WELLINGTON (Reuters) - El Nino weather conditions, which can bring droughts to parts of Asia and affect crops, have emerged but will likely be weak and shortlived, New Zealand scientists said on Tuesday.
El Nino is a warming of sea surface temperatures in the tropical Pacific that occurs every four to 12 years and can have far-ranging effects around the globe, particularly on food output.
"Borderline El Nino conditions are present in the tropical Pacific, and a weak short-lived El Nino is predicted for the spring and summer periods," the National Institute of Water and Atmosphere said in its latest climate outlook.
