On the rotation of the polar ionospheric regions

Open publisher page 0 citations
Abstract
The possibility of magnetic coupling between the polar regions of the earth's ionosphere and the interplanetary gas has led to the suggestion that the polar ionosphere may not rotate with the earth. The depth to which the effects of the interplanetary drag might penetrate is examined here with the aid of two simple models. The results are not conclusive, but they do indicate that heights as low as the E region may be involved.
