Influence of atmospheric dynamics during events Secondary Effect of the Antarctic Ozone Hole on southern Brazil

Abstract. The purpose of this paper is to show how atmospheric dynamics behave during the occurrence of ozone-hole inflow events in Antarctica, especially in mid-latitude regions, such as southern Brazil, for 12 years of observation. The results showed that most events occur after the frontal systems pass through mid-latitude regions, highlighting the importance of this study for the southern region of Brazil.
