根据以下材料，回答{TSE}题 El Nino (厄尔尼诺现象) While some forecasting methods had limited SUCCESS predicting the 1997 E1 Nino a few months in advance, the Columbia University researchers say their method can predict large E1 Nino events 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 Nino occurrences between 1980 and 2000 and were then able to anticipate E1 Nino events dating back to1857, 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 itsuggestsE1 Nino is indeed predictable. This will probably convince others to search around more for even better methods. said Weare. He added that the new methodmakes it possible to predict E1 Nino at long lead times. Other models also use sea-surface temperatures, but they have not looked as far back because they need other data, which is only available for recent decades, Weare said. The ability to predict the warming and cooling of the Pacitic is of immense importance. The 1997 E1 Nino, for example, caused an estimated$20 billion in damage worldwide, offset by beneficial effects in other areas, said David Anderson, of the European Centre for Medium-Range Weather Forecasts in Reading, England. The 1877 E1 Nino, meanwhile, coincided with a failure of the Indian monsoon and a famine that killed perhaps 40 million in India and China, prompting the development of seasonal forecasting, Anderson said. When E1 Nino hit in 1991 and 1997,200 million people were affected by flooding in China alone, according to a 2002 United Nations report. While predicting smaller E1 Nino events remains tricky, the ability to predict larger ones should be increased to at least a year if the new method is confirmed. E1 Nino tends to develop between April and June and reaches its peak between December and February. The warming tends to last between 9 and 12 months and occurs every two to seven years. The new forecasting method does not predict any major E1 Nino events in the next two years,although a weak warming toward the end of this year is possible. {TS}The method used by the Columbia University researchers can predict E1 Nino a few months in advance.
