ABNORMAL REVERSALS OF MERIDIONAL AND ZONAL EQUATORIAL ELECTROJET CURRENTS

From the analysis of equatorial electrojet data from the Indian sector , it has been shown that the eastward zonal current due to normal elec trojet is associated with a poleward meridional current. During period s of counter electrojet (westward zonal current), the meridional curre nt is reversed to equatorward direction. Thus, there is a component of zonal current identified with D or Y field which is an integral part of the equatorial electrojet current and not associated with global S- q. The total current in meridional direction at low latitudes is a mix ture of this equatorial electrojet associated current component over t he global-S-q associated meridional current.
