El Niño Southern Oscillation

El Niño describes 'the warm phase of a naturally occurring sea surface temperature oscillation in the tropical Pacific Ocean', southern oscillation refers to 'a seesaw shift in surface air pressure at Darwin, Australia and the South Pacific Island of Tahiti' and La Nina refers to the cooling phase of the same temperature oscillation that causes El Nino. This graphic shows how the El Nino phenomenon changed weather conditions in southern Africa in 1997-1998, and how the La Nina phenomenon changed weather conditions in the region in 1999-2000. The phenomena can cause dry and warm conditions in some areas and wet and cool conditions in others.
