The paper investigates the impact of the neutral atmosphere dynamical processes on the high-midlatitude ionosphere during winter sudden stratospheric warming (SSW) in January 2009. For this purpose we use the ECMWF Era Interim reanalysis data and the data from high-midlatitude chain of Russian ionosonde stations. The results show that the ionospheric response to the SSW event at high-midlatitudes depends on the position of the ionosonde stations relatively to the stratospheric circulation jet-stream.
