Aspects of magnetopause/magnetosphere response to interplanetary discontinuities, and features of magnetopause Kelvin-Helmholtz waves

Farrugia, C. J.; Gratton, Fausto Tulio Livio (Elsevier, 2011-01)

We describe (i) perturbations of the magnetopause/magnetosphere elicited by an interplanetary discontinuity and (ii) the production of Kelvin-Helmholtz waves on the magnetopause. These are two large topics, so for reasons ...

The θBn problem: Determination of local magnetic parameters of interplanetary shocks from in situ IMF dataThe θBn problem: Determination of local magnetic parameters of interplanetary shocks from in situ IMF data

González Esparza, J. Américo; Instituto de Geofísica, UNAM, México D.F., México.; Balogh, Andre; Blackett Laboratory, Imperial College, London, United Kingdom. (Instituto de Geofísica, 2012)

A study of phase-steepened Alfvén waves in a high-speed stream at 0.29 AU

Alexander, Pedro Manfredo (Copernicus Publications, 2000-08)

This work performs a search of phase-steepened Alfvén waves under a priori ideal conditions: a high-speed solar wind stream observed in one of the closest approaches to the Sun by any spacecraft (Helios 2). Five potential ...

Statistical analysis of discontinuities in solar wind ace data and comparison with intermittent mhd turbulence

Greco, A.; Matthaeus, W.H.; Servidio, S.; Chuychai, P.; Dmitruk, Pablo Ariel (IOP Publishing, 2009-12)

The comparison between Advanced Composition Explorer (ACE) solar wind data and simulations of magnetohydrodynamic (MHD) turbulence shows a good agreement in the waiting-time analysis of magnetic field increments. Similarity ...

Large amplitude perturbations and waves at the duskside LLBL of the magnetopause generated by an interplanetary tangential discontinuity on December 7, 2000

Gratton, Fausto Tulio Livio; Farrugia, C. J.; Bilbao, Luis Ernesto; Gnavi, Graciela Delia; Lund, E. J. (American Institute of Physics, 2006-12)

On December 7, 2000 a joint current sheet and vorticity layer hit the magnetopause (MP) generating large amplitude oscillations, and wave-like perturbations observed by CLUSTER at the near dusk flank. Linear stability ...

Unusually long lasting multiple penetration of interplanetary electric field to equatorial ionosphere under oscillating IMF Bz

Wei, Yong; Hong, Minghua; Wan, Weixing; Du, Aimin; Lei, Jiuhou; Zhao, Biqiang; Wang, Wenbin; Ren, Zhipeng; Yue, Xinan (American Geophysical Union, 2008-01-17)

During November 11–16, 2003, the interplanetary magnetic field (IMF) Bz oscillated between northward and southward directions, which suggests discontinuous magnetic reconnection associated with the multiple pulses‐like ...

Two-stage oscillatory response of the magnetopause to a tangential discontinuity/vortex sheet followed by northward IMF: Cluster observations

Farrugia, C. J.; Gratton, Fausto Tulio Livio; Lund, E.J.; Sandholt, P.E.; Cowley, S.W.H.; Torbert, R.B.; Gnavi, Graciela Delia; Mann, I.R.; Bilbao, Luis Ernesto; Mouikis, C.; Kistler, L.; Smith, C.W.; Singer, H.J.; Watermann, J.F. (Blackwell Publishing Ltd, 2008-12)

We discuss the motion and structure of the magnetopause/boundary layer observed by Cluster in response to a joint tangential discontinuity/vortex sheet (TD/VS) observed by the Advanced Composition Explorer spacecraft on 7 ...

The changing topology of the duskside magnetopause boundary layer in relation to IMF orientation

Lund, E.J.; Farrugia, C. J.; Sandholt, P. E.; Kistler, L. M.; Fairfield, D. H.; Gratton, Fausto Tulio Livio; Cowley, S. W. H.; Wild, J. A.; Mouikis, C. G.; Dunlop, M. W.; Reme, H.; Carlson, C. W. (Elsevier, 2006-01)

On 7 December 2000, Cluster made an extended outbound radial traversal of the duskside magnetopause boundary layer. The long duration of the crossing, during which Cluster spent several hours within 2RE of the nominal ...

Multi-spacecraft study of the January 21st 2005 ICME: Evidence of Current Sheet Substructure Near the Periphery of a Strongly Expanding, Fast Magnetic Cloud

Foullon, C.; Owen, C. J.; Dasso, Sergio Ricardo; Green, L. M.; Dandoureas, I.; Elliott, H.; Fazakerley, A. N.; Bogdanova, Y. V.; Crooker, N. U. (Springer, 2007-12)

We examine the near-Earth Interplanetary Coronal Mass Ejection (ICME) apparently related to the intense Solar Energetic Particle (SEP) event of 20 January 2005. Our purpose is to contribute to the understanding of the ...
