“…According to the results given in Table 3, it is understood to be meaningful of the variables that the coefficients obtained from the models established for These results are in agreement with the fact that in the mesosphere-lower-thermosphere region, which is expressed in some previous studies [21][22][23], the processes coming from below and above are almost equally effective at an altitude of about 100 km. At the altitude of the work here is expected to be more dominant processes from above.…”

Abstract:In this study, the relationship between the neutral components (N 2 and O 2 ) in the E-region of the ionosphere (at 110 km altitude) for the Singapore (01.23 N; 103.55 E) station in the equatorial region and the F10.7 solar flux and z-component of Interplanetary Magnetic Field (IMF-Bz) was investigated. This relationship was determined by means of statistical multiple regression model. As a result, it was observed that the changes in F10.7 solar flux and IMF-Bz were inversely proportional to the changes in N 2 and O 2 . 92% and 83% of changes in N 2 and O 2 were found to be explained by F10.7 solar flux and IMF-Bz, respectively. When the F10.7 solar flux is changed by 1 s.f.u., it causes a decrease of 2.61×10 14 m -3 in N 2 and 2.96×10 14 m -3 in O 2 .Change of 1 nT in IMF-Bz causes a decrease of 9.95×10 15 m -3 in N 2 and 1.69×10 15 m -3 in O 2 .

“…Except for model studies there are observational evidences of consequent ionospheric disturbances attributed to dynamical processes in the lower atmosphere. Chernigovskaya et al (2018) provide evidence of an F2-layer ionospheric response to dynamic processes during the winter circumpolar vortex evolution in the strato-mesosphere. McDonald et al (2018) reported an enhancement in total electron content in the ionosphere, which coincides with the commencement of a stratospheric warming event.…”

“…Goncharenko et al (2010) observed persistent variations in the low-latitude ionosphere that occur several days after a sudden warming event in the high-latitude winter stratosphere. Enhancements of wave-like activity within the ionospheric F layer with relation to meteorological events were reported by Chernigovskaya et al (2015). Propagation of concentric gravity waves from the source region in the troposphere related to tropospheric convective storms up to the ionosphere was reported by Azeem et al (2015).…”

Abstract. A severe meteorological storm system on the frontal border of cyclone Fabienne passing above central Europe was observed on 23–24 September 2018. Large meteorological systems are considered to be important sources of the wave-like variability visible/detectable through the atmosphere and even up to ionospheric heights. Significant departures from regular courses of atmospheric and ionospheric parameters were detected in all analyzed datasets through atmospheric heights. Above Europe, stratospheric temperature and wind significantly changed in coincidence with fast frontal transition (100–110 km h−1). Zonal wind at 1 and 0.1 hPa changes from the usual westward before the storm to eastward after the storm. With this change are connected changes in temperature where at 1 hPa the analyzed area is colder and at 0.1 hPa warmer. Within ionospheric parameters, we have detected significant wave-like activity occurring shortly after the cold front crossed the observational point. During the storm event, both by Digisonde DPS-4D and continuous Doppler sounding equipment, we have observed strong horizontal plasma flow shears and time-limited increase plasma flow in both the northern and western components of ionospheric drift. The vertical component of plasma flow during the storm event is smaller with respect to the corresponding values on preceding days. The analyzed event of an exceptionally fast cold front of cyclone Fabienne fell into the recovery phase of a minor–moderate geomagnetic storm observed as a negative ionospheric storm at European mid-latitudes. Hence, ionospheric observations consist both of disturbances induced by moderate geomagnetic storms and effects originating in convective activity in the troposphere. Nevertheless, taking into account a significant change in the global circulation pattern in the stratosphere, we conclude that most of the observed wave-like oscillations in the ionosphere during the night of 23–24 September can be directly attributed to the propagation of atmospheric waves launched on the frontal border (cold front) of cyclone Fabienne. The frontal system acted as an effective source of atmospheric waves propagating upward up to the ionosphere.

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.
