Modeling the dynamics of the inner magnetosphere during strong geomagnetic storms
TL;DR: Tsyganenko et al. as discussed by the authors developed a dynamical model of the storm-time geomagnetic field in the inner magnetosphere, using space magnetometer data taken during 37 major events in 1996-2000 and concurrent observations of the solar wind and interplanetary magnetic field (IMF).
Journal ArticleDOI
THEMIS observations of an earthward-propagating dipolarization front

TL;DR: In this paper, a dipolarization front was detected in the central plasma sheet sequentially at X = -20.1 R E (THEMIS P1 probe), at x = -16.7 R E(P2 probe), and at X= -11.0 RE (P3/P4 pair), suggesting its earthward propagation as a coherent structure over a distance more than 10 R E at a velocity of 300 km/s.
Journal ArticleDOI
Dipolarization fronts as a signature of transient reconnection in the magnetotail
TL;DR: In this paper, it is shown that bipolarization fronts (DFs) form when the force balance is already restored in the system and justify their interpretation as a nonlinear stage of the tearing instability developing in two magnetotail-like structures on the left and on the right of the initial central X-line.
Journal ArticleDOI
Dipolarization fronts as a consequence of transient reconnection: In situ evidence
Huishan Fu,Huishan Fu,Jinbin Cao,Yu. V. Khotyaintsev,M. I. Sitnov,Andrei Runov,S. Y. Fu,Maria Hamrin,Mats André,Alessandro Retinò,Y. D. Ma,Haoyu Lu,X. H. Wei,Shiyong Huang +13 more
TL;DR: In this article, the authors show Cluster observation of bipolarization fronts inside the reconnection diffusion region, which provides in situ evidence of the second mechanism: Transient reconnection can produce bipolarization front.
Journal ArticleDOI
Magnetospheric configurations from a high-resolution data-based magnetic field model
TL;DR: In this article, the authors used a sum of orthogonal basis functions of different scales to reproduce arbitrary radial and azimuthal variations of the geomagnetic field, including its noon-midnight and dawn-dusk asymmetries.
