Australian weather bureau says El Nino developing
The SOI, an indicator of an El Nino, has been falling rapidly for the past two weeks, the bureau said on Wednesday.
A consistently negative SOI would point to the development of an El Nino, which can bring drought to Australia and weaken Asian monsoons, hurting crop and livestock production.
The SOI measures the pressure difference between the Pacific island of Tahiti and the Australian city of Darwin.
The bureau said that if warm conditions in the Pacific persisted, 2009 was likely to be considered an El Nino year.
