                         Ozone Hole and reach mid and low latitude areas like the South of 
                         Brazil forming a known phenomenon called Secondary Effects of the 
                         Antarctic Ozone Hole. One of these phenomena was observed on 
                         October, 13th, 2010, by OMI Spectrometer over Southern Space 
                         Observatory (29.42° S and 53.87° W), in S{\~a}o Martinho da 
                         Serra, Brazil. Stratospheric potential vorticity maps on 
                         isentropic surfaces and air mass backward trajectory using HYSPLIT 
                         model by NOAA confirmed the polar origin of the poor ozone air 
                         mass. A description of the synoptic weather system during the 
                         event was made by wind field daily average at 250 hPa level and 
                         Omega at 500 hPa, thickness between 1000 and 500 hPa levels and 
                         GOES 10 enhance satellite image. It was observed that the event of 
                         low ozone occurred at the same time as a high pressure pos frontal 
                         system was passing over the south of Brazil and the subtropical 
                         jet stream left the weather stable and without clouds. These 
                         actions favored the intrusion of the stratospheric air in the 
                         troposphere and helped the stratospheric air mass transport from 
                         the polar region to the South of Brazil.",
