Through the analysis of meteorological elements collected at Comandante Ferraz
Antarctic Station (EACF) in 1997 (El Niño) and 1999 (La Niña), we studied the
behavior of themselves and their relationship with ENSO. In this work we used
meteorological data from the Antarctic Program (PROANTAR), which is based on
Antarctic Station Comandante Ferraz (EACF, Latitude 62 ° 05'S, Longitude 58 °
23'W) which is a pole with lines of scientific research in more various branches of
science, located in Antarctica. Were made hourly and monthly air temperature, soil
temperature, atmospheric pressure, precipitation, relative humidity and wind speed,
and made comparisons between the average years of study, with the measured data
of 3 in 3 hours (UTC). The results are in from those found in the literature to study
this type of area. Comparisons between means showed a significant increasing trend
in most variables in the year of La Niña Air temperature and soil, wind speed and
rainfall had significant increases. The other variables (atmospheric pressure and
relative humidity) showed an inverse pattern, which is seen as expected due
inversely proportional to the temperature of air, which showed a significant increase
in the year of El Niño to La Niña year.
