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 S q 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.
