Abstract

Trends in total ozone for the period 1963–1974 at Australian stations Darwin, Brisbane, Aspendale and Macquarie Island have been discussed. Only Aspendale has a decreasing trend, which may be statistically significant. Trends in ozone at other places are not statistically significant.

From the trend analysis of temperature at the 100mb level, and from Umkehr analysis, it is concluded that the changes in circulation in the lower stratosphere are sufficient to explain the observed trends.

## Abstract The cause of the observed mid‐latitude decline in ozone in a 20‐year integration of a stratospheric chemical transport model forced by European Centre for Medium‐Range Weather Forecasts analyses for the years 1979 to 1998 is investigated. A very simple chemical scheme for ozone is used

## Abstract Results are presented of measurements of stratospheric water vapour over Mildura (34Β°S 140Β°E) Australia. The mean mixing ratio between 15 and 21 km is approximately 2–7ppm and is closely approximated below 15km by an exponential profile with a height constant of 2–4km.
