October Antarctic temperature and total ozone trends from 1979-1985The morphology of temperature trends in the south polar stratosphere from 1979-1985 is detailed. A significant cooling has occurred in the stratosphere over this period. South polar October mean temperatures have declined 18 K at 24 km over the seven-year period. A large fraction of this decline occurs as a result of including 1979 temperatures in the trend. The years 1979 and 1982 differ from other years in that they include large mid-October wave events which produce significantly warmer polar temperatures. Nevertheless, a significant temperature decline has still occurred in the stratosphere even when the dynamically active years are not included. Comparing two relatively dynamically quiet years, 1980 and 1985, the largest temperature decrease in the 30 mb temperature field occurs not at the pole but in the subpolar temperature maximum centered near 60 deg S. The changes in temperature of both the maximum and the polar low regions correlate fairly well with total ozone changes observed by the Total Ozone Mapping Spectrophotometer.
