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

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

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
