While some forecasting methods had limited success predicting the 1997El Nino a few months in advance, theColumbia University researchers say their method call predict largeEl 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 thatEl Nino can produce in various parts of the worlD、
Using a computer the researchers matched sea-surface temperatures to laterEl Nino occurrences between 1980 and 2000 and were then able to anticipateEl 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, butBryan
C、Weare. a meteorologist at the University ofCalifornia,Davis, who was not involved in the work, said it "suggests’El Nino is indeed predictable.’"
"This will probably convince others to search around more for even better methods." said Weare. He added that the new method "makes it possible to predictEl 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 1997El Nino, for example, caused an estimated $ 20 billion in damage worldwide, offset by beneficial effects in other areas, saidDavidAnderson, of theEuropeanCentre for Medium Range Weather Forecasts in ReadingEnglanD、The 1877El Nino, meanwhile, coincided with a failure of the Indian monsoon and a famine that killed perhaps 40 million in India andChina, prompting the development of seasonal forecasting,Anderson saiD、
WhenEl Nino hit in 1991 and 1997, 200 million people were affected by flooding inChina alone, according to a 2002 United Nations report.
While predicting smallerEl Nino events remains tricky, the ability to predict larger ones should be increased to at least a year if the new method is confirmeD、
El Nino tends to develop betweenApril and June and reaches its peak betweenDecember 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 majorEl Nino events in the next two years, although a weak warming toward the end of this year is possible.
