Space Weather, Volume 24, Issue 6, June 2026.Abstract Techniques developed in the past few years enable the derivation of multiscale ion convection and particle precipitation patterns from high‐resolution ground‐based observations, and it has been shown in previous studies that such multiscale geomagnetic forcing can contribute significantly to ionospheric and thermospheric disturbances.

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

On the relationship between the velocity of E-region HF echoes and E B plasma drift [PDF]
, 2005 International audienceIn this study, velocities of E-region HF echoes observed by the Stokkseyri HF radar are compared with ExB plasma drifts in the F-region measured by the DMSP satellites.

Space Weather, Volume 24, Issue 6, June 2026.Abstract This study presents a detailed case study of the ionospheric impacts of moderate (G2) and severe (G4) geomagnetic storms over the Latin American sector, with particular emphasis on the formation and suppression of equatorial plasma bubbles (EPBs).

Theory of auroral electrojets [PDF]
Journal of Geophysical Research, 1963 Two mechanisms are described for the formation of electrojet currents in the auroral zone. Both mechanisms require the existence of magnetospheric convection in which only particles of relatively low energy participate. It is essential to both mechanisms that particles of one sign (positively or negatively charged) should predominate among the ...

Improving and testing the empirical equatorial electrojet model with CHAMP satellite data [PDF]
Annales Geophysicae, 2004 The longitudinal variation of the Equatorial Electrojet (EEJ) intensity has been revised including data from the equatorial station of Baclieu (Vietnam), where an unexpected enhancement of the EEJ magnetic effects is observed.

Space Weather, Volume 24, Issue 6, June 2026.Abstract Modern submarine communication cables, though fiber‐optic in nature, remain vulnerable to space weather hazards due to their internal conductive cables used for powering repeaters. During geomagnetic storms, variations in the geomagnetic field induce geoelectric fields that drive geomagnetically induced voltages along these cables.

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading
Space Weather, Volume 24, Issue 6, June 2026.Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

Equatorial Counter Electrojet & Interplanetary Magnetic Field [PDF]
, 1981 1-15The characteristics of equatorial counter electrojet events associated with the reversal of the Bz component of interplanetary magnetic field (IMF) are discussed and compared with those of events associated with semi-diurnal luni-solar tides.
