Global Survey of Whistler Mode Waves in the Earth's Magnetosheath Using THEMIS Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract While it is known that whistler mode emissions are frequently detected in Earth's magnetosheath, their properties and dependence on solar wind conditions are not fully understood yet. In this study, we present the global distribution of whistler mode waves in the magnetosheath and their dependence on solar wind parameters, based on 7 years of ...

Rapid Recharge and Descent of Thundercloud Core Producing Gamma‐Ray Glow

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract We report two gamma‐ray glows observed on 22 December 2023, during a winter thunderstorm in Japan, using an array of four radiation detectors. The first glow, detected by one sensor, was quenched by a lightning discharge. The second glow appeared 2–3 min later and was tracked by three other detectors.

Contribution of Gravity Waves to the Lower Thermospheric Winter‐To‐Summer Meridional Circulation in High‐Resolution WACCM‐X

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract The mechanism driving the lower thermospheric meridional circulation is analyzed using the high‐resolution Whole Atmosphere Community Climate Model with thermosphere/ionosphere extension (WACCM‐X). In the winter lower thermosphere, eastward forcing is dominant around z=120 km, consistent with equatorward circulation. Following previous studies,
