Abstract: 

Our understanding of the major chemical, physical and dynamic processes in the stratosphere and their complex interactions is reviewed with particular emphasis on the processes affecting the distribution of ozone in the atmosphere. Ozone observations made in New Zealand are used to portray features of the annual and longer term variations of total and vertical ozone distributions typical for a mid-latitude station. An example is shown of the short-term spring-time total ozone variations typical of the "sudden warming" phenomena in the Antarctic stratosphere. The theoretically predicted long-term ozone depletion trends due to pollution of the stratosphere, and the possible effects of the El Chichon volcanic eruption and the El-Nino Southern Oscillation event on the observed ozone anomalies in New Zealand and Antarctica during 1980-83 are discussed.
