A Dynamo Theory in the Ionosphere

Abstract

The differential equations of the dynamo theory are solved by numerical integration, taking into account of the daily variation of the anisotropic conductivity. It is shown that the observed wind in the E region is sufficient for the requirement of the dynamo theory. The drift of ionization is discussed and it is shown that at night some part of electrons in the lower F region will descend into the E region in the middle latitudes.
