The Middle and Upper Atmosphere Model has been used to simulate the middle atmosphere variability by changing the lower boundary conditions. For this purpose quasi steady-state simulations were performed for individual days around the sudden stratospheric warmings (SSWs) in January 2009 and 2012. The modelled time series reveal a qualitatively good agreement with reanalysis zonal wind with the observed one by reanalysis at the same height and latitude. A medium-range prediction of SSW events appears possible if planetary waves (PW) in the lower stratosphere are additionally assimilated in form of externally forced travelling PW.
