Paper Abstract

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.
