Energetic particle induced inter-annual variability of ozone inside the Antarctic polar vortex observed in satellite data

A regression model is used to attribute CCM modelled and observed changes in Antarctic total column ozone to halogen-driven chemistry prior to 1980.. Wintertime Antarctic ozone

Correlation of a time series (1992–2009) of vortex mean ozone mixing ratios in early winter at 525–575 K and a time series of the fraction of air in the vortex in early winter

Anomalies of air-sea CO 2 fluxes ( F ) computed with daily wind speeds ( u 10 ) and 1982–2005 mean of daily u 10 , plotted against the sea surface temperature (SST) anomalies in

Investigating the formation of particle volume in the summer Central Antarctic base- line aerosol further, an annual cycle in the total particle volume in these air masses is

ozone loss reaches 40–60 % and in the upper stratosphere where both models show 70 % ozone decrease (see Fig. In the polar areas of the lower stratosphere we obtain 70–80 %

in the following section we present a case study of stratospheric subsidence induced by the polar vortex at Ny-Ålesund and another case study of a deep stratospheric intrusion event

Using the tight correlation observed between PSC areas and total vortex ozone deple- tion and taking into account the decreasing amounts of ozone depleting substances, we predict
