The problem of total ozone change rate estimation is discussed. The analysis of published data reveals contradictory facts. This paper is based on OMI satellite total ozone data for 2005-2015. The singular spectrum analysis is used for estimation of the ozone trends and seasonal variations. The trend analysis shows that ozone increased with a rate of 1.97% per decade in the Northern hemisphere midlatitudes; and 1.52% per decade in the South hemisphere. There was an anomalous decrease in ozone in the Southern hemisphere from August to December of 2015; a large ozone hole was formed. It is shown that one of the caused could be the circulation conditions: from the tropical latitudes to the South less ozone than usually was moved.
