Current understanding of magnetic storms: Storm‐substorm relationships [PDF]
Journal of Geophysical Research: Space Physics, 1998 This paper attempts to summarize the current understanding of the storm/substorm relationship by clearing up a considerable amount of controversy and by addressing the question of how solar wind energy is deposited into and is dissipated in the constituent elements that are critical to magnetospheric and ionospheric processes during magnetic storms.

Occurrence of Equatorial Plasma Bubbles during Intense Magnetic Storms
International Journal of Geophysics, 2011 An important issue in low-latitude ionospheric space weather is how magnetic storms affect the generation of equatorial plasma bubbles. In this study, we present the measurements of the ion density and velocity in the evening equatorial ionosphere by the

Solar events and solar wind conditions associated with intense geomagnetic storms
Earth, Planets and Space, 2023 Intense magnetic storms pose a systemic threat to the electric power grid. In this study we examined the solar/interplanetary causes of such storms, their peak theoretical and observed intensities, and their occurrence frequency.

Nature, 1882 THE magnetographs at the Kew Observatory were a little disturbed from about 11 p.m. of the 13th inst. to 7 p.m. of the 14th inst. During the 15th they were quiet, and remained so up to 11.45 p.m. of the 16th, when the disturbance began by an increase of the declination, an augmentation of the horizontal force, and a diminution of the vertical force ...

Statistical Properties of Molecular Ions in the Ring Current Observed by the Arase (ERG) Satellite
Geophysical Research Letters, 2019 Molecular ions in the magnetosphere can be a tracer of fast ion outflows from the deep ionosphere. Statistical properties of molecular ions (O2+/NO+/N2+) in the ring current are investigated based on ion composition measurements (

The catalog of magnetic storms for Odessa magnetic anomaly zone
Odessa Astronomical Publications, 2018 On magnetic observatory "Odessa" since 1948 measurements of a magnetic field of Earth . At the same time measurements of three elements of a magnetic field are registered: horizontal component (H), vertical component (Z) and inducement (D). On the basis

Understanding the variability of magnetic storms caused by ICMEs [PDF]
Annales Geophysicae, 2017 In this paper, we study the dynamics of magnetic storms due to interplanetary coronal mass ejections (ICMEs). We used multi-epoch superposed epoch analyses (SEAs) with a choice of epoch times based on the structure of the events. By sorting the events
