A climate analysis of the southern hemisphere for the austral autumn (March 1990 to May 1990) is presented with more detailed treatment of the Australian region. In the equatorial Pacific, autumn sea-surface temperatures were mainly near normal. Other equatorial climate indices were also tending towards normality during the season. In mid-latitudes, sea-surface temperature anomalies were generally positive, notably in the Australian region. A strong three-wave pattern was evident at middle to high latitudes, with strong pressure-height anomalies. Record rains and floods occurred over inland eastern Australia.
D. Gaffney (Fri,) studied this question.
