Seasonal linkage of the Southern Hemisphere extratropical climate variability to two types of ENSO

This study uses the Climate Forecast System Reanalysis(CFSR) to investigate the responses of the Southern Hemisphere(SH) extratropical climate to two types of El Ni?o–Southern Oscillation(ENSO)—the eastern Pacific(EP) type and the central Pacific(CP) type in different seasons. The responses are denoted by the anomalies of climate variables associated with one-standard-deviation increase in the Ni?o3 or Ni?o4 index. T...  (本文共11页) 阅读全文>>

A brief review of ENSO theories and prediction

Although the El Ni?o-Southern Oscillation(ENSO) originates and develops in the equatorial Pacific, it has substantial climatic impacts around the globe. Thus, the ability to effectively simulate and predict ENSO one or more seasons in advance is of great societal importance, but this remains a ch...  (本文共16页) 阅读全文>>

江苏省夏季暴雨的时空变率特征及其与不同类型ENSO的联系

利用1961—2016年江苏省70个站点的逐日降水资料和暴雨定义,分析了江苏省半个世纪以来暴雨发生的年代际时空变化特征,并分析了不同分布型El Ni?o发展年份对江苏省夏季降水和暴雨的影响特征。结果表明江苏省暴雨主要集中在6—8月,暴雨日数占全年的73.6%,尤其...  (本文共11页) 阅读全文>>

Modulation of the Intraseasonal Variability of Pacific–Japan Pattern by ENSO

This study investigates how the El Ni?o–Southern Oscillation(ENSO) modulates the intraseasonal variability(ISV) of Pacific–Japan(PJ) teleconnection pattern. The PJ index during boreal summer is constructed from the empirical orthogonal function(EOF) of the 850-hPa zonal wind(U850) anomalies. Distinct periods of the PJ index are found during El Ni?o and La Ni?a summers. Although ISV of the PJ pattern is significant du...  (本文共13页) 阅读全文>>

热带-热带外海洋对2000年后ENSO预测技巧的贡献(英文)

本文利用1979–2017年的再分析逐月资料,首先探讨了2000年前后ENSO海温(Ni?o3.4指数)与太平洋和其他海域的ENSO海温前兆信号(WWV:VM:vSPQ:NTA SST)之间的关系变化。结果表明由于热带太平洋信号WWV自身方差的骤减, WWV在2000年后并不能在超前...  (本文共8页) 阅读全文>>
