Neutral thermospheric winds in the equatorial region provide the energy required to maintain the zonal equatorial electric field (EEF).In the E-region,tidal winds drive currents to higher
latitudes, which interact with the Earth’s magnetic field,causing a buildup of positive and negative charges at the dawn and dusk terminators,respectively.This causes a strong eastward electric field on the equatorial day-side(Forbes,1981;Heelis,2004). This electric field is a primary driver of many ionospheric phenomena
