The variable source of the plasma sheet during a geomagnetic storm [PDF]
Nature Communications, 2023 Both solar wind and ionospheric sources contribute to the magnetotail plasma sheet, but how their contribution changes during a geomagnetic storm is an open question.

A Qualitative Study of the Ionospheric Weak Response to Super Geomagnetic Storms [PDF]
Atmosphere, 2020 The ionospheric response to a geomagnetic storm is a geophysical process. Although strong geomagnetic storms input more energy into the Earth’s upper atmosphere, the ionospheric response often does not reflect the same level of variation as the ...

Unexpected major geomagnetic storm caused by faint eruption of a solar trans-equatorial flux rope [PDF]
Nature CommunicationsSome geomagnetic storms’ solar origins are ambiguous, making them hard to predict. On March 23, 2023, a severe geomagnetic storm occurred, however, forecasts based on remote-sensing observations failed to predict it.

Magnetospheric chaos and dynamical complexity response during storm time disturbance [PDF]
Nonlinear Processes in Geophysics, 2021 In this study, we examine the magnetospheric chaos and dynamical complexity response to the disturbance storm time (Dst) and solar wind electric field (VBs) during different categories of geomagnetic storm (minor, moderate and major geomagnetic storm ...

Morphology in the total electron content under geomagnetic disturbed conditions: results from global ionosphere maps [PDF]
Annales Geophysicae, 2007 Using 8-year global ionosphere maps (GIMs) of TEC products from the Jet Propulsion Laboratory (JPL), we make a statistical study on the morphology of the global ionospheric behaviors with respect to the geomagnetic disturbances.

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

Ionospheric redistribution during geomagnetic storms [PDF]
Journal 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) produced at the Jet ...

On extreme geomagnetic storms [PDF]
Journal 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
