As in the observed record, the termination of El Niño in the coupled IPCC-AR4 climate models involves meridional processes tied to the seasonal cycle. These meridional processes both precondition the termination of El Niño events in general and lead to a peculiar termination of extreme El Niño events (such as those of 1982–83 and 1997–98), in which the eastern equatorial Pacific warm sea surface temperature anomalies (SSTA) persist well into boreal spring/early-summer. The mechanisms… Expand

Spring persistence, transition, and resurgence of El Niño
We present a systematic exploration of differences in the spatiotemporal sea surface temperature (SST) evolution along the equatorial Pacific among observed El Nino events. This inter-El NinoExpand
Warm Pool and Cold Tongue El Nino Events as Simulated by the GFDL 2.1 Coupled GCM
Recent studies report that two types of El Nino events have been observed. One is the cold tongue (CT) El Nino, which is characterized by relatively large sea surface temperature (SST) anomalies inExpand
Contrasting the evolution between two types of El Niño in a data assimilation model
Simulation outputs were used to contrast the distinct evolution patterns between two types of El Niño. The modeled isotherm depth anomalies closely matched satellite sea surface height anomalies.Expand
Modelled Rainfall Response to Strong El Niño Sea Surface Temperature Anomalies in the Tropical Pacific

The Varied Impacts of El Niño–Southern Oscillation on Pacific Island Climates
AbstractEl Nino–Southern Oscillation (ENSO) drives interannual climate variability in many tropical Pacific island countries, but different El Nino events might be expected to produce varyingExpand

Definition of Extreme El Niño and Its Impact on Projected Increase in Extreme El Niño Frequency
During extreme El Nino events, the Intertropical Convergence Zone moves to the normally cold and dry east equatorial Pacific, resulting in a nonlinear rainfall increase with sea surface temperatureExpand

Second peak in the far eastern Pacific sea surface temperature anomaly following strong El Niño events
[1] The eastern Pacific sea surface temperature anomaly (SSTa) associated with El Nino usually peaks in December, January, and February, and decays in the ensuing months; sometimes, however, after aExpand


Influence of the Seasonal Cycle on the Termination of El Niño Events in a Coupled General Circulation Model
In this study, the mechanisms leading to the El Nino peak and demise are explored through a coupled general circulation model ensemble approach evaluated against observations. The results hereExpand
Abrupt termination of the 1997–98 El Niño in response to a Madden–Julian oscillation
The role of the Madden–Julian oscillation—a global atmospheric wave in the tropics that is associated with convective activity and propagates eastwards with a period of about 30–60 days (refs 1,Expand

The Termination of the 1997–98 El Niño. Part I: Mechanisms of Oceanic Change*

A feature of the end-phase of recent El Nino periods is thermocline shallowing to normal depths, in the central and eastern equatorial Pacific, before sea surface temperature (SST) returns to normal.Expand
