The equatorial counter electrojet: Part of a worldwide current system?
Geophysical Research Letters, 2002 The method of natural orthogonal components was applied to the ground geomagnetic data in the Central Asian sector (72–83°E), during the summer months of 1995, in an attempt to identify additional current systems that are superposed on the normal Sq current vortex and related to the equatorial counter electrojet (CEJ).

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Plasmaspheric plume hiss plays a crucial role in shaping Earth's electron radiation belts and influencing magnetosphere–ionosphere energy coupling. However, its generation mechanism remains contested between cyclic‐linear and localized‐nonlinear models. By analyzing over 64,000 high‐resolution plume hiss wave segments from the Van Allen Probes

Equatorial electrojet and radio scintillations
, 1983 It is shown that the day-time scintillations of VHF radio waves at the equatorial station, Huancayo, are very small, of the order of 1-2 dB peak, during the equatorial electrojet condition. If the event of complete or partial counter-electrojet occurring

Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract Solar activity is usually characterized by different indices from different perspectives, which are commonly interconnected and contain nonstationary oscillations (NSOs). Given the significant influence of solar activity on space weather, the Earth and humans, it is of great significance to predict solar activity for better understanding not ...

2‐Day Ionospheric Oscillations at Low Latitudes Due To an Ultra‐Fast Kelvin Wave
Earth and Space ScienceThis study establishes an observational connection between an ultra‐fast Kelvin wave (UFKW) and the occurrence of counter electrojet (CEJ) in the equatorial E region and planetary wave‐like oscillations in low‐latitude total electron content (TEC), based
