| Abstract: | A set of 17 rocket measured altitude profiles of the equatorial electrojet current density have been used to determine the parameters of a two-dimensional model of the equatorial electrojet with which the contours of equal current density of the electrojet have been constructed. The contours are in full agreement with contours by other workers constructed from wind models of the electrojet. They show the existence of return (westward) currents of the equatorial electrojet, on both flanks of the dip equator, extending from about 250 km to about 1000 km or more, with a peak at about 500 km–600 km from the dip equator, whose peak intensity is about 30% of the peak intensity of the eastward current at the dip equator. Other evidences of the westward current, the location and intensity of its peak have been mentioned. |
