The paper presents observations of atmospheric and ionospheric parameters during strong meteorological disturbances (storms) in the Kaliningrad region. The critical frequency of the F2 layer (foF2) and the total electron content (TEC) were observed at the station Kaliningrad (20 °E, 54.20 °N). Atmospheric pressure and wind were taken to be the atmospheric parameters under study. The analysis of ionospheric observations has shown that during meteorological storms the amplitude of diurnal variations in TEC decreases to 50 %; and in foF2, to 15 % as compared to quiet days. The revealed changes in ionospheric conditions during meteorological storms are regularly registered and represent a characteristic feature of the meteorological effect on the ionosphere.
