[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 warming in the central equatorial Pacific associated with a horseshoe pattern is flanked by a colder sea surface temperature anomaly (SSTA) on both sides along the equator. empirical orthogonal function (EOF) analysis of monthly tropical Pacific SSTA shows that these events are represented by the… 

Anomalous tropical ocean circulation associated with La Niña Modoki

[1] El Nino Modoki is a variant of El Nino characterized by warming around the dateline flanked by anomalous cooling in the east and west. However, the opposite phase (La Nina Modoki) has received

Modoki, Indian Ocean Dipole, and western North Pacific typhoons: Possible implications for extreme events

[1] An interesting feature during El Nino Modoki summers (June–August) is the occurrence of surplus rainfall anomalies over the South China Sea (SCS) and off-equatorial tropical Northwest Pacific.

Processes and boreal summer impacts of the 2004 El Niño Modoki: An AGCM study

The sea surface temperature anomalies (SSTA) of tropical Pacific in the boreal summer of 2004 show a distinct tripolar pattern with warm SSTA in the central tropical Pacific, flanked on both sides by

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 analysis

The El Niño-Southern Oscillation (ENSO) Modoki signal in the stratosphere

El Nino-Southern Oscillation (ENSO) is known to be the largest source of interannual variability in the tropical troposphere. However, the variability in the tropical Pacific since 1979 seems to be

Central pacific El Niño, the "subtropical bridge," and Eurasian climate

[1] This study contributes to the discussion on possible effects of El Nino on North Atlantic/European regional climates. We use NCEP/NCAR reanalysis data to show how the two different types of El

The asymmetric impacts of ENSO modoki on boreal winter climate over the Pacific and its rim

The El Niño–Southern Oscillation (ENSO) Modoki phenomenon has a substantial influence on regional climate. In this study, the results derived from observational and reanalyzed datasets show that the

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, we

Cross-equatorial winds control El Niño diversity and change

Over the past two decades, El Niño events have weakened on average and their sea surface temperature (SST) anomalies shifted westward towards the central Pacific. Moreover, the intertropical



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 of

Long-term El Niño-Southern Oscillation (ENSO)-like variation with special emphasis on the South Pacific

Mechanisms for El Nino-Southern Oscillation (ENSO)-like decadal (7–35 years) variability are analyzed using observational data. When a decadal positive temperature anomaly occurs in the eastern

The Years of El Niño, La Niña, and Interactions with the Tropical Indian Ocean

Abstract The Indian Ocean zonal dipole is a mode of variability in sea surface temperature that seriously affects the climate of many nations around the Indian Ocean rim, as well as the global

Evolution of El Niño–Southern Oscillation and global atmospheric surface temperatures

[1] The origins of the delayed increases in global surface temperature accompanying El Nino events and the implications for the role of diabatic processes in El Nino–Southern Oscillation (ENSO) are

An unusual coupled mode in the tropical Pacific during 2004

The sea surface temperature anomalies (SSTA) of tropical Pacific in the boreal summer of 2004 show a tripolar pattern with warm SSTA in the central tropical Pacific flanked on both sides by cold

North American Precipitation and Temperature Patterns Associated with the El Niño/Southern Oscillation (ENSO)

Abstract This paper describes an investigation of the “typical” North American precipitation and temperature patterns associated with the El Nino/Southern Oscillation (ENSO). Monthly surface

Nonlinearity and Asymmetry of ENSO(.

El Nino events (warm) are often stronger than La Nina events (cold). This asymmetry is an intrinsic nonlinear characteristic of the El Nino-Southern Oscillation (ENSO) phenomenon. In order to measure

ENSO variability, teleconnections and climate change

An overview is presented of the principal features of the El Niño–Southern Oscillation (ENSO) teleconnections in terms of regional patterns of surface temperature, precipitation and mid‐tropospheric

Atmosphere-Warm Ocean Interaction and Its Impacts on Asian-Australian Monsoon Variation*

Abstract Asian–Australian monsoon (A–AM) anomalies depend strongly on phases of El Nino (La Nina). Based on this distinctive feature, a method of extended singular value decomposition analysis was

Tropical Pacific Decadal Variability and Its Relation to Decadal Modulations of ENSO

A 1000-yr integration of a coupled ocean-atmosphere model (ECHO-G) has been analyzed to describe decadal to multidecadal variability in equatorial Pacific sea surface temperature (SST) and
