Spring variations in the Antarctic total ozone content are analyzed basing on satellite observation data. Deviations of the total ozone content distribution from zonally-symmetrical one are explained as the impact of large-scale Rossby waves propagating at the lower stratosphere heights. We consider the waves with zonal numbers 1‒3 which play a leading part in the high-latitude stratosphere. It is shown that the observed pattern corresponds to the Rossby wave dispersion relation with allowance made for zonal wind velocity.
