False-colour TIROS-N satellite image of the Earth,showing temperature anomalies in the troposphere during the 1983 Pacific "El Nino" event. Red areas correspond to regions where the temperature is higher than the long-term average,while blue areas indicate regions whose temperatures are lower than the long-term average. The red area over the Pacific,off the coast of South America,is associated with the El Nino wind patterns. This climatic phenomenon recurs roughly every ten years,causing major changes in ocean circulation and severely affecting climate and biological productivity.
