Abstract

In this review, the recent additional knowledge about the physical processes in two broad areas of the equatorial electrojet are emphasized 1. (i) the local interactions of the neutral winds with the electrojet plasma which result in diverse but physically inter-related effects on the altitude structure of electric fields and currents, ionization convergences and the formation of blanketing E s layers and F -region ionization dynamics 2. (ii) the very sensitive responses of the equatorial electrojet to the complex auroral ionosphere-magnetosphere interaction processes. On both the aspects, a synthesis of the observational results and theoretical models and ideas is attempted. The factors which contribute to apparent contradictions in the morphological results on the equatorial ‘counter-electrojet’ are discussed along with the possible physical processes causing the ‘counter-electrojet’.
