Measurements of stratospheric water vapour over Australia (Mildura, 34°S 140°E) during the period 1977–1979 indicate a mean mixing ratio between 15 and 21 km of 2°4p.p.m.m. The record since 1973 shows a quasi‐biennial oscillation with a peak to peak amplitude of 2 p.p.m.m. in the 15–21 km height interval. The latter appears well correlated with 50–30 mb equatorial westerlies.
