Some features of the Antarctic ozone distribution and its variations are studied for a 30-year period (1979‒2008) of satellite measurements made with the TOMS and OMI satellite spectrometers. The changes of the ozone hole parameters are analysed and multi-year variations of the quasi-stationary planetary wave characteristics in the atmosphere over the Antarctic region are studied. The conclusion on stopping both the ozone level diminution and the ozone hole area increase since the late 1990s is made from the analysis of trends in the ozone hole characteristics.
            It is shown that the quasi-stationary waves cause the following: steady zonal asymmetry of the ozone distribution with ozone hole displacement relatively the South Pole into Atlantic longitudinal sector; a systematical eastward shift of the low ozone level region which is statistically reliable in the latitude range from 50 to 80° S and which reached 50° by longitude during the last 30 years. At the same time, a long-term change of the maximum position is insignificant. The retention of the regular eastward shift of quasi-stationary wave minimum during three decades is indicative of the existence of a dynamical factor changing the ozone hole asymmetry independently on tendencies in the ozone levels.
