摘要: 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 chemical consequences of this event using Chemical Lagrangian Model Stratosphere (CLaMS). The initialization simulation is based on Halogen Occultation Experiment (HALOE) measurements. Because its nature, CLaMS well suited for simulating small-scale filaments that evolve during period. Filaments origin in midlatitudes were observed HALOE several times October 2002. results agree with these observations. further indicates a very rapid chlorine deactivation triggered warming associated vortex. Correspondingly, ozone depletion rates rapidly decrease to zero. Outside vortex, where air masses midlatitude transported ...
