An earlier suggestion by Martyn that the effective conductivity of the ionosphere in the dynamo theory is enhanced by polarization of the Hall current is examined in quantitative detail. General expressions are given for the conductivities of a thin ionized sheet oriented at an angle to a uniform magnetic field. The effective conductivity of such a (spherical) sheet surrounding the earth is shown to be greater than either the Pedersen or the Hall conductivities. The variation of conductivity… Expand

Electric Currents induced in an Anisotropic Ionosphere
Summary Transient variations of the geomagnetic field arising outside and beyond the lower layers of the ionosphere induce electric currents in these layers which considerably modify the fieldExpand
Effective height‐integrated conductivity of the ionosphere
The validity of the standard formulas for the height-integrated ionospheric conductivity for problems involving current flow between the magnetosphere and the ionosphere is examined. The problem ofExpand
A theory of electrostatic fields in a horizontally stratified ionosphere subject to a vertical magnetic field
A theory is developed to describe quantitatively the idea that in an ionized gas subject to an imposed magnetic field, such as the ionosphere, the lines of magnetic flux are approximatelyExpand
Effects of the strength of the geomagnetic main field strength on the dynamo action in the ionosphere
Effects of the strength of the geomagnetic main field on the electrodynamics of the ionosphere were studied. Electric conductivities of the ionosphere were estimated for the cases of three times,Expand

A numerical two-dimensional model of the equatorial electrojet has been calculated that fully allows for meridional ionospheric currents. This model yields stronger currents and a substantiallyExpand

Transmission of the electric fields to the low latitude ionosphere in the magnetosphere-ionosphere current circuit
The solar wind energy is transmitted to low latitude ionosphere in a current circuit from a dynamo in the magnetosphere to the equatorial ionosphere via the polar ionosphere. During the substormExpand

The theoretical electrostatic coupling between the dynamo region and the F region of the ionosphere is examined at non-polar geomagnetic latitudes. It is found that, under certain conditions,Expand

Certain observations indicate that the auroral electrojets are confined to the auroral arcs. A model of an arc is presented in which the height variation of the auroral ionization is taken intoExpand

Abstract The processes leading to the formation and destruction of negative ions in the upper atmosphere are considered in detail. Even if the former are improbably rapid, and the latter areExpand
