Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Atmospheric gravity waves (GWs) are believed to transport energy and momentum between different regions of the atmosphere. Historically, observations of these waves from both ground and space have been relatively abundant at altitudes up to the lower thermosphere, and somewhat less abundant in the upper thermosphere and F‐region ionosphere ...

Evolution of Ionospheric Ion Upflow Flux During the April 2023 Geomagnetic Storm
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract We study the impact of the evolving magnetosphere‐ionosphere‐thermosphere system on upward ion fluxes during the 23–24 April 2023 geomagnetic storm. This storm has a “double‐dip” structure where two southward IMF Bz ${\mathrm{B}}_{z}$ periods cause two dips in the SYM‐H index.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) have long been a subject of interest in ionospheric research. However, their spatiotemporal variability across regions, local times, seasons, and solar cycles is very complicated and remains not well established.
