Risk assessment of power system oscillation instability based on geomagnetic storm events in the 24th solar cycle

IET Generation, Transmission & Distribution, 2022
When studying the harm of geomagnetic storms to the power system, the focus is often placed on the influence of transformers reactive power loss (GIC‐Q) caused by geomagnetic induced current (GIC) on voltage fluctuation.

Statistical nature of geomagnetic storms [PDF]

Journal of Geophysical Research: Space Physics, 1997
On the basis of geomagnetic activity indices and solar wind parameters, a superposed epoch analysis has been conducted for more than 300 geomagnetic storms. The intensity of magnetic storms is found to depend on the duration of the main phase; larger storms have longer timescales.

A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]

, 2010
Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

Magnetic field at geosynchronous orbit during high-speed stream-driven storms: Connections to the solar wind, the plasma sheet, and the outer electron radiation belt [PDF]

, 2010
Superposed-epoch analysis is performed on magnetic field measurements from five GOES spacecraft in geosynchronous orbit during 63 high-speed stream-driven storms in 1995–2005. The field strength and the field stretching angle are examined as functions of

Research on the effects and related mechanisms of geomagnetic storm on depression

Brain Research Bulletin
Objective: Depression has become disabling disease in the world. Geomagnetic storm is closely related to depression behavior, and melatonin is an important factor in the pathogenesis of depression. This study observed the effects of different intensities

Variation of Total Electron Content over Nepal during Geomagnetic Storms: GPS Observations

Russian Journal of Earth Sciences, 2023
Geomagnetic storms have very profound effects on the Total Electron Content (TEC) of the ionosphere. In order to investigate the equatorial and low-latitude ionospheric response to the geomagnetic storms of varying intensities, a detailed study of ...

Transequatorial magnetic flux loops on the sun: a possible new source of geomagnetic storms

Antarctic Record, 2009
Following the traditional way of expression, geomagnetic storms have been classified into three types; flare-type Sc storms, CH-type Sg storms, and DB-type Sc storms (Sc:sudden commencement;CH:coronal hole;g:gradual;DB:disparition brusque).We have ...

Relationship between geomagnetic storms and occurrence of ionospheric irregularities in the west sector of Africa during the peak of the 24th solar cycle

Frontiers in Astronomy and Space Sciences, 2022
The study of ionospheric irregularities is important since many technological systems might be influenced by the ionosphere. In this work, we use data from the Global Navigation Satellite Systems (GNSS) receiver installed in Abuja, Nigeria, GPS ...

Study of the Tidal Variations in the Ionosphere and the MLT Region over Mohe and Beijing During Six Intense Geomagnetic Storms from 2016 to 2021

Remote Sensing
Geomagnetic storms can cause large variations in the ionosphere, but their impacts on the mesosphere and lower thermosphere (MLT) are not well understood. Based on the Total Electron Content (TEC) data and the meteor neutral winds data over Mohe (53.5°N,
