對于很多同學來說雅思閱讀是一個非常困擾的問題，那么多做題是一個解決的辦法，今天就和出國留學網(wǎng)的小編一起來了解一下雅思閱讀素材：厄爾尼諾。
    The research is published online in the journal Nature Geoscience（地球科學）. El Nino is a periodic（周期的）warming in the eastern tropical Pacific that occurs along the coast of South America. Recently， scientists have noticed that El Nino warming is stronger in the Central Pacific rather than the Eastern Pacific， a phenomenon known as El Nino Modoki （Modoki is a Japanese term for ＂similar， but different＂）.
    Last year， the journal Nature published a paper that found climate change is behind this shift from El Nino to El Nino Modoki. While the findings of that paper are still being debated， this latest paper in Nature Geoscience presents evidence that El Nino Modoki drives a climate pattern known as the North Pacific Gyre Oscillation （NPGO）.
    ＂We＇ve found that El Nino Modoki is responsible for changes in the NPGO，＂said Emanuele Di Lorenzo， associate professor in the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. ＂The reason this is important is because the NPGO has significant effects on fish stocks（魚類）and ocean nutrient distributions（海洋營養(yǎng)分布）in the Pacific， especially along the west coast of the United States.＂
    The NPGO， first named two years ago by Di Lorenzo and colleagues in a paper in Geophysical Research Letters， explained for the first time long-term changes in ocean circulation of the North Pacific， which scientists now link to an increasing number of dramatic transitions in coastal marine（沿海海域）ecosystems.
    ＂The ecosystems of the Pacific may very well become more sensitive to the NPGO in the future，＂ said Di Lorenzo. ＂Our data show that this NPGO is definitively linked to El Nino Modoki， so as Modoki becomes more frequent in the central tropical Pacific， the NPGO will also intensify（增強）.＂
