TWO TYPES OF IONOSPHERIC STORMS,
Abstract
Phenomena observed in the ionosphere at the time of magnetic disturbances are discussed. On the basis of the material on ionospheric observations collected over a period of ten years (1946-1955) in the Tiksi bay, located near the zone of maximum auroral frequency, it is demonstrated that the relationship between the disturbances in the upper layers of the ionosphere (lowering of f sub o F2), and those in the lower layers (anomalous absorption) vary substantially from storm to storm. It was possible to isolate two types of storms: F-type storms, for which no noticeable increase of anomalous absorption is observed in the auroral zone in the presence of strong disturbances in the F2 layer, and the FD-type storms, in which a substantial increase of anomalous absorption was observed simultaneously with a decrease in f sub o F2.
