Description
For reasons not completely understood, in some years the anti-cyclone is lesspowerful than normal. The weaker winds it produces fail to draw cold waters upto the ocean's surface, thus opening the way for warm, nutrient-poor tropicalwaters. These changes in water temperature and climatic conditions are knownas El Nino.
