The Equatorial Ionospheric Anomaly and the Equatorial Electrojet


  • J. W. MacDougall


It is shown that for the American zone the F-region equatorial anomaly and the equatorial electrojet are highly correlated, whereas the anomaly and the Sq current system correlate poorly. A suggested explanation for the correlation is that the eastward electric field which drives the electrojet is also present in the F-region and there causes upward plasma flow.
