Climatological Statistics of Extreme Geomagnetic Fluctuations With Periods From 1 s to 60 min
Space Weather, 2021 Using a global database of 125 magnetometers covering several decades, we present occurrence statistics for fluctuations of the horizontal geomagnetic field (dBh/dt) exceeding the 99.97th percentile (P99.97) for both ramp changes (Rn) and the root‐mean ...

Localized Threats: How Ground Conductivity Shapes the Geoelectric Response
Space Weather, Volume 24, Issue 3, March 2026.Abstract Geomagnetic storms can induce strong geoelectric fields in the ground. These fields drive geomagnetically induced currents in technological conductor systems, such as power grids. In this study, we analyze 4‐hr periods of two such major geomagnetic storms: the Halloween storm (29–31 October 2003) and the 7–8 September 2017 storm.

Journal of Space Weather and Space Climate, 2015 Previous studies have demonstrated a close relationship between the time derivative of the horizontal geomagnetic field vector (dH/dt) and geomagnetically induced currents (GIC) at a nearby location in a power grid.

Geomagnetic Pulsations Driving Geomagnetically Induced Currents
Space Weather, 2021 Geomagnetically induced currents (GICs) are driven by the geoelectric field induced by fluctuations of Earth's magnetic field. Drivers of intense GICs are often associated with large impulsive events such as coronal mass ejections.

Modelling the effects of space weather at the Earth’s surface : a UK geoelectric field model [PDF]
, 2004 Geomagnetically Induced Currents (GIC), which can flow in technological systems such as power transmission grids, are a consequence of the geoelectric field induced at the surface of the Earth during geomagnetic storms.

Space Weather, Volume 24, Issue 3, March 2026.Abstract It is important to be able to accurately predict geoelectric field behavior so that potential space weather hazards to large grounded infrastructure, such as electric power grids, smart grids, oil and gas pipelines, and railway systems, can be better understood.

Influence of Tectonic and Geological Structure on GIC in Southern South Island, New Zealand
Space Weather, 2023 As part of a 5‐year project to assess the risk posed by geomagnetically induced currents (GIC) to the New Zealand electrical transmission network, long‐period magnetotelluric (MT) measurements have been made at 62 sites in southern South Island of New ...
