It is likely that Australia will experience yet again the weather phenomenon El Niño in the coming months.

Although the indicators are still uncertain, Dr Andrew Watkins, from the climate prediction services of Australia's Weather Bureau, noted that five of their seven models have suggested the tendency of the re-emergence of an El Niño.

"Over the past several months, we've seen a warming of the central and eastern tropical Pacific Ocean and that's a pretty classic sign of a developing El Niño event," Dr Watkins said in ABC News.

"And if we continue to see warming we would expect to go into an event sometime in the later winter or even the spring."

In its Web site, the Bureau of Meteorology in July said that while indicators point to a less El Niño-like than they were a month ago, ocean surface temperatures continue to show a pattern, and in some places values, typical of the development stage of an El Niño. These indicators are the Southern Oscillation Index (SOI) and trade winds.

El Niño patterns, an abnormal warming of surface ocean waters in the eastern tropical Pacific, bring drier and hotter conditions and can result in drought. During El Niño events, large parts of eastern Australia are typically drier than normal during winter and spring, while southern Australian daytime temperatures tend to be warmer.

Its alternate La Niña weather pattern, on the other hand, for the past two years, had brought higher than average rainfall across northern and eastern Australia. La Niña is defined as cooler than normal sea-surface temperatures in the central and eastern tropical Pacific ocean.
