Analysis of the Data

The measurements of ozone for ground stations in the Antarctic continent and the ground stations between 1993-1994 on the meridional point Chile-Argentina (parallel 23º at 54º south) demonstrate a good correspondence between mensurations by satellite and the ground stations (see fig.1 and fig.2), this fact demonstrates that the configurations of the ozone distribution over the Antarctic continent and the south cone of America are correct. [4]

They were created the first computer tools in GrADS and MATLAB, using data of the NCEP/ NCAR, in order to get the characteristic searched profiles. [3]. The study of the dynamic instability of the ozone Antarctic hole is possible using representatives profiles.

The information on the decreases in the total ozone column over the West coast of South America have been available since 1978, principally during the summer season in the southern hemisphere [2]. The profile distribution of stratospheric ozone associated with the ozone depletion in the south cone of America, they evidence the relationship between the ozone-poor air masses coming from the polar Antarctic vortex from the south to north. The maps of ozone gotten by the satellites (TOMS), they have a high correlation with the maps gotten by the model for the air masses of coming from the polar Antarctic vortex.
