abstract = "The present study aims to analyze the stratospheric dynamics of
the events of influence of the Antarctic Ozone Hole (BOA) that
occurred over the South of Brazil in 2016. To reach this goal,
days of reduction were used in the stratospheric ozone content
based on Total Ozone Column (CTO) daily average data obtained from
the Brewer spectrophotometer installed at the Southern Space
Observatory (OES/INPE) (29.443752 ºS, 53.823084 ºW; 488.7 meters)
and by the Ozone measuring instrument (Ozone Monitoring Instrument
- OMI) onboard the NASA Aura satellite. For those days,
stratosphere dynamics analyses were carried out through isentropic
fields of Potential Vorticity (PV) at 600 and 700 K (Kelvin)
levels of potential temperature, using the daily PV averages
obtained from ERAInterim reanalysis of ECMWF (European Center for
Medium-range Weather Forecast) to verify the origin of the
ozone-poor air masses. Thus, the confirmation of the origin of
these masses through the retroactive trajectories obtained using
the HYSPLIT model (Hybrid Single-Particle Lagrangian Integrated
Trajectory) of NOAA (National Oceanic and Atmospheric
Administration). In addition, images of the ozone content of the
OMI satellite were used as a complementary technique to verify the
performance of BOA over Southern Brazil. Then, 6 events of
influence of the Antarctic Ozone Hole were identified over the
South of Brazil in 2016, with an average reduction percentage of
11% of the CTO to monthly climatologies, confirmed by the passage
of stratospheric polar filaments over the OES region, observed in
the VP isentropic fields at the 600 and 700 K potential
temperature levels as well as by the retroactive trajectories of
polar origin obtained in the HYSPLIT model.",
