\nThe\u00a0El Ni\u00f1o climatic event has long been a driving factor in the way of life of the average Australian, especially if you live away from the city. Dry conditions spread across much of the country, and increase the likelihood of extreme bushfires. Now, a new study has found that any “flavour” of\u00a0El Ni\u00f1o can be detected 19 months in advance; that’s nine months earlier than was previously possible.<\/p>\n

The study was published in the journal\u00a0Nature Climate Change<\/em> and was led by\u00a0Ms Nandini Ramesh, of the Indian Institute of Science, in Bangalore. Ramesh, a pre-PhD student, is presently a researcher at the University of New South Whales Climate Change Research Centre.<\/p>\n

\"\"<\/a><\/p>\n

Nandini and colleague Raghu Murtugudde happened across their discovery while reviewing decades worth of climatic data relating to\u00a0El Ni\u00f1o events.<\/p>\n

Not all\u00a0El Ni\u00f1o events follow the same course once they start, nor do they all have the same severity. But according to\u00a0Nandini, they do all have the same tell-tale discharge of massive volumes of sub-surface warm water from the equatorial western Pacific Ocean. The process had not been noticed prior because it happens sub-surface, where msot satellite measurements take only the surface measurement.<\/p>\n

\u201cSatellite observations are only taking the ocean\u2019s skin-temperature, and it turns out that\u2019s not always a good indicator of what\u2019s happening in the top couple of hundred metres, which is a key driver of the El Ni\u00f1o cycle,\u201d says Ramesh.<\/p>\n

<\/p>\n

According to the University of NSW, the “warm\u00a0water accumulates in the equatorial western Pacific when driven there by persistent trade winds. The researchers say that once the discharge begins in June to August (in the northern hemisphere summer) of the year before the event, the warm water spreads eastward beneath the surface, roughly along the equator.”<\/p>\n

And this takes place in every\u00a0El Ni\u00f1o event, even if surface temperature patterns vary between events.<\/p>\n

\u201cWe still don\u2019t know what triggers the sub-surface discharge to begin in the first place, and it doesn\u2019t always result in an El Ni\u00f1o event,\u201d says Ramesh. \u201cBut we have confirmed that all El Ni\u00f1o events begin this way, which means we can be on the alert for them much, much earlier than before.<\/p>\n

\u201cThat\u2019s good news for farmers, fire authorities and anyone whose livelihood or wellbeing can benefit from advance warnings like this. It will also improve our theoretical understanding of global climate and how the El Ni\u00f1o cycle may respond to climate change.\u201d<\/p>\n
