Chorus Element Repetition: Roles of Energetic Electron Injection and Nonlinear Wave Growth

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Chorus waves are coherent whistler‐mode emissions in Earth’s magnetosphere and play a key role in the acceleration and loss of radiation belt electrons. Their spectra commonly consist of discrete and repetitive elements, yet the mechanism governing this repetition is not fully understood.

Modeling Storm‐Time Post‐Midnight Equatorial Plasma Bubbles With SAMI3‐WACCMX: Impacts of Neutral Winds, Thermospheric Composition, and Atmospheric Waves

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract This study investigates the roles of neutral winds, composition and atmospheric waves in storm‐time post‐midnight equatorial plasma bubble (EPB) development using the coupled SAMI3‐WACCMX model. Simulations reveal the formation of post‐midnight EPBs extending beyond 1,500 km in altitude and persisting into the post‐sunrise period.

Near‐Field Acoustic and Gravity Wave Modes in the Ionosphere Triggered by Ground Motion and Tsunami During the 2024 Mw7.4 Hualien Earthquake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The interaction between the atmosphere and other components of the Earth system, such as the solid Earth and the oceans, remains an open and active area of research. In particular, the dynamic response of the ionosphere to forcing from below, such as earthquakes and tsunamis, is not yet fully understood.

Substorm Effects on Chorus Emissions Modulated by ULF Waves

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.

Geomagnetic Field Influence on Trans‐Ionospheric HF Wave Propagation via Topside Z–to–O Mode Conversion

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Satellite observations during ionospheric modification experiments have reported trans‐ionospheric high‐frequency (HF) wave propagation even when the pump frequency lies below the peak plasma frequency. Such behavior is often attributed to large‐scale density irregularities that locally permit ordinary‐mode (O‐mode) propagation, but this does ...
