Ionosphere over Eastern North Atlantic Midlatitudinal Zone during Geomagnetic Storms

open access: yesAtmosphere, 2023
The ionospheric response at middle latitudes to geomagnetic storms is not yet very well understood. Total electron content (TEC) variations associated with eight strong geomagnetic storms between 2015 and 2022 obtained from GNSS receivers in the eastern ...

Ionospheric redistribution during geomagnetic storms [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2013
The abundance of plasma in the daytime ionosphere is often seen to grow greatly during geomagnetic storms. Recent reports suggest that the magnitude of the plasma density enhancement depends on the UT of storm onset. This possibility is investigated over a 7year period using global maps of ionospheric total electron content (TEC ...

A Statistical Study of the Correlation between Geomagnetic Storms and M ≥ 7.0 Global Earthquakes during 1957–2020 [PDF]

open access: yesEntropy, 2020
In order to find out whether the geomagnetic storms and large-mega earthquakes are correlated or not, statistical studies based on Superposed Epoch Analysis (SEA), significance analysis, and Z test have been applied to the Dst index data and M ≥ 7.0 ...

On extreme geomagnetic storms [PDF]

open access: yesJournal of Space Weather and Space Climate, 2014
Extreme geomagnetic storms are considered as one of the major natural hazards for technology-dependent society. Geomagnetic field disturbances can disrupt the operation of critical infrastructures relying on space-based assets, and can also result in terrestrial effects, such as the Quebec electrical disruption in 1989. Forecasting potential hazards is

Mid-latitude ionosphere during two great geomagnetic storms

open access: yesAnnals of Geophysics, 1996
The ionospheric disturbances observed at many European ionosonde stations in association with the severe geomagnetic storms occurring on 19-20 December 1980 and 11-12 April 1981 were investigated by using the available ionospheric and geomagnetic data ...

Plasmaspheric dynamics resulting from the hallowe'en 2003 geomagnetic storms [PDF]

open access: yes, 2009
Cross-phase-derived plasma mass density trends during the Hallowe'en 2003 geomagnetic storms are presented for 38° magnetic latitude 63° (1.61 ≤ L ≤ 5.10), using data from the SAMNET (Subauroral Magnetometer Network), BGS (British Geological Survey), and

Particle precipitation during ICME-driven and CIR-driven geomagnetic storms [PDF]

open access: yes, 2008
Interplanetary coronal mass ejections (ICME) and corotating interaction regions (CIR) alter the parameters of the solar wind and interplanetary magnetic field (IMF) that affect conditions in the Earth's magnetosphere and particle precipitation in the ...

Statistical study and corresponding evolution of plasmaspheric plumes under different levels of geomagnetic storms [PDF]

open access: yesAnnales Geophysicae, 2022
Using observations of Van Allen Probes, we present a statistical study of plasmaspheric plumes in the inner magnetosphere. Plasmaspheric plumes tend to occur during the recovery phase of geomagnetic storms.

DAYTIME ELECTRON DENSITY AT IONOSPHERIC F1-LAYER HEIGHTS DURING GEOMAGNETIC STORMS (IRKUTSK)

open access: yesSolar-Terrestrial Physics, 2022
We have examined variations in electron density Ne at ionospheric F1-layer heights during geomagnetic storms at the Irkutsk ionospheric station (52° N, 104° E). We have selected geomagnetic storms of varying intensity as well as quiet days for each event

Differences between CME-driven storms and CIR-driven storms [PDF]

open access: yes, 2006
Twenty one differences between CME-driven geomagnetic storms and CIR-driven geomagnetic storms are tabulated. (CME-driven includes driving by CME sheaths, by magnetic clouds, and by ejecta; CIR-driven includes driving by the associated recurring high ...
