对于很多同学来说雅思阅读是一个非常困扰的问题，那么多做题是一个解决的办法，今天就和出国留学网的小编一起来了解一下雅思阅读素材：厄尔尼诺。
The research is published online in the journal Nature Geoscience（地球科学）. 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（鱼类）and ocean nutrient distributions（海洋营养分布）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（增强）.＂
