International audience The long-term monitoring of Influence of the Antarctic Ozone Hole over South of Brazil events was carried out for the period of 35 years between 1979 and 2013 and the climatology and anomalies of the stratospheric fields were calculated when this type of phenomenon occurred. For this, the data of the total ozone column (TOC) was obtained by Brewer Spectrophotometers, installed at the Southern Space Observatory - SSO / CRS / INPE - MCTIC (29.4 °S, 53.8 °W, 488, 7 m) and the Total Ozone Mapping Spectrometer (TOMS) and Ozone Monitoring Instrument (OMI) satellite instruments, as well as the reanalysis II of the NCEP / DOE (National Centers for Environmental Prediction / Department of Energy) and retroactive trajectories by HYSPLIT ( HYbrid Single-Particle Lagrangian Integrated Trajectory) model. The methodology used was effective in identifying 62 events with a mean reduction of -9.35 ± 2.93% in the ozone content. In addition, the stratospheric circulation pattern was identified through mean fields and anomalies of potential vorticity, wind and temperature for the occurrence days of the phenomenon, with a wave displacement pattern embedded within a wide cyclonic circulation region, with predominantly southern winds is advected toward the south of Brazil.

Para isso, foram analisados os dados da coluna total de ozônio (CTO) obtidos através de Espectrofotômetros Brewer, instalados no Observatório Espacial do Sul - OES/CRS/INPE - MCTIC (29,4 °S; 53,8 °O; 488,7 m) e pelos instrumentos de satélite Total Ozone Mapping Spectrometer (TOMS) e Ozone Monitoring Instrument (OMI), além de parâmetros da reanálise II do NCEP/DOE (National Centers for Environmental Prediction/ Departament of Energy) e trajetórias retroativas do modelo HYSPLIT (HYbrid ...
