Abstract In this study, two types of El Nino events are classified based on spatial patterns of the sea surface temperature (SST) anomaly. One is the cold tongue (CT) El Nino, which can be regarded as the conventional El Nino, and the other the warm pool (WP) El Nino. The CT El Nino is characterized by relatively large SST anomalies in the Nino-3 region (5°S–5°N, 150°–90°W), while the WP El Nino is associated with SST anomalies mostly confined to the Nino-4 region (5°S–5°N, 160°E–150°W).

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 in
Time-Spatial Features of Mix El Niño
The diversity of El Nino is a critical field of the climate research. The eastern Pacific (EP) and central Pacific (CP) types of El Nino have been identified in the previous studies. However, the
Simulation of two types of El Niño from different convective parameters
Many recent studies have reported the presence of two types of El Niño events in observation: Cold Tongue (CT) El Niño and Warm Pool (WP) El Niño. We investigate the sensitivity of a model simulating
Occurrence of two types of El Niño events and the subsurface ocean temperature anomalies in the equatorial Pacific
The relationships between the evolution of two types of El Niño events and the subsurface ocean temperature anomaly (SOTA) in the equatorial Pacific are compared in this study. The results show that
Impacts of variations in the strength and structure of El Niño events on Pacific rainfall in CMIP5 models
El Niño-Southern Oscillation (ENSO) plays a dominant role in interannual climate variability in Pacific island countries, directly affecting lives there. Many countries show different rainfall
Niño indices for two types of ENSO
El Niño‐Southern Oscillation (ENSO), which dominates variability on interannual timescale in the climate system, is known to exhibit various spatio‐temporal characteristics. Recent studies show that
Sensitivity Difference in the Extratropical Atmosphere to Two Types of El Niño Events
Abstract A comparison of sensitivity in extratropical circulation in the Northern Hemisphere (NH) and Southern Hemisphere (SH) is conducted through observational analyses and diagnostic linear model
A Comparative Analysis of the Impacts of Two Types of El Niño on the Central and Eastern Pacific ITCZ
The precipitation data from the Global Precipitation Climatology Project (GPCP) and CPC Merged Analysis of Precipitation (CMAP) were used to investigate the discrepancy of Centre and Eastern Pacific
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 on


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 unique
El Niño and La Niña sea surface temperature anomalies: Asymmetry characteristics associated with their wind stress anomalies
[1] The asymmetric nature of El Nino and La Nina sea surface temperature (SST) anomalies is investigated by the use of National Centers for Environmental Prediction reanalysis data and various ocean
Impact of El Niño onset timing on the Indian Ocean: Pacific coupling and subsequent El Niño evolution
A relation between the timing of the El Niño onset and its subsequent evolution is examined by emphasizing its association with the Indian Ocean (IO) SST variation. Two types of El Niño events based
The Role of the Asian–Australian Monsoon System in the Onset Time of El Niño Events
Abstract Based on the time of first occurrence of a significant sea surface temperature anomaly (SSTA) in the Nino-3.4 area (5°S–5°N, 170°–120°W), two types of El Nino episodes can be identified: the
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.
Preconditions for El Niño and La Niña onsets and their relation to the Indian Ocean
El Niño/La Niña onset is a challenging problem of ENSO prediction. In this study, we introduce two precursors of El Niño and La Niña onsets. One is the equatorial heat content, and the other is the
Interactive Feedback between ENSO and the Indian Ocean
Abstract A feedback process of the Indian Ocean SST on ENSO is investigated by using observed data and atmospheric GCM. It is suggested that warming in the Indian Ocean produces an easterly wind
Seasonal Dependence of the MJO-ENSO Relationship
Abstract Observations of the development of recent El Nino events suggest a pivotal role for the Madden–Julian oscillation (MJO). Previous attempts to uncover a systematic relationship between MJO
A relationship between timing of El Niño onset and subsequent evolution
A relationship between the timing of El Niño onset and the subsequent evolution is examined, using 130‐year long time series of Niño‐3.4 index from 1871 to 2000. It is found that El Niño events can
El Niño, La Niña, and the Nonlinearity of Their Teleconnections
The paradigm of an atmospheric system varying linearly with respect to extreme phases of the El Nino- Southern Oscillation is questioned. It is argued that the global response to tropical Pacific sea
