THE Bureau of Meteorology (BOM) reports this year’s La Nina event is slowly decaying.
While La Niña conditions remain, some indicators have weakened over the past fortnight, and the majority of climate models surveyed by the Bureau suggest a gradual decline of the current La Niña, with most models suggesting an end of the event during the coming autumn season.
Over the past fortnight, atmospheric indicators of La Niña, such as the Southern Oscillation Index (SOI), trade winds and cloudiness over the equatorial Pacific Ocean have shifted towards more neutral values, implying some weakening of the La Niña event.
Sea surface temperatures in the central and eastern tropical Pacific has also warmed slightly from their December lows.
