Abstract

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.
- Modoki,
- middle and high latitude climate anomaly in Southern Hemisphere,
- sea-ice anomaly,
- teleconnection
