Long‐Lived Equatorial Plasma Bubbles Persisting Into the Afternoon Over the Pacific Sector During the Recovery Phase of the April 2023 Geomagnetic Storm

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Equatorial plasma bubbles (EPBs) are typically nighttime ionospheric irregularities, and their persistence into daytime sectors remains insufficiently understood. Here, we investigate long‐lived EPB‐related plasma depletion structures over the Pacific sector during the recovery phase of the 23–25 April 2023 geomagnetic storm using Formosa ...

Traveling ionospheric disturbances propagating ahead of the Tohoku-Oki tsunami: a case study,

, 2016
International audienceWe document two kinds of traveling ionospheric disturbances, namely, CTIDs (Co-tsunami-Traveling-Ionospheric-disturbances) and ATIDs (Ahead-of-Tsunami-Traveling-Ionospheric-disturbances) related to the Tohoku-Oki tsunami of 2011 ...

The Turkey Earthquake Induced Equatorial Ionospheric Current Disturbances on 6 February 2023

Remote Sensing
An earthquake is a seismic event resulting from a sudden release of energy in the lithosphere, which produces waves that can propagate through the atmosphere into the ionosphere, causing ionospheric disturbances, and excites an additional electric field ...

Revisiting the Ionospheric Disturbances Over Low Latitude Region of China During Super Typhoon Hato

Space Weather
The ionosphere exhibits complex variations due to the influences from above and below. To distinguish the source of ionospheric disturbances is important for understanding the variation process and the coupling mechanism among different regions.

Uplift of the ionosphere by tropospheric and thermospheric Lamb waves induced by the 2022 Tonga volcanic eruption

Geoscience Letters
On 15 January 2022, the Tonga submarine volcano eruption generated atmospheric shocks, air pressure perturbations, tsunamis, etc., inducing traveling atmospheric disturbances (TADs) and traveling ionospheric disturbances (TIDs).

Ionospheric disturbances in Japan detected by ALOS-2 subband azimuth offset

Earth, Planets and Space
Global Navigation Satellite Systems (GNSS) and synthetic aperture radar (SAR) are valuable tools for observing ionospheric disturbances. While GNSS provides continuous temporal data with limited spatial resolution, SAR offers high-resolution spatial ...

Multi‐Step Gravity Wave Propagation From a Tropospheric Vortex to the Ionosphere Near the Tibetan Plateau

Geophysical Research Letters
The atmosphere and ionosphere form a vertically coupled system in which disturbances in the lower atmosphere can modulate ionospheric variability. Using reanalysis data, ground‐based GNSS observations, and COSMIC‐2 profiles, we investigate gravity waves (
