摘      要：The ozone budget inside the middle stratospheric polar vortex （24-36 km） during the 2002-2003 Arctic winter is studied by analyzing Michelson Interferometer for Passive Atmospheric Sounding （MIPAS） satellite data.A comprehensive global chemical transport model （Model for Ozone and Related Chemical Tracers,MOZART-3） is used to analyze the observed variation in polar vortex ozone during the stratospheric sudden warming （SSW） *** MIPAS measurement and MOZART-3 calculation show that a pronounced increase （26-28 DU） in the polar vortex ozone due to the SSW *** to the weakening of the polar vortex,the exchange of ozone mass across the edge of the polar vortex increases substantially and amounts to about 3.0 × 10 7 kg according to MOZART-3 *** enhanced downward transport offsets about 80% of polar vortex ozone mass increase by horizontal transport.A ＂passive ozone＂ experiment shows that only ～55% of the vertical ozone mass flux in February and March can be attributed to the variation in vertical *** is also shown that the enhanced downward ozone above ～32 km should be attributed to the springtime photochemical ozone *** to the increase of air temperature,the NO x reaction rate increases by 40%-80% during the SSW *** a result,NO x catalytic cycle causes another 44% decrease in polar vortex ozone compared to the net ozone changes due to dynamical *** is also shown that the largest change in polar vortex ozone is due to horizontal advection by planetary waves in January 2003.
