We present the results of studying manifestation of atmospheric wave activity at the heights of the mesopause and ionospheric F2-region over Eastern Siberia, during winter sudden stratospheric warmings in February-March 2016 and February 2017. The study was carried out using experimental data on the rotational temperature of the hydroxyl molecule and on the peak electron density NmF2. We revealed a significant increase in the manifestation of the activity of atmospheric waves of different time scales in the upper atmosphere during the SSWs, and found the differences of the SSWs effects for the analysed events.
Keywords: wave activity, sudden stratospheric warming, atmosphere, ionosphere, temperature, peak electron density, mesopause, atmosphere-ionosphere coupling
