Southern hemisphere climate patterns for autumn (March-May) 1992 are reviewed, with particular emphasis on Pacific Basin climate indicators, and on temperature and rainfall over Australia. The period commenced with atmospheric and oceanic conditions all consistent with a mature El Niño-Southern Oscillation (ENSO) event, but by May there were signs that the event was beginning to decline. Below average rainfall over northern and eastern Australia, and above average temperatures in the north, were typical of the mature phase of an ENSO event.
W. J. Wright (Wed,) studied this question.
