What is a geomagnetic storm

Walter D. Gonzalez, +6 more
- 01 Apr 1994 - 
TL;DR: In this article, 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-ionosphere system, to an intensified ring current sufficiently strong to exceed some key threshold of the quantifying storm time Dst index.
Journal ArticleDOI

Postmidnight chorus: A substorm phenomenon

Bruce T. Tsurutani, +1 more
- 01 Jan 1974 - 
TL;DR: In this paper, the post-midnight chorus was detected in the midnight sector of the magnetosphere in conjunction with magnetospheric substorms and the characteristics of these emissions such as their frequency time structure, emission frequency with respect to the local equatorial electron gyrofrequency, intensity-time variation, and the average intensity were investigated.
Journal ArticleDOI

Origin of interplanetary southward magnetic fields responsible for major magnetic storms near solar maximum (1978–1979)

Bruce T. Tsurutani, +4 more
- 01 Aug 1988 - 
TL;DR: In this article, simultaneous ISEE-3 field and plasma data were used to examine interplanetary phenomena associated with 10 major magnetic storms detected from August 16, 1978, to December 28, 1979, in a study of Gonzalez and Tsurutani (1987), and, in particular, to determine the origins of the southward magnetic fields which caused the storms.
Journal ArticleDOI

Interplanetary origin of geomagnetic storms

Walter D. Gonzalez, +2 more
- 01 Apr 1999 - 
TL;DR: In this article, the authors examined the effects of a combination of a long-duration southward sheath magnetic field, followed by a magnetic cloud Bs event, and showed that double, and sometimes triple, IMF Bs events are important causes of such events.
Journal ArticleDOI

Corotating solar wind streams and recurrent geomagnetic activity: A review

Bruce T. Tsurutani, +13 more
- 01 Jul 2006 - 
TL;DR: In this paper, it was shown that geomagnetic storms associated with high-speed streams/CIRs will have the same initial, main, and recovery phases as those associated with ICME-related magnetic storms but that the interplanetary causes are considerably different.
