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 (

Morphological aspects of a new type of counter electrojet event [PDF]
Annales Geophysicae, 1999 The study describes the time and space morphologies of a rather new type of counter electrojet event on the basis of data from the excellent chain of magnetic and ionospheric observatories along the Indo-Russian longitude sector.

Unveiling the combined effects of neutral dynamics and electrodynamic forcing on dayside ionosphere during the 3–4 February 2022 “SpaceX” geomagnetic storms [PDF]
Scientific Reports, 2023 Geomagnetic storms of G1-class were observed on 3 and 4 February 2022, which caused the loss of 38 out of 49 SpaceX satellites during their launch due to enhanced neutral density.

Equatorial Counter Electrojet Longitudinal and Seasonal Variability in the American Sector [PDF]
Journal of Geophysical Research: Space Physics, 2018 The equatorial electrojet occasionally reverses during morning and afternoon hours, leading to periods of westward current in the ionospheric E region that are known as counter electrojet (CEJ) events. We present the first analysis of CEJ climatology and

Variabilities of mesospheric tides and equatorial electrojet strength during major stratospheric warming events [PDF]
Annales Geophysicae, 2009 The present study demonstrates the relationship between the high latitude northern hemispheric major sudden stratospheric warming (SSW) events and the reversal in the afternoon equatorial electrojet (EEJ), often called the counter-electrojet (CEJ ...

Geophysical Research Letters, 2022 We present space‐ and ground‐based multi‐instrument observations demonstrating the impact of the 2022 Tonga volcanic eruption on dayside equatorial electrodynamics. A strong counter electrojet (CEJ) was observed by Swarm and ground‐based magnetometers on

Journal of Physics: Conference Series, 2019 In recent years, it has been clarified from previous studies that plasma bubbles and equatorial electrojets (EEJs) are related. In general, EEJs are calculated by subtracting the magnetic field H component of the magnetic equator from that at low ...

Variability of equatorial counter electrojet signatures in the Indian region [PDF]
Journal of Geophysical Research: Space Physics, 2017 AbstractThe limited longitudinal extent of equatorial counter electrojet (CEJ) has been inferred by several workers based on the analysis of ground data. However, the scale length of CEJ characteristics at 2 h or less has not been estimated so far. The present study seeks to characterize the longitudinal variability of CEJ phenomena at a longitudinal ...

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.
