The convection electrojet and the substorm electrojet [PDF]
Annales Geophysicae, 1996 Enhancements in the auroral electrojets associated with magnetospheric substorms result from those in either the electric field or the ionospheric conductivities, or both.

Substorm behavior of the auroral electrojet indices [PDF]
Annales Geophysicae, 2004 The behavior of the auroral electrojet indices AU and AL during classical substorms is investigated by the use of global auroral images. A superposition of the 12 AE stations onto global auroral images and identification of the AL and AU contributing ...

Meridional equatorial electrojet current in the American sector [PDF]
Annales Geophysicae, 1999 Huancayo is the only equatorial electrojet station where the daytime increase of horizontal geomagnetic field (H) is associated with a simultaneous increase of eastward geomagnetic field (Y). It is shown that during the counter electrojet period when ∆

Can lower E-region dust particles be responsible for counter electrojet? [PDF]
Geofísica Internacional, 2008 Ablation of meteors leaves a large number of dust particles of sizes ranging from nanometers to several micrometers in the upper mesospheric region. These dust particles can affect the equatorial E-region conductivities in several ways.

Spatio-temporal development of large-scale auroral electrojet currents relative to substorm onsets [PDF]
Annales Geophysicae, 2022 During auroral substorms, the electric currents flowing in the ionosphere change rapidly, and a large amount of energy is dissipated in the auroral ionosphere.

Afternoon mid-latitude current system and low-latitude geomagnetic field asymmetry during geomagnetic storms [PDF]
Annales Geophysicae, 1997 For four geomagnetic storms of middle intensity the relationship between the low-latitude magnetic field asymmetry using ASY indices and the intensity of the auroral eastward and westward electrojet was considered.

Effect of the solar wind conditions on the ionospheric equivalent current systems [PDF]
Annales Geophysicae, 2013 We employ a global magnetohydrodynamics (MHD) model, namely the PPMLR-MHD model, to investigate the effect of the solar wind conditions, such as the interplanetary magnetic field (IMF) clock angle, southward IMF magnitude and solar wind speed, on the ...

Prompt penetration effects on Equatorial Electrojet from the Indian sector
Earth, Planets and Space, 2023 The morphology of prompt penetration effects (PP) in the Equatorial Electrojet (EEJ) at Vencode (VEN, Geomagnetic latitude 0.29ºN) was studied using 5-min samples of EEJ and interplanetary Ey component data from 2011 to 2015.

On the height variation of the E-region cowling conductivity – effect of charged dust particles [PDF]
Annales Geophysicae, 2006 Height profiles of the Cowling conductivity in the electrojet region, estimated using the atmospheric parameters given by the existing models like CIRA or MSIS and measured electron density profiles, consistently show the heights of the electrojet ...

Evidence and effects of a wave-driven nonlinear current in the equatorial electrojet [PDF]
Annales Geophysicae, 1997 Ionospheric two-stream waves and gradient-drift waves nonlinearly drive a large-scale (D.C.) current in the E-region ionosphere. This current flows parallel to, and with a comparable magnitude to, the fundamental Pedersen current.
