Southern hemisphere circulation patterns and associated anomalies for the austral autumn (March to May) 2000 are reviewed, with emphasis given to the Pacific Basin climate indicators, and Australian rainfall and temperature patterns. During autumn the La Niña event, which had been in progress since spring of the previous year, came to an end. This was indicated by values of the Southern Oscillation Index and indices of sea-surface temperature in the tropical Pacific Ocean.
R. J. B. Fawcett (Fri,) studied this question.
