Abstract

RECENTLY, Cowling and Borger1 have put forward theoretical reasons why the electric conductivity of the ionospheric D-region may be considerably less than that of the combined EF-regions. On the further postulate that tidal motions increase with height in the ionosphere, they conclude that a recent deduction2 concerning the origin of the solar and lunar magnetic variations is improbable.
