Abstract
The results of the modeling the anomalous behavior of the F 1 layer characteristics are presented. The anomaly lies in the jump-like variations in the critical frequency of the layer f 0 F1 and an abnormally large f 0 F1 value for the considered season and time. The observed effect is simulated based on the propagation of a large-scale travelling ionospheric disturbance. The quantitative values of the disturbance parameter are obtained and some peculiarities of its propagation are analyzed. The investigation was carried out with the help of the software for automated processing of the vertical sounding ionograms. The experimental data were obtained during the Radar-Progress project.
