“…Based on the theoretical studies [59,61,83] and observational data [7,15,16,30,48] presented above, it is clear that the observed changes in TEC values during meteorological storms were caused by the local heating of the thermosphere due to dissipation of AGWs propagating to the upper atmosphere from the region of meteorological disturbances in the lower atmosphere.…”

“…It can be assumed that the reasons for such ionospheric effects may be associated with the processes of horizontal plasma transfer from the region of a large-scale thermospheric disturbance that formed above the epicenter of a meteorological storm located north of Kaliningrad. For example, in the observations presented in [15,16], it was shown that positive ionospheric effects occur at the southern border of the zone of meteorological disturbances. In October 2017, the meteorological storm began at 06 UT on 29 October and lasted until 23:00 UT (Figure 3a).…”

“…Spatial scales up to several hundred kilometers and existence times from several hours to 1-2 days depend on the intensity, duration, and scale of the event [4][5][6][7][8][9][10][11][12][13]. Monitoring less intense events also shows their impact on the upper atmosphere, although the effects in these cases are less pronounced [11,[14][15][16].…”

This paper presents the observations of ionospheric parameters in Kaliningrad (54° N, 20° E) during a meteorological storm in the Baltic Sea during October 2017 and 2018. Analysis of the total electronic content (TEC) during the storm showed that perturbations of the TEC values from the median can reach two standard deviations of the value. For the critical frequency of the F2 layer, it was 1.5–1.6 times the standard deviations. On days of a meteorological storm, significant changes were noted in the dynamics of the E-layer’s critical frequency. The reasons for the occurrence of the observed phenomena were due to the propagation of acoustic-gravity waves generated by convective processes in the lower atmosphere during periods of a meteorological storm. Spectral analysis of TEC variations revealed an increase in the amplitudes of ionospheric variations 10–16 min over the area of a meteorological storm. The analysis allowed us to conclude that ionospheric perturbations during the meteorological perturbation were caused by increased acoustic-gravity wave (AGW) generation processes in the lower atmosphere. The most likely cause of negative ionospheric disturbances were processes associated with the dissipation of AGW propagating from the area of a meteorological storm and increased turbulence in the lower thermosphere.

“…According to experimental data [1][2][3][4][5][6][7], the upper atmosphere and ionosphere response appear several hours after the disturbances occur near the Earth's surface. The changes in the ionospheric plasma parameters caused by seismic events were observed several days or more before the earthquakes.…”

The Influence of Tropospheric Processes on Disturbances in the D and E Ionospheric Layers

Determination of the physical mechanisms of the energy transfer of tropospheric disturbances to the ionosphere is one of the fundamental problems of atmospheric physics. This article presents the observational results of tropospheric and ionospheric disturbances during the passages of the solar terminator and solar eclipse. Lidar observations showed the occurrence of tropospheric regions with noticeably increased amplitudes of density, pressure, and temperature variations with periods corresponding to acoustic and internal gravity waves, which were generated in the troposphere during the development of these events. Simultaneous satellite measurements demonstrate the response of the ionosphere to these tropospheric disturbances. Based on the experimental data, we determine the typical periods and spatial scales of variations. It is shown that the response time of the ionosphere to tropospheric disturbances is 30–40 min.

“…The sources of such waves in the lower atmosphere may be different. For example, it may be the mesoscale turbulence, convection [5,11], disturbances arising in the atmosphere due to stationary incoming air streams flowing around mountains (orography effects) [12,13], earthquakes and seismic activity [7,14,15], the passage of the solar terminator and solar eclipse [16][17][18][19][20], meteorological disturbances and typhoon [1,[21][22][23][24][25][26][27][28][29].…”

Disturbances of the Thermosphere and the Ionosphere during a Meteorological Storm

et al. 2021

Determination of the physical mechanisms of energy transfer of tropospheric disturbances to the ionosphere is one of the fundamental problems of atmospheric physics. This article presents the results of observations carried out using two-wavelength lidar sensing at tropospheric altitudes and satellite GPS measurements during a meteorological storm in Kaliningrad (Russia, 54.7° N, 20.5° E) on 1 April 2016. During lidar sensing, it was found that the amplitudes of variations in atmospheric parameters with periods of acoustic (AWs) and internal gravity (IGWs) waves significantly increased. As a result of numerical modeling using the AtmoSym software package, it was shown that there is a noticeable increase in the period of temperature disturbances from 6–12 min to 10–17 min at altitudes from 150 km up to 230 km during the vertical propagation of acoustic waves and internal gravity waves from the troposphere. Nonlinear and dissipative processes in this layer lead to the formation of sources of secondary waves in the thermosphere with periods longer than those of primary ones. In this case, the unsteady nature of the wave source and the short duration of its operation does not lead to significant heating of the thermosphere. Simultaneous satellite observations demonstrate the response of the ionosphere (total electron content (TEC) disturbance) to tropospheric disturbances. Analysis of the time series of the amplitudes of the reflected lidar signal and TEC made it possible to determine that the response time of the ionosphere to tropospheric disturbances is 30–40 min.
