Abstract. 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 ionosphere heights. Significant departures from regular courses of atmospheric and ionospheric parameters were detected in all analyzed data sets 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 usual westward before storm to eastward after storm. With this changes are connected changes in temperature where at 1 hPa 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 North and West components of ionospheric drift. Vertical component of plasma flow during the storm event is smaller with respect to corresponding values on preceding days.

Analyzed event of exceptionally fast cold front of the cyclone Fabienne fell into the recovery phase of minor-moderate geomagnetic storm observed as a negative ionospheric storm in European Mid-latitudes. Hence, ionospheric observations consist of both disturbances induced by moderate geomagnetic storm and effects originated in convective activity in troposphere. Nevertheless, taking into account significant change in global circulation pattern in the stratosphere, we conclude that most of the observed wave-like oscillations in the ionosphere during night 23–24 September can be straight attributed to the propagation of atmospheric waves launched on the frontal border (cold front) of the cyclone Fabienne. Frontal system acted as an effective source of atmospheric waves propagating upward up to the ionosphere.
