Paper Abstract

Based on results derived from analyzing ioniospheric radio sounding data over Irkutsk, it is show that characteristics of climatic trends are seriously influenced by variations with periods of about 8 years. These variations can lead to a disturbance of the connection of ionospheric F-layer formation heights with solar activity. The origin of these variations is unclear to date. When such variations arise, there is an increase in the connection between variations of the formation heights of the F-layer and sporadic layers. An indicator of the occurrence of variations with an 8-year period is provided by the lowering of the formation heights of sporadic Es-layers, with sporadic structures of type 'c' and 'l' coexisting on the ionogram.
