      abstract     = {In September 2002, the Antarctic polar vortex was
                      disturbed, and it split into two parts caused by an
                      unusually early stratospheric major warming. This study
                      discusses the chemical consequences of this event using the
                      Chemical Lagrangian Model of the Stratosphere (CLaMS). The
                      chemical initialization of the simulation is based on
                      Halogen Occultation Experiment (HALOE) measurements. Because
                      of its Lagrangian nature, CLaMS is well suited for
                      simulating the small-scale filaments that evolve during this
                      period. Filaments of vortex origin in the midlatitudes were
                      observed by HALOE several times in October 2002. The results
                      of the simulation agree well with these HALOE observations.
                      The simulation further indicates a very rapid chlorine
                      deactivation that is triggered by the warming associated
                      with the split of the vortex. Correspondingly, the ozone
                      depletion rates in the polar vortex parts rapidly decrease
                      to zero. Outside the polar vortex, where air masses of
                      midlatitude origin were transported to the polar region, the
                      simulation shows high ozone depletion rates at the 700-K
                      level caused mainly by NO, chemistry. Owing to the major
                      warming in September 2002, ozone-poor air masses were
                      transported into the midlatitudes and caused a decrease of
                      midlatitude ozone by $5\%-15\%,$ depending on altitude.
                      Besides this dilution effect, there was no significant
                      additional chemical effect. The net chemical ozone depletion
                      in air masses of vortex origin was low and did not differ
                      significantly from that of midlatitude air, in spite of the
                      different chemical composition of the two types of air
                      masses.},
