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 ...

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‐

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 ...

Short term Variability of the Sun Earth System: An Overview of Progress Made during the CAWSES II Period [PDF]
, 2015 This paper presents an overview of results obtained during the CAWSES II period on the short term variability of the Sun and how it affects the near Earth space environment. CAWSES II was planned to examine the behavior of the solar terrestrial system as

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.
