An El Nino weather pattern, which can parch Australia and parts of Asia while bringing rains to South America, may occur in the coming months as the Pacific Ocean warms, according to Australia’s Bureau of Meteorology.
Most climate models suggest the tropical Pacific will warm through the southern autumn and winter, the bureau said in a statement today. Some models predict this warming may approach El Nino thresholds by early winter, it said. Australia’s autumn runs from March to May and winter is from June to August.
El Ninos, which are caused by the warming of the Pacific, affect weather worldwide and can roil agricultural markets as farmers contend with drought or too much rain. An El Nino trend is likely to develop this year, Gavin Schmidt, deputy director of NASA’s Goddard Institute for Space Studies in New York, said this month. It’s been almost five years since the last event, which typically occurs every two to seven years, according to Indonesia’s Meteorological, Climatology and Geophysics Agency.
