A quasi 16‐day oscillation is discovered in the E‐ and F‐regions of the equatorial ionosphere during January/February 1979, apparently connected with the upward penetration of a free Rossby mode excited in the winter stratosphere. The observed effects are interpreted in terms of electric fields induced by the ionospheric wind dynamo.
