El Nino May Return as Pacific Ocean Shows Signs of Warming

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. 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.
