The behaviour of the Southern Hemisphere total ozone as measured by the TOMS family of sensors is studied using the Principal Component Analysis meted. The aim of the study is to determine the predominant structures in the distribution of the total ozone and the variability and trends since late 1978, when TOMS NIMBUS became operational. The results of the PC analysis are discussed to which are the dominant structures and variability with respect to the lower stratospheric temperature as measured MSU Channel 4 temperature retrievals. The role of changes in dynamics and chemistry on the variability of the ozone distribution is discussed.
