The equations governing the equatorial electrojet are solved with the inclusion of winds due to gravity waves and observed winds in the day‐time. It is shown that the gravity wave winds modulate the electrojet significantly in the region 110‐150 km even at the dip‐equator. The results show that the stronger the wind shear, the more will be its effect on the electrojet. The local contribution of observed winds to the electrojet as reported by Rees et al (1975) seems to be an over‐estimate.
