TLDR
In this paper, a coupled ocean-atmosphere general circulation model is used to investigate the climatic shift of El Nino in the Holocene, which simulates a reduced ENSO intensity in the early and mid Holocene.Abstract:
A coupled ocean-atmosphere general circulation model is used to investigate climatic shift of El Nino in the Holocene. The model simulates a reduced ENSO intensity in the early and mid- Holocene, in agreement with paleoclimate record. The ENSO reduction is proposed to be caused by both an intensified Asian summer monsoon and a warm water subduction from the South Pacific into the equatorial thermocline.read more

TL;DR: The authors used selected proxy-based reconstructions of different climate variables, together with state-of-the-art time series of natural forcings (orbital variations, solar activity variations, large tropical volcanic eruptions, land cover and greenhouse gases), underpinned by results from GCMs and Earth System Models of Intermediate Complexity (EMICs), to establish a comprehensive explanatory framework for climate changes from the mid-Holocene (MH) to pre-industrial time.

Climate over past millennia
Philip Jones,Michael E. Mann +1 more
TL;DR: This paper reviewed evidence for climate change over the past several millennia from instrumental and high-resolution climate "proxy" data sources and climate modeling studies and concluded that late 20th century warmth is unprecedented at hemispheric and, likely, global scales.

TL;DR: Annual banded corals from Papua New Guinea are used to show that ENSO has existed for the past 130,000 years, operating even during “glacial” times of substantially reduced regional and global temperature and changed solar forcing, and it is found that during the 20th century ENGSO has been strong compared with E NSO of previous cool and warm times.

Atmospheric teleconnections from the equatorial pacific1
TL;DR: In this article, it was shown that the strong response of the northeast Pacific westerlies to big positive anomalies of equatorial sea temperature, observed in the winter of 1957-58, has been found to repeat during the major equatorial Sea temperature maxima in the winters of 1963-64 and 1965-66.

Variations in Tropical Sea Surface Temperature and Surface Wind Fields Associated with the Southern Oscillation/El Niño
TL;DR: In this article, the evolution of sea surface temperature (SST) anomalies, surface wind fields, and precipitation anomaly patterns during major warm episodes in the eastern and central tropical Pacific are described in terms of composite SST and wind fields (30°N−30°S) for six warm episodes since 1949, and time series and cross-spectral analyses of mean monthly data along six shipping lanes which cross the equator between the South American coast and 170°W.

Monsoon and Enso: Selectively Interactive Systems
Peter J. Webster,Song Yang +1 more
TL;DR: In this article, the authors attempt to construct a logical framework for the deciphering of the physical processes that determine the interannual variability of the coupled climate system and propose that the springtime is a period where errors may grow most rapidly in a coupled ocean-atmosphere forecast model or there are other influences on the system that are not included in the simple coupled-model formulations.

A Model El Niño–Southern Oscillation
Stephen E. Zebiak,Mark A. Cane +1 more
TL;DR: In this article, a coupled atmosphere-ocean model is developed and used to study the ENSO (El Niñ/Southern Oscillation) phenomenon, which reproduces certain key features of the observed phenomenon including the recurrence of warm events at irregular intervals with a preference for three to four years.
