Calculations with a chemical box model along air parcel trajectories between November 1991 to January 1992 show a build up of reactive chlorine in late December and early January, culminating in values of ClO x greater than 2.0 ppbv widespread in the vortex on 9 January 1992. These values are quantitatively comparable to the MLS satellite measurements of ClO. We discuss the chemistry occurring within the vortex, around the vortex edge and outside the vortex.
