Circulatory Motions in the Ionospheric Atmosphere and their Relation to the S Field of the Terrestrial Magnetism. II

抄録

From a statistical research on virtual heights of the ionosphere for various locations, circulatory motions in the ionospheric atmosphere are assumed.
It is suggested by the dynamo theory from the assumption that the lower layer of the circulatory motions may produce S_q and the upper layer may produce S_D.
