SSRN Electronic Journal, 2009 The El Ninos Southern Oscillations (ENSO) is a periodical phenomenon of climatic interannual variability which could be measured through either the Southern Oscillation Index (SOI) or the Sea Surface Temperature (SST) Index. The main purpose of this paper is to analyze these two indexes in order to capture ENSO volatility.

The ENSO Signal in the Stratosphere
Annals of the New York Academy of Sciences, 2008Although the El Niño–Southern Oscillation (ENSO) is a tropospheric phenomenon, its effects are also observed in the stratosphere. Traditionally, the study of ENSO above the troposphere has been difficult because of the lack of global observations at high altitudes and also because of the presence of other sources of variability whose signals are ...

Two extended integrations of general circulation models (GCMs) are examined to determine the physical processes operating during an ENSO cycle. The first integration is from the Hamburg version of the ECMWF T21 atmospheric model forced with observed global sea surface temperatures (SST) over the period 1970–85.

ENSO diversity and the recent appearance of Central Pacific ENSO
Climate Dynamics, 2019ENSO diversity refers to the appearance in recent decades of different El Nino types in the tropical Pacific: In addition to the canonical El Nino, the newly discovered type, called Central Pacific (CP) El Nino, has its center of warming shifted more to the central equatorial Pacific.

The El Nino-Southern Oscillation (ENSO) is an interannual phenomenon involved in the tropical Pacific Ocean-atmosphere interactions. The oscillatory nature of ENSO requires both positive and negative ocean-atmosphere feedbacks. The positive feedback is dated back to Bjerknes' hypothesis in the 1960s, and different negative feedbacks have been proposed ...

The Southern Oscillation was named in 1924 and its discovery can be traced back to colonial attempts to forecast the Indian monsoon in the late-nineteenth century. The first use of the name ‘El Nino’ to describe a climatic phenomenon appeared in South America in 1893. The term did not, however, originally mean what it does today, being used to describe

ENSO and non-ENSO induced charging and discharging of the equatorial Pacific
Climate Dynamics, 2015It is well established that variations in extratropical North Pacific wind stress fields can influence the state of the tropical Pacific 12–15 months prior to the maturation of boreal winter El Nino/Southern Oscillation (ENSO) events. While most research has focused on accompanying variations in the North Pacific trade winds and underlying sea surface ...

Prediction Skill of ENSO and ENSO Teleconnections in NorCPM: A Comparative Analysis with C3S
Weather and ForecastingAbstract In recent decades, high demand from stakeholders and policymakers has intensified research efforts toward operational seasonal forecasts. This is particularly relevant when it comes to El Niño–Southern Oscillation (ENSO), the primary driver of year-to-year climate variability with global socioeconomic impacts.

Recent predictions of the El Nino/Southern Oscillation phenomenon have given indications that the onset of a warm event can be predicted as much as two years in advance. In this chapter these predictions will be reviewed, the dynamical mechanisms underlying the predictions will be discussed, and the relationship between mechanism and predictability ...
