Influence of the Eastern Pacific and Central Pacific Types of ENSO on the South Asian Summer Monsoon

Based on observational and reanalysis data, the relationships between the eastern Pacific(EP) and central Pacific(CP)types of El Ni?o-Southern Oscillation(ENSO) during the developing summer and the South Asian summer monsoon(SASM) are examined. The roles of these two types of ENSO on the SASM experienced notable multidecadal modulation in the late 1970s. While the inverse relationship between the EP type of ENSO and ...  (本文共17页) 阅读全文>>

Prediction of the Western North Pacific Subtropical High in Summer without Strong ENSO Forcing

The western North Pacific subtropical high(WNPSH) is one of the deterministic predictors of the East Asian summer climate, and a better prediction of the WNPSH favors more reasonable forecast of the East Asian summer climate. This study focuses on seasonal prediction of the WNPSH during neutral summers without strong El Ni?o–Southern Oscillation(ENSO) forcing, and explores the associated predictable sources, using th...  (本文共12页) 阅读全文>>

过去千年ENSO演化历史重建再分析

厄尔尼诺-南方涛动(El Ni1o-Southern Oscillation,简称ENSO)作为气候系统内部变率的最显著模态,对全球气候变化起到重要影响。利用珊瑚、树轮等气候代用记录对ENSO进行重建研究能够帮助我们认识气象仪器观测之前历史时期ENSO的变化规律,但由于气候代用记录和重建方法的不确定性导致目前对过去千年ENSO变化特征及其机理仍不明确。文章从气候代用记录和重建方法两方面对目前已公开发表的...  (本文共12页) 阅读全文>>

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>>
