摘要：

The mesosphere and lower thermosphere are the least studied areas of the earth atmosphere. The reason for this is the lack of monitoring. We have instrument for measuring wind speed - the Fabry-Perot interferometer of the ISTP SB RAS which was used for study atmosphere dynamics in two winter periods - 2016/2017 and 2017/2018. Sudden stratospheric warming's (SSW) are investigated according to the ERA-Interim reanalysis archive. In 2017 and 2018, the interferometer data on wind speed at an altitude of 90 km showed a responses to the SSW, with different vertical and horizontal structure, which were occurred at the different of the quasi-biennial oscillation phases.
