In this paper we briefly describe the processes which lead to the formation of the Antarctic ozone hole, the attributes of the 1994 hole in comparison with previous years and the trends in hole severity. The 1994 hole was similar to the severe holes of recent years with values of below 100 DU observed. The season’s distinguishing features were abnormally high ozone values in mid-latitudes and a strongly asymmetric hole in late October. The hole appears to have peaked in severity due to the fact that all of the ozone in the 13 to 20 km region is being destroyed. The outlook for the future is for a slow recovery over the next 30 years as the chlorine and bromine loadings gradually decrease.
