| Abstract | Este trabalho analisa a variabilidade do ozônio e suas relações com a dinâmica estratosférica sobre a América do Sul, utilizando análise harmônica das imagens TOMS do satélite Nimbus-7. As análises evidenciaram a maximização e a minimização da concentração de ozônio na primavera. A distribuição geral do ozônio estratosférico apresenta maior variabilidade nas altas latitudes e menor sobre as baixas latitudes. Observou-se que o ciclo anual é mais acentuado entre 30°S a 45°S e que o primeiro harmônico é mais acentuado em setembro. A variabilidade do ciclo anual apresentou um comportamento distinto em função da latitude, podendo ser identificados três domínios: tropical (25°S a 15°N), extratropical (25°S a 52°S) e subpolar (abaixo de 52°S). Além disso, observou-se que a oscilação QB está praticamente presente em todas as latitudes, especialmente nos subtrópicos e latitudes médias, mostrando uma significativa correlação entre os padrões de circulação do inverno e as combinações de fases da oscilação QB e os eventos de El Niño. Palavras-chave: Ozônio, ciclo anual, TOMS. ABSTRACT: This work deals with the annual variability of ozone and its association with the stratospheric circulation over South America. The methodology applied involves the use of Fourier analysis on TOMS (Total Ozone Mapping Spectrometer) images. The ozone amplitude shows large/small variability at high/low latitudes and is more prominent in September. The annual cycle reveals a distinct latitudinal behavior being possible to identify three main domains: tropical (15oS to 25oS), extratropical (25oS to 55oS) and subpolar (>55oS). In the first case the amplitudes are small around 10oS, and the maximization/minimization of first harmonic occurs during the austral spring/autumn. Within the extratropical domain, the highest amplitudes are found in middle latitudes over southeast Pacific Ocean and southwest Atlantic Oceans and north of 20oN. The variability of the annual ozone cycle in this region apparently is influenced by the polar vortex. The amplitudes are relatively smaller around 60oS and between 0 and 120oW where the maximum values occur in the austral spring. Regarding the interannual variability of the annual cycle, it is suggested that changes in ozone amplitude due to the quasi-biannual oscillation is present in all latitudes, particularly in tropical latitudes where it shows a connection with El Niño events. |
