Temporal and spatial variations in ionospheric electron density profiles over South Africa during strong magnetic storms [PDF]

Natural Hazards and Earth System Sciences, 2013
Observations from the South African TrigNet global navigation satellite system (GNSS) and vertical total electron content (VTEC) data from the Jason-1 satellite were used to analyze the variations in ionospheric electron density profiles over South ...

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.

RESPONSE OF BIOLOGICAL SYSTEMS TO GEOMAGNETIC STORMS

Acta Biomedica Scientifica, 2018
At present, influence of weak magnetic fields associated with solar and geomagnetic activity on biological systems is gaining more interest. Taking into account the accumulated data on the influence of geomagnetic storms on different biological levels ...

A Semiring-based framework for fair resources allocation [PDF]

, 2008
This paper studies the probable roles of interplanetary and geomagnetic parameters in the generation of ‘intense’ and ‘very intense’ magnetic storms as well as the correlation between magnetic field B and flow speed V , southward turning of Bz (Bs ...

Geoeffectiveness and efficiency of CIR, Sheath and ICME in generation of magnetic storms

, 2011
We investigate relative role of various types of solar wind streams in generation of magnetic storms. On the basis of the OMNI data of interplanetary measurements for the period of 1976-2000 we analyze 798 geomagnetic storms with Dst < -50 nT and their ...

A quantitative assessment of empirical magnetic field models at geosynchronous orbit during magnetic storms [PDF]

, 2008
[1] We evaluate the performance of recent empirical magnetic field models (Tsyganenko, 1996, 2002a, 2002b; Tsyganenko and Sitnov, 2005, hereafter referred to as T96, T02 and TS05, respectively) during magnetic storm times including both pre- and post ...

Dependence of radiation belt flux depletions at geostationary orbit on different solar drivers during intense geomagnetic storms

Frontiers in Astronomy and Space Sciences, 2022
The loss of electron flux of the outer radiation belt has been widely studied in terms of the mechanism that brings in these losses. There are a few studies which have attempted to explain the interplanetary conditions that favor the depletions.

Relativistic electron flux growth during storm and non-storm periods as observed by ARASE and GOES satellites

Earth, Planets and Space, 2023
Variations of relativistic electron fluxes (E ≥ 1 MeV) and wave activity in the Earth magnetosphere are studied to determine the contribution of different acceleration mechanisms of the outer radiation belt electrons: ULF mechanism, VLF mechanism, and ...
