A study of geomagnetic storms [PDF]
Geophysical Journal International, 1978 The interplanetary energy flux is estimated on the basis of the Poynting flux and its variations with the rate of energy dissipation in terms of: (1) the ring-current particle injection, (2) Joule dissipation in the ionosphere, and (3) auroral particle injection for 15 major geomagnetic storms.

Statistical study on interplanetary drivers behind intense geomagnetic storms and substorms
Earth and Planetary Physics, 2019 Geomagnetic storms and substorms play a central role in both the daily life of mankind and in academic space physics. The profiles of storms, especially their initial phase morphology and the intensity of their substorms under different interplanetary ...

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

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.

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.

Relationship Between Geomagnetic Storms and Auroral/Magnetospheric Substorms: Early Studies
Frontiers in Astronomy and Space Sciences, 2020 This paper describes a short story of how I learned in early days in space physics (1960–1970) that there are the direct and feed-back relationships between geomagnetic storms and auroral/magnetospheric substorms.

A New Method for Predicting Non‐Recurrent Geomagnetic Storms
Space Weather, 2023 Predicting non‐recurrent geomagnetic storms caused by Coronal Mass Ejection (CME) is important and necessary for space weather forecasting. Previous studies have shown that it is feasible to predict non‐recurrent geomagnetic storms by reconstructing ...

Space weather and dangerous phenomena on the Earth: principles of great geomagnetic storms forcasting by online cosmic ray data [PDF]
Annales Geophysicae, 2005 According to NOAA space weather scales, geomagnetic storms of scales G5 (3-h index of geomagnetic activity Kp=9), G4 (Kp=8) and G3 (Kp=7) are dangerous for satellites, aircrafts, and even for technology on the ground (influence on power systems, on ...
