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.

Longitudinal variation of equatorial electrojet and the occurrence of its counter electrojet [PDF]
Annales Geophysicae, 2017 We examined the longitudinal variability of the equatorial electrojet (EEJ) and the occurrence of its counter electrojet (CEJ) using the available records of the horizontal component H of the geomagnetic field simultaneously recorded in the year 2009 (

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 ...

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 ∆

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.

Earth, Planets and Space, 2014 The auroral electrojet is enhanced in the polar ionosphere associated with charged particle precipitation and field-aligned currents during substorms. In this paper the geometry of the elctrojet is determined by using the ionospheric equivalent current systems for every 5 minutes during March 18 and 19, 1978.
