Ring current ions and radiation belt electrons during geomagnetic storms driven by coronal mass ejections and corotating interaction regions
TL;DR: In this paper, the authors conducted epoch analyses of ring current (RC) ions and radiation belt (RB) electrons for geomagnetic storms with Dst −130 nT associated with corotating interaction regions (CIRs), and CME-driven great storms with dst 3.5 during the recovery phase.
Journal ArticleDOI

TL;DR: In this article, the authors compare the geomagnetic effects of CIR-associated storms with those of 159 other CIRs observed during 1996-2005, and find that the major storms form the extreme tail of a continuous distribution of the CIR geoeffectiveness which peaks at Dst ∼ −40 nT but is subject to a prominent seasonal variation of ∼ 40 nT which is ordered by the spring and fall equinoxes and the solar wind magnetic field direction toward or away from the Sun.

TL;DR: In this paper, a computer simulation of the wave-particle interactions between the lower-band chorus (LBC) waves and electrons was conducted to show that scattering by propagating whistler simultaneously causes both the precipitations of sub-relativistic electrons and the pulsating aurora.
