RESUMO:

The tropical region has incidence of practically constant solar radiation all year, which makes it the region with the largest production of stratospheric ozone. However, due to the circulation Brewer-Dobson region has low column values Total Ozone - CTO. For the Southern Hemisphere, the largest CTO values are in middle latitudes during the spring months. In 1985, a large depletion in the ozone content is identified in the atmosphere of Antarctica, becoming known as "Antarctic ozone hole." Such "ozone hole" may be deformed or even free air masses with low concentration ozone, due to the instability of the vortex. This can cause anomalies in the concentration of ozone at mid-latitudes during the austral spring, are the Side Effects of Ozone Hole Antarctic - ESBOA. This work purpose is to define the dynamic evolution of the Total Ozone Column over the Southern Hemisphere during episodes of ESBOA. Analysis are conducted between 2004 and 2015, the data of OMI sensor. It is created a comma effect identification rate in the Antarctic vortex from the analysis of selected cases below the threshold for ESBOA. Later, analysis will be made of the cases selected by the index, through fields as potential vorticity, wind, temperature, pressure, for various levels of the atmosphere, in order to find relations stratosphere / troposphere. We selected 18 days below the threshold for ESBOA, four dates are outside the pattern seen in the others. For dates were 14 observing the point effect.
