La Nina

Most of the observations and surveyed climate models of ocean temperatures and winds over the tropical Pacific Ocean indicate neutral El Niño-Southern ...

This pattern is likely to increase the chance of above average winter-spring rainfall for Australia.” “We’ve only seen that three times since the middle of last century.” It’s already received more than 126% of its average annual rainfall this year.

Meteorologists observed changes in trade winds, sea surface temperatures, and temperatures beneath the surface in the Pacific. Those factors indicated a move ...

About half the models the bureau surveys suggest a potential return to La Nina in spring, and back-to-back La Ninas is also not uncommon, Dr Watkins said. "But we also are aware that the models are suggesting we could go back into La Nina later in the year, and hence we've moved to La Nina watch," Dr Watkins said. "We also see quite warm temperatures in the oceans around Northern Australia and off Western Australia," Dr Watkins said.

The La Nina climate driver, which has been the key factor behind much of Australia's weather woes over the last two years, has finally ended.

La Nina has ended – but there’s a sting in the tail

The weather pattern that drove record rain and floods in eastern Australia this year has ended, but models suggest it may soon return.

"A third consecutive La Niña and could increase the chances of rain for an already saturated east coast," she said. - A climatologist says a third consecutive La Niña could increase the chances of rain for an "already saturated" east coast A triple La Niña has only happened three times before – in 1954-57, 1973-76 and 1998-2001 – according ARC Centre of Excellence for Climate Extremes climatologist Zoe Gillett.

This pattern is likely to increase the chance of above average winter-spring rainfall for Australia." "Rainfall predictions suggest Australia will continue to see above-average rainfall over the coming months," the WMO said in the global weather update. "A La Nina watch does not change the outlook of above average rainfall for most of Australia over coming months," Dr Watkins said. The official status for La Nina is now on "watch" which the bureau said is likely to be the pattern over winter. Plus the long-term predictions of above average rains for the rest of the year are still current. The third year of the La Nina influence has also been credited for some of the best farming seasons for decades.

And this helps put the tropical Pacific into a La Niña-like state. The authors found the collapse of this system – called the Atlantic meridional overturning circulation – would shift the Earth’s climate to a more La Niña-like state. About half the models the bureau surveys suggest a potential return to La Niña in spring, and back-to-back La Niñas is also not uncommon, Dr Watkins said. “A three-year La Nina is less common, and we’ve only seen that three times since the middle of last century.” “But we also are aware that the models are suggesting we could go back into La Niña later in the year, and hence we’ve moved to La Niña watch,” Dr Watkins said. The shift to La Nina watch does not change the outlook of above average rainfall for most of Australia over the coming months, with several other climate drivers affecting the country, Dr Watkins said.
