INVESTIGATING LARGE-SCALE TRAVELLING IONOSPHERIC DISTURBANCES ACCORDING TO OBLIQUE SOUNDING DATA
This research deals with morphological peculiarities of wave ionospheric disturbances with the period range between one and two hours and the spatial extent exceeding 1000 km. We used the oblique ionospheric sounding data obtained over Eastern Sibe­ria (Russia) during several month-long uninterrupted experiments over three radio paths from 2006 to 2010. Studied here are both large-scale travelling ionospheric disturbances generated during magnetic storms and large-scale wave ionospheric disturbances recorded during geomagnetically quiet periods of time. Along with large-scale travelling ionospheric disturbances, small-scale ionospheric structures were observed.
