While some forecasting methods had limited SUCCESS predicting the 1997 E1 Nino a few months in advance, the Columbia University researchers say their method call predict large E1 Nonevents up to two years in advance. That would be good news for governments, farmers and others seeking to plan for the droughts and heavy rainfall that E1 Nino can produce in various parts of the world.
Using a computer the researchers matched sea-surface temperatures to later E1 Nio occurrences between 1980 and 2000 and were then able to anticipate E1 Nino events dating back to 1857, using prior sea-surface temperatures. The results were reported in the latest issue of the journal Nature.
The researchers say their method is not perfect, but Bryan C. Weare, a meteorologist at the University of California, Davis, who was not involved in the work, said it "suggests E1 Nino is indeed predictable."
"This will probably convince others to sear

[填空题]An El Nino causes a permanent change in the climate of the Atlantic Ocean, in the region around the equator.

[填空题]In an El Nino, the winds pushing the water around get weaker. As a result, some of the warm water piled up in the west slumps back down to the east, and not as much cold water gets pulled up from below.

El Nino is the term used for the period when sea surface temperatures are above normal off the South American coast along the equatorial Pacific, sometimes called the Earth’s heartbeat, and is a dramatic but mysterious climate system that periodically rages across the Pacific.
El Nino means "the little boy" or "the Christ child" in Spanish, and is so called because its warm current is felt along coastal Peru and Ecuador around Christmas. But the local warming is just part of an intricate set of changes in the ocean and atmosphere across the tropical Pacific, which covers a third of the Earth’s circumference. Its intensity is such that it affects temperatures, storm tracks and rainfall around the world.
Droughts in Africa and Australia, tropical storms in the Pacific, torrential rains along the Californian coast and lush greening of Peruvian deserts have all been ascribed to the whim of EI Nino. Until recently it has been returning a
A. its violence
B. its conditions
C. its regularity
