Quantifying Nighttime Gravity Wave‐Driven Mesosphere‐Ionosphere Coupling Over CONUS Using NASA AWE Radiance and GNSS TEC Observations

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We present the first coordinated study of nighttime mesosphere‐ionosphere coupling over the continental United States (CONUS) from January through November 2024 using NASA Atmospheric Waves Experiment (AWE) airglow measurements near 87 km and GNSS Total Electron Content observations near 300 km.

Assessment of climatic extremes over Northeast and West Coast regions of India

Geoadria, 2015
Extreme weather and climate variability have become a subject of big concern worldwide. In response, efforts have been made to evaluate the trends in climatic parameters in two geographical regions of India – Northeast (NER) and West coast region (WCR ...

Gamma‐Ray Glows Commonly Followed by Lightning: A Statistical Study of the Spatio‐Temporal Relationship

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Gamma‐ray glows are prolonged enhancements of gamma rays from thunderclouds, which are often linked to large‐scale electric fields rather than individual lightning. The link between glows and lightning remains poorly understood. Here, we analyzed 300 glows observed during the ALOFT aircraft campaign and optical lightning detected by GLM.

Potential Benefits of Assimilating Phased Array Radar Data for Convective‐Scale Analysis and Prediction of Supercell Storms: A Proof‐of‐Concept OSSE Study

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract This study investigates the impact of phased array radar (PAR) scanning strategies on short‐term convective‐scale analyses and forecasts through an Observing System Simulation Experiment framework. The Weather Research and Forecasting model, coupled with the Data Assimilation Research Testbed ensemble adjustment Kalman filter, is used to ...

Distinct Characteristics of Convectively Induced Turbulence (CIT) and Non‐CIT in the Western Pacific Using In Situ Aircraft Data and GK‐2A Satellite Data

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract This study introduces a newly defined turbulence patch that includes continuous turbulence reports of in situ aircraft data, separating at least 5‐min from others. This enables the individual turbulence patch to be characterized more easily by their possible sources than by an isolated data point.

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 ...
