Abstract : The preliminary results of the investigation of the relation between F-scattering and pearl-type pulsations are presented. The data used here for the scattering and short-period pulsations (SPP) were taken from tellurograms and ionograms which were obtained in the laboratories of the Siberian Institute of Terrestrial Magnetism, the Ionosphere and the Propagation of Radio Waves associated with the Academy of Sciences of the USSR (SibIZMIR SO AN SSSR) during the period of the vernal equinox from 1959 through 1963. Basically an amplitude-frequency analysis was carried out. The results of the studies are presented in the form of tables and graphs. A comparison is given of the intensities and duration of the phenomena being investigated. (Author)
