Ozonloch-Entstehung: Jülicher entdecken Barrieren

Forscher klären Prozesse im entstehenden Ozonloch auf

(PresseBox) (Jülich, )
Atmosphärenforscher haben jetzt ein Phänomen entdeckt, das wesentlich zur frühen Entstehung des Ozonlochs beiträgt: Im Polarwirbel – dort bildet sich in jedem Winter das Ozonloch über der Antarktis – baut sich eine doppelte Transportbarriere auf. Sie verhindert den Luftaustausch zwischen der ozonreichen Umgebungsluft und der ozonarmen Schicht im Inneren des Wirbels. Stickstoff spielt bei diesem Vorgang ebenfalls eine wichtige Rolle. (Development of tracer relations and chemical ozone loss during the setup phase of the polar vortex, S. Tilmes et al., Journal of Geophysical Research, Vol 111)
