摘要

摘要: 利用诊断分析方法分析研究了热带太平洋ENSO Modoki现象对南半球中高纬度气候和海冰的影响。分析了ENSO Modoki现象的季节变化特征，并定义了ENSO Modoki的活跃年和活跃季节。利用偏相关分析、合成分析和超前滞后相关分析等诊断分析方法，分析了1979年1月到2010年12月间ENSO Modoki影响南半球中高纬气候及海冰异常的遥相关模态及可能的遥相关动力机制。研究结果显示费雷尔环流的异常变化是两者之间遥相关的可能方式。

Abstract: By hiring CSD(climatological statistical diagnosis), the impacts of ENSO(El Nio-Southern Oscillation) Modoki on the middle and high latitude climate in the Southern Hemisphere and sea-ice anomalies of the South Pole are discussed. Active year and active months of ENSO Modoki are defined by combination of the former research and Modoki's seasonal variation. the CSD methods like correlation analysis, partial correlation analysis, composite analysis, lead-lag correlation analysis and so on are then imported to analyze meteorological elements field and ice data between January 1979 and December 2010. Through deep analysis and discussion, the teleconnection pattern and corresponding dynamic mechanism of ENSO Modoki are revealed. The result shows that there is an important relationship between ENSO Modoki and middle-high latitude climate and sea-ice anomalies in the Southern Hemisphere, the Ferrel Circulation is the most possible way of occurrence of teleconnection.
