A New Global Climatological Model of the Equatorial Ionospheric Vertical E × B Drift: Integrating Ground‐Based Magnetometer, Radar, and Satellite Data Sets

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract We present a new empirical vertical E×B $\mathbf{E}\times \mathbf{B}$ drift model developed using ground‐based magnetometer, radar, and satellite data over equatorial latitude regions. We first implement an algorithm relating magnetometer derived equatorial electrojet (EEJ) and vertical ion plasma drift (equivalent to vertical E×B $\mathbf{E ...

Wavelet analysis of geomagnetically induced currents during the strong geomagnetic storms

Russian Journal of Earth Sciences, 2022
The main problem of electric utilities around the world is to ensure continuous power supply to consumers. One of the causes of power outages and blackouts can be geomagnetic storms during periods of the increased solar activity.

Topology Control Analysis Mitigations for Geomagnetically Induced Currents [PDF]

, 2016
Geomagnetic disturbances (GMD) are caused by corona mass ejections (CMEs) from the sun. These solar CMEs cause changes in the earths magnetic field, which in turn produce non-uniform electric fields.

Imprint of the Quasi‐Biennial Oscillation on the Ionosphere and Thermosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is a dominant mode of stratospheric variability and is known to modulate the variability of the ionosphere‐thermosphere (IT) system. However, the extent of its influence on the ionosphere‐thermosphere system remains uncertain due to weak signals and confounding with similar periodicities in solar flux.

The Contribution of Time Domain Structures to Electron Loss During the 17 March 2013 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Ring current modeling has been a subject of active research in the last two decades. However, accurately modeling of this population of particles remains a challenge. Several recent studies have demonstrated that ring current models can overestimate the trapped electron flux in the 10–50 keV range by up to two orders of magnitude during ...

Implementing Geomagnetically Induced Currents Mitigation During the May 2024 “Gannon” G5 Storm: Research Informed Response by the New Zealand Power Network

Space Weather
In early May 2024 ∼6 Coronal Mass Ejections were launched toward the Earth in short succession. This triggered the G5 “Gannon” geomagnetic storm lasting from ∼17 UT on 10 May 2024 to ∼9 UT on 12 May 2024.

Simulation of Geomagnetically Induced Currents in a Low‐Latitude 500 kV Power Network During a Solar Superstorm

Space Weather, 2022
Geomagnetically induced currents (GICs) are one of the main manifestations through which space weather affects human technical facilities, and GICs constitute the final link in the solar wind‐magnetosphere‐ionosphere‐ground interaction chain.

ULF Wave Modulation of Energetic Electron Precipitation Caused by the Self‐Limiting of Space Radiation: May 2024 Superstorm Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The May 2024 geomagnetic superstorm provided the opportunity to explore how strong wave‐particle interactions affect energetic electron precipitation under intense driving. Using coordinated measurements from a balloon‐borne Timepix‐based X‐ray detector, ground‐based riometers and magnetometers, and Arase satellite observations, we identified ...
