This paper attempts to determine effects of meteorological disturbances in variations of ionospheric parameters. Data from the NCEP/NCAR reanalysis project (2009) were used to study meteorological effects. The analysis allowed us to reveal periods of large-scale wave motions in the stratosphere at 10 mbar, mainly during cold seasons; they can be associated with the jet streams at lower heights, localised mainly at latitudes 50–80 N. The large-scale wave motions in the stratosphere were compared with ionospheric disturbances over Irkutsk. The ionospheric data were obtained from continuous measurements at the vertical sounding ionosonde DPS-4 in Irkutsk. The disturbances refer to deviations of the electron concentration maximum NmF2 from their median values.
