Inverted Charge Structure in a Tibetan Plateau Thunderstorm

Geophysical Research Letters
The inverted tripole charge structure in thunderstorm over the central Tibetan Plateau was discovered for the first time, primarily through observations from lightning very high frequency interferometer capable of high‐precision lightning channel mapping.

Assessing different implementation modalities of an EdTech intervention for lower‐primary learners: A difference‐in‐difference study in Sierra Leone

British Journal of Educational Technology, Volume 57, Issue 3, Page 775-796, May 2026.
Abstract This paper presents findings from a quasi‐experimental difference‐in‐difference study on three different implementation modalities of the same EdTech intervention, implemented in Pujehun district in Sierra Leone. It offers a critical discussion of the impact of two different personalised modalities and one non‐personalised modality on literacy

Thunderstorm vertical velocities and mass flux estimated from satellite data [PDF]

Infrared geosynchronous satellite data with an interval of five minutes between images are used to estimate thunderstorm top ascent rates on two case study days. A mean vertical velocity of 3.5/ms for 19 clouds is calculated at a height of 8.7 km.

Effects of low‐tech, process‐based restoration on riparian plant communities and soil moisture of streams in the Northern Great Plains (NGP) of the United States

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Process‐based restoration is novel in livestock production systems of the Northern Great Plains (NGP), and limited region‐specific evidence can impede adoption. We investigated the effects of methods such as beaver dam analogs (BDAs) on NGP plant communities.

Atmospheric Rivers Are a Frequent Source of Moisture Transport in Severe Convective Storm Environments

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Atmospheric rivers (ARs) are well known for their contributions to precipitation and flooding across the U.S. The present study explores the relationship between ARs and the potential for severe thunderstorms and tornadoes over the U.S. in both the warm and cool seasons during a 20‐year period from 2004 to 2023.

Detecting Thunderstorm‐Related High‐Energy Phenomena in Weak Signals

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Gamma‐ray glows (GRGs) are high‐energy events associated with thunderstorms, characterized by an enhancement of the high‐energy background radiation lasting from a few seconds to several minutes. They are typically detected near their sources by balloons, aircraft, mountain‐based observatories, or at sea level in regions where thunderstorms ...

Initiation of non-tropical thunderstorms by solar activity [PDF]

Correlative evidence accumulating since 1926 suggests that there must be some physical coupling mechanism between solar activity and thunderstorm occurrence in middle to high latitudes.
