[1] A new ocean reanalysis that covers the period from 1871 to 2008 is used to explore the time-evolving characteristics of El Nino. The new reanalysis assimilates all available hydrographic and sea surface temperature data into a model of the global ocean forced with surface boundary conditions from an atmospheric reanalysis that also covers the period from 1871 through 2008. Using traditional measures of El Nino, our reanalysis shows that the timing of El Nino events is in agreement with sea… Expand
El Niño and El Niño Modoki variability based on a new ocean reanalysis
A new ocean reanalysis, covering the period from 1990 to 2009, is evaluated against observational sea surface temperature (SST) and sea surface height (SSH) data in reproducing the temporalExpand
Historical changes in El Niño and La Niña characteristics in an ocean reanalysis
[1] The variation of El Nino Southern Oscillation (ENSO) events from the mid-nineteenth century until the beginning of the twenty-first century is explored using an ocean reanalysis. A comparison ofExpand
El Niño Southern Oscillation in an ensemble ocean reanalysis and coupled climate models
[1] Long-term changes of El Nino/Southern Oscillation (ENSO) are studied using an ensemble ocean reanalysis that includes eight ensemble members from 1871 to 2008 and coupled model intercomparisonExpand
A study of response of thermocline in the South China Sea to ENSO events
This paper investigates the response of the thermocline depth (TD) in the South China Sea (SCS) to the El Niño-Southern Oscillation (ENSO) events using 51-year (from 1960 to 2010) monthly seawaterExpand
Robust contribution of decadal anomalies to the frequency of central-Pacific El Niño
The results suggest that decadal anomalies have an important contribution to the occurrence of the central-Pacific El Niño over past decades, and removing the decadal component leads to a significant reduction in the frequency of thecentral- Pacific El Niño in observations and in Coupled Model Intercomparison Project Phase 5 simulations of preindustrial, historical and future climate.

Influence of El Niño events on sea surface salinity over the central equatorial Indian Ocean.
The results indicate that the wind-driven anomalous zonal advection plays an important role in sea surface salinity variability during the El Niño events associated with the forcing from the anomalous Walker circulation over the equatorial Indian Ocean. Expand
Nonlinearities in the Evolutional Distinctions Between El Niño and La Niña Types
Using the HadISST, SODA reanalysis, and various other observed and reanalyzed data sets for the period 1950–2010, we explore nonlinearities in the subsurface evolutional distinctions between El NinoExpand
Contrasting the flavors of ENSO and related trends in the tropical Pacific Ocean in recent decades
The main features of the Eastern (EP) and Central (CP) Pacific El Nino Southern Oscillation (ENSO) events are analyzed using 1950-2010 observed and modeled data. Using various analysis techniques, weExpand
Does Extreme El Niño Have a Different Effect on the Stratosphere in Boreal Winter Than Its Moderate Counterpart
A robust impact of El Nino on the Northern Hemisphere (NH) polar stratosphere has been demonstrated by previous studies, although whether this applies to extreme El Nino is uncertain. The timeExpand
Revisiting El Niño Modokis
The suggestion that there exist two types of El Niño in the tropical Pacific has generated a debate in the community. Applying various linear and non-linear approaches and composite analysisExpand


El Niño Modoki and its possible teleconnection
[1] Using observed data sets mainly for the period 1979–2005, we find that anomalous warming events different from conventional El Nino events occur in the central equatorial Pacific. This uniqueExpand
Indices of El Niño Evolution
Abstract To characterize the nature of El Nino–Southern Oscillation (ENSO), sea surface temperature (SST) anomalies in different regions of the Pacific have been used. An optimal characterization ofExpand
The Energetics of El Niño and La Niña
Abstract Data from a realistic model of the ocean, forced with observed atmospheric conditions for the period 1953–92, are analyzed to determine the energetics of interannual variability in theExpand
El Niño in a changing climate
El Niño events, characterized by anomalous warming in the eastern equatorial Pacific Ocean, have global climatic teleconnections and are the most dominant feature of cyclic climate variability onExpand
Observations of Warm Water Volume Changes in the Equatorial Pacific and Their Relationship to El Niño and La Niña
Abstract This paper describes observed changes in surface winds, sea surface temperature (SST), and the volume of water warmer than 20°C (WWV) in the equatorial Pacific Ocean for the period 1980–99.Expand
A Simple Ocean Data Assimilation Analysis of the Global Upper Ocean 1950-95. Part II: Results
Abstract The authors explore the accuracy of a comprehensive 46-year retrospective analysis of upper-ocean temperature, salinity, and currents. The Simple Ocean Data Assimilation (SODA) analysis isExpand
Why the properties of El Niño changed during the late 1970s
Following the abrupt North Pacific climate shift in the mid-1970s, the period, amplitude, spatial structure, and temporal evolution of the E1 Nifio notably changed. Theory is needed to explain whyExpand
