Direct Observational Evidence of the Mesoscale Gravity Wave Modulations on Low‐Latitude Sporadic E Layer

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Sporadic E (Es) layer plays essential role in ionosphere‐atmosphere coupling. Theoretical simulations show that the atmospheric gravity waves (GWs) in the lower thermosphere are the main modulatory source on Es dynamics at small spatial scales and short periods.

Limited Influence of Pre‐Existing Tropical Cyclones on Subsequent Cyclogenesis in the Western North Pacific

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract Previous studies suggest that a tropical cyclone (TC) may contribute to the genesis of another TC to its east or southeast in the western North Pacific (WNP) through Rossby wave dispersion. However, the influence of a pre‐existing TC (PTC) has not been fully clarified in realistic simulations.

The Characteristics of Pekeris Modes Revealed by Long‐Term Reanalysis Data JAWARA Covering the Entire Middle Atmosphere

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract The characteristics of Pekeris modes as well as Lamb modes are investigated using the new reanalysis data set JAWARA, which spans over 19 years and covers the entire middle atmosphere. Pekeris modes are a class of global normal modes whose energy is trapped in two height regions that is, around the stratopause and the surface, while the energy

Characterization of Crustal Deformation During the May 2021 Nyiragongo Eruption Using InSAR and GNSS Data

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract We analyze Interferometric Synthetic Aperture Radar (InSAR) and Global Navigation Satellite System (GNSS) data to characterize ground deformation and dike opening associated with the May 2021 Nyiragongo eruption. Despite documented eruptions in 1977 and 2002, Nyiragongo's magmatic system and its interaction with regional rifting remain poorly ...

Efficiency of Electromagnetic Energy Transfer From Solar Wind to Ionosphere Through Magnetospheric Ultra‐Low Frequency Waves

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ultra‐low frequency (ULF) waves are a ubiquitous carrier of energy in geospace. However, their efficiency in transferring solar wind energy into the upper atmosphere remains a fundamental and not well‐understood question. This is due to their global presence, which cannot be fully quantified by spatially limited observations, and the need for ...
