Equatorial scintillations in relation to the development of ionization anomaly [PDF]
Annales Geophysicae, 2006 The irregularities in the electron density distribution of the ionosphere over the equatorial region frequently disrupt space-based communication and navigation links by causing severe amplitude and phase scintillations of signals.

Effect of equatorial ionization anomaly on the occurrence of spread-F [PDF]
Annales Geophysicae, 1997 The unique geometry of the geomagnetic field lines over the equatorial ionosphere coupled with the E-W electric field causes the equatorial ionization anomaly (EIA) and equatorial spread-F (ESF).

Investigation of the response time of the equatorial ionosphere in context of the equatorial electrojet and equatorial ionization anomaly [PDF]
Annales Geophysicae, 2011 Equatorial Electrojet (EEJ) and Equatorial Ionization Anomaly (EIA) are two large-scale processes in the equatorial/low latitude ionosphere, driven primarily by the eastward electric field during daytime.

Variation of the Hemispheric Asymmetry of the Equatorial Ionization Anomaly with Solar Cycle
Journal of Astronomy and Space Sciences, 2019 In solstices during the solar minimum, the hemispheric difference of the equatorial ionization anomaly (EIA) intensity (hereafter hemispheric asymmetry) is understood as being opposite in the morning and afternoon.

On the relationship between the postmidnight thermospheric equatorial mass anomaly and equatorial ionization anomaly under geomagnetic quiet conditions [PDF]
Journal of Geophysical Research, 2011 The equatorial mass anomaly (EMA) in the thermosphere and equatorial ionization anomaly (EIA) in the ionosphere are two interesting phenomena in low-equatorial latitude regions. Previous studies have shown that the EMA appears between 1000 and 2000 local time (LT) and its location of trough is aligned with dip equator, indicating the plausible role of ...
