Effect that jet streams have on the vertical ozone distribution and characteristics of tropopause inversion layer in the far east region

A major event of Antarctic ozone hole influence in southern Brazil in October 2016: an analysis of tropospheric and stratospheric dynamics

“…The vertical fields (Fig. 7) for the days of analysis showed the presence of the jet stream at high levels, reaffirming the importance of this circulation for the vertical transport of chemical components such as ozone (Bukin et al, 2011).…”

“…Potential vorticity (PV) acts as a tracer of large-scale air-mass dynamics and behaves as a material surface where the potential temperature is conserved (Hoskins et al, 1985). In the lower region of the stratosphere, the lifespan of O 3 molecules is longer, which allows them to be used as tracers in the study of air-mass flows in the stratosphere-troposphere exchange (Bukin et al, 2011). Chubachi (1984) and Farman et al (1985) have reported massive destruction of ozone content during the spring in the Southern Hemisphere, which is currently known as the Antarctic ozone hole.…”

“…Such currents play an important role in the vertical distribution of ozone and are considered the main tropospheric pattern directly linked to the transport of ozone from the stratosphere to the troposphere. Thus, the ozone total column (OTC) depends on meteorological dynamic factors, which in turn depend on seasonal variations at a synoptic scale (Bukin et al, 2011). Understanding the patterns of both influences has become increasingly important to understand how these events occur and behave.…”

Weather Condition Associated With Influence of the Antarctic Ozone Hole Over South of Brazil on October 21th, 2011

“…Perez et al, 2000;Pinheiro et al, 2012, as well as the identification of the existence of a connection between the transport of air masses in the stratosphere and the troposphere weather condition, mainly by the performance of the tropospheric jet stream, where its displacement influence the vertical distribution of ozone content (Bukin et al 2011) and causes intrusion of stratospheric air into the troposphere (Stohl et al, 2003). Moreover, on the South of Brazil, similar to the way the present study, this type of event has occurred after the passage of a frontal system .…”

Análise Atmosférica Dos Eventos De Efeito Secundário Do Buraco De Ozônio Antártico Sobre O Sul Do Brasil Em 2012. Parte 2:verificação Sinótica Da Troposfera Durante Os Eventos

“…O principal padrão de circulação troposférico correlacionado ao transporte de ozônio estratosférico é a corrente de jato, que desempenha importante papel na distribuição vertical de ozônio (Bukin et al, 2011) e atua diretamente nas trocas entre a troposfera e a estratosfera (Tang e Prather, 2010;Manney et al, 2011a;Trickl et al, 2011).…”
