Simultaneous observations of meteors and the equatorial electrojet at Jicamarca
… along meteor trails deposited within the equatorial electrojet. It is suggested that trails at electrojet heights must carry intense transient currents that excite two-stream and/or gradient drift instabilities for irregularity growth. The direction of electron motion responsible for the …

Plasma turbulence in the equatorial electrojet observations, theories, models, and simulations
The plasma turbulence in the equatorial electrojet due to the presence of two different plasma instability mechanisms has been observed and studied for more than seven decades. The sharp density-gradient and large conductivity give rise to gradient-drift and Farley-Buneman instabilities, …

Long-term investigation of the lunar tide in the equatorial electrojet during stratospheric sudden warmings
… on the ionosphere can be observed even at equatorial latitudes. During SSW events, the connection between the polar stratosphere and the equatorial ionosphere is believed to be through the modulation of global atmospheric tides. These tides are fundamental for the ionospheric E-region wind …

Solar flare effects observed over Jicamarca during MST-ISR experiments
… suppressed due to D-region absorption. Also, the equatorial electrojet (EEJ) radar backscatter was suppressed. Radar echoes from 150 km region were observed throughout the events but showed an abrupt initial drop in altitude by about 10 to 20 km followed by a slow recovery of 1 to 2 hours. …
