A Qualitative Study of the Ionospheric Weak Response to Super Geomagnetic Storms
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 ...

Width of plasmaspheric plumes related to the level of geomagnetic storm intensity [PDF]
Annales Geophysicae, 2022 The plume is a plasma region in the magnetosphere that is detached from the main plasmasphere. It significantly contributes to the dynamic processes in both the inner and outer magnetosphere.

A machine learning-based model for the next 3-day geomagnetic index (Kp) forecast
Frontiers in Astronomy and Space Sciences, 2023 The 3-day Kp forecast product is important and necessary for space weather forecasts. There is some essential information that can be obtained from the 3-day Kp forecast product, such as the start time of the geomagnetic storm, the maximum storm level ...

The Variation of Geomagnetic Storm Duration with Intensity [PDF]
Solar Physics, 2019 Abstract Variability in the near-Earth solar wind conditions can adversely affect a number of ground- and space-based technologies. Such space-weather impacts on ground infrastructure are expected to increase primarily with geomagnetic storm intensity, but also storm duration, through time-integrated effects.

A Detection Study of the Ionospheric Total Electron Contents Variations Using GPS Network [PDF]
Journal of Astronomy and Space Sciences, 2007 We established a regional ionospheric model for investigating ionospheric TEC (Total Electron Contents) variations over the Korean Peninsula during major geomagnetic storms.

Journal of Geophysical Research: Space Physics, 1994 After a brief review of magnetospheric and interplanetary phenomena for intervals with enhanced solar wind‐magnetosphere interaction, an attempt is made to define a geomagnetic storm as an interval of time when a sufficiently intense and long‐lasting interplanetary convection electric field leads, through a substantial energization in the magnetosphere‐

Remote Sensing, 2023 Geomagnetic storms are one of the leading causes of ionospheric irregularities, depending on their intensity. The 6–10 September 2017 geomagnetic storm, the most severe geomagnetic event of the year, resulted from an X9 solar flare and a subsequent ...

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 ...

A Study on the Characteristics of the Ionospheric Gradient under Geomagnetic Perturbations
Sensors, 2020 The Earth’s ionosphere is greatly influenced by geomagnetic activities, especially geomagnetic storms. During a geomagnetic storm, the ionosphere suffers many perturbations, leading to a spatial gradient that are neglected during geomagnetically ...
