the neutralized charge amount on cloud structures embedded in weather systems, mainly based on in situ measurements of the ground‐based electric field, radar and satellite remote sensing, and numerical simulations using a bulk ...
