Abstract
The paper presents the results of observations the ionospheric parameters in Kaliningrad (54° N, 20° E) during a meteorological storm in the Baltic sea on October 2018. The analysis of ionospheric variations showed the increase in the total electron content reached 20 % relative to the averaged values, and the increase in the critical frequency of the F2 layer was 19 % during the storm. The increase in the amplitudes of ionospheric variations with periods of 6—20 min over the area of a meteorological storm was also revealed. The results of the numerical experiment on the disturbance of the upper atmosphere due to the observed variations in surface pressure also showed an increase in wave activity with periods of ~ 15 min and the formation of a large-scale disturbance at the heights of the thermosphere.
