      abstract     = {[1] Planetary waves drive the mean meridional circulation
                      of the stratosphere and at the same time facilitate
                      quasi-horizontal mixing of trace gases. This paper presents
                      significant day-to-day variability of stratospheric trace
                      gas fields associated with large planetary wave activity
                      observed during the second mission of the Cryogenic Infrared
                      Spectrometers and Telescopes for the Atmosphere (CRISTA)
                      experiment. Geopotential height data of the UK Met Office
                      show that the CRISTA-2 observations in the Southern
                      Hemisphere winter were made during a period of extremely
                      large amplitudes of both wave-1 and wave-2. The planetary
                      wave-1, usually a quasi-stationary feature, moved eastward
                      with the traveling planetary wave-2. The large amplitudes of
                      both wave-1 and wave-2 led to a significant displacement of
                      the edge of the polar vortex toward the tropics (down to 30
                      S). As a result of the large wave amplitudes and favorable
                      phase alignment, the anticyclone drawing up tropical air was
                      unusually strong, and thus considerable wave-induced trace
                      gas flux from the tropics toward midlatitudes was observed,
                      mainly in the form of a pronounced planetary-scale tongue
                      advected out of the tropics around the vortex and into the
                      anticyclone. Quantitative transport calculations based on a
                      sequential data assimilation system highlight the importance
                      of such transport events for trace gas eddy-flux in the
                      Southern Hemisphere winter stratosphere.},
