Journal ArticleDOI
Observational evidence for an inside-out substorm onset scenario
TL;DR: In this paper, the authors present observations which provide strong support for a substorm expansion phase onset scenario in which a localized inner magnetospheric instability developed first and was later followed by the development of a Near Earth Neutral Line (NENL) farther down-tail.
Journal ArticleDOI
Initiation of ballooning instability in the near-Earth plasma sheet prior to the 23 March 2007 THEMIS substorm expansion onset
TL;DR: In this paper, the ballooning stability of the near-Earth plasma sheet prior to the initial expansion onset of the 23 March 2007 THEMIS substorm event was analyzed using OpenGGCM simulation.
Journal ArticleDOI
Structure, force balance, and evolution of incompressible cross‐tail current sheet thinning
M. H. Saito,D. H. Fairfield,Guan Le,L.-N. Hau,Vassilis Angelopoulos,J. P. McFadden,U. Auster,John W. Bonnell,Davin Larson +8 more
TL;DR: In this paper, the authors studied thinning of the current sheet in the near-Earth tail that led to the onset of a small substorm and presented a comprehensive explanation for the relationship between the thinning, the stretched structure, and development of intense current density.
Book ChapterDOI
Auroral Signatures of Ballooning Mode Near Substorm Onset: Open Geospace General Circulation Model Simulations
TL;DR: In this article, the authors investigated the relation between ballooning modes in the tail and auroral beads and found no direct connection between the ballooning mode and expansion phase onset.
Journal ArticleDOI
Effect of heat flux on Alfvén ballooning modes in isotropic Hall‐MHD plasmas
TL;DR: In this article, the authors apply the generalized Ohm's law in isotropic Hall-MHD equations and study the effect of heat flux on the ballooning modes under substorm circumstances.

Journal ArticleDOI
Nonlinear magnetohydrodynamics simulation using high-order finite elements
Carl Sovinec,Alan H. Glasser,T. A. Gianakon,Daniel C. Barnes,R. A. Nebel,Scott Kruger,Dalton Schnack,Steven J. Plimpton,A. Tarditi,Ming-Sheng Chu +9 more
TL;DR: In this article, a semi-implicit time-advance approach was used to simulate the growth rate of resistive tearing modes in 3D nonlinear non-ideal magnetohydrodynamics.
Journal ArticleDOI
Plasma sheet instability related to the westward traveling surge
Aurélien Roux,S. Perraut,Patrick Robert,A. Morane,Arne Pedersen,A. Korth,G. Kremser,B. Aparicio,D. Rodgers,R. J. Pellinen +9 more
TL;DR: In this article, a detailed analysis of an isolated dispersionless substorm is performed on the basis of field and particle data collected in situ by the geostationary satellite GEOS 2 and of data from ground-based instruments installed close to the GEOS2 magnetic footprint.
Journal ArticleDOI
Is steady convection possible in the Earth's magnetotail?
G. M. Erickson,Richard A. Wolf +1 more
TL;DR: In this paper, it is argued that the excess-pressure problem results from the general shapes of field lines in the inner and outer plasma sheet, and not from simple inaccuracies in all the magnetic field models.
Journal ArticleDOI
Current disruptions in the near-Earth neutral sheet region
A. T. Y. Lui,Ramon Lopez,Brian J. Anderson,Kazue Takahashi,L. J. Zanetti,R. W. McEntire,Thomas A. Potemra,D. M. Klumpar,E. M. Greene,Robert J. Strangeway +9 more
TL;DR: In this paper, the authors examined current disruption events observed by the Charge Composition Explorer during 1985 and 1986 and found that current disruption was accompanied by large magnetic field turbulence and frequently with reversal in the sign of the field component normal to the neutral sheet.
Journal ArticleDOI
Structure of the tail plasma/current sheet at ∼11 RE and its changes in the course of a substorm
TL;DR: In this paper, the authors used minimum variance analysis of the magnetic field variations during the crossings as well as finite ion gyroradius diagnostics to determine the orientation of the current sheet (CS) and then estimate the CS thickness.
