中文摘要:
      Nino指数和SOI是表征ENSO事件的两个主要特征值。根据Nino 3.4区指数变化,1950年以来共发生15次El Nino事件和11次LaNina事件。El Nino年,热带中、东太平洋上的岛屿及沿岸国家多暴雨洪涝,印度、印度尼西亚、澳大利亚等国家发生持续干旱,中国东北地区夏、秋季降水及年降水都偏少,江南地区降水偏多;太平洋和大西洋地区发生的热带风暴以及登陆中国的台风数都比常年偏少;加拿大西南部和美国北部暖冬,东亚夏季低温,中国常出现暖冬凉夏。La Nina年则基本上相反,赤道太平洋中、东部地区干旱少雨,西太平洋上的台风和大西洋飓风及登陆中国的台风明显增多,中国汛期主要雨带偏北,易出现热夏寒冬。
英文摘要:
      Ni o Index (Sea-Surface Temperature Indices) and SOI(the Southern Oscillation Index)are two main indices used in monitoring and defining and predicting ENSO events. Based on Ni o3.4 Index since 1950, 15 El Ni o events and 11 La Ni a events have been identified. An El Ni o events results in heavy rainfall, even floods in the equatorial central and eastern Pacific, South America and south China, but scarce rainfall even severe droughts in India, Indonesia, Malaysia, eastern Australia. At the same time, rainfall is reduced over northern area of east China in summer,autumn and all year, tropical cyclone frequencies in the Pacific and Atlantic and landing China typhoon frequencies are decreased. It is warm over southeast Canada and northern U.S.A in winter, low temperature over eastern Asia, warm in winter and cool in summer over China. But during La Ni a events, this results in droughts in central and eastern tropical Pacific, tropical cyclone or typhoon frequencies in the Pacific and Atlantic and landing China typhoon frequencies are increased . The rain band in China during the high-water season is to the north . It is hotter in summer and colder in winter over China.
