Strong and moderate nonlinear El Niño regimes (2016, background): “Recent studies indicate that two types of El Niño (EN) have occurred over the last five decades, one with SST anomalies peaking in the eastern Pacific and the other peaking in the central equatorial Pacific (Larkin and Harrison 2005; Ashok et al. 2007; Kug et al. 2009).”
Warm Pool and Cold Tongue El Nino Events as Simulated by the GFDL 2.1 Coupled GCM (2010, background): “The distinctive global impacts of the two types of El Niño were reported recently in several studies (Larkin and Harrison 2005a,b; Ashok et al. 2007; Weng et al. 2007; Ashok et al. 2009).”
Analysis of the non-linearity in the pattern and time evolution of El Niño southern oscillation (2013, background): “These type of events are named El Niño Modoki by Ashok et al. (2007).”
State of the climate in 2010 (2011, neutral): “1.3b; see Ashok et al. 2007).”
The challenge of simulating the warmth of the mid-Miocene climatic optimum in CESM1 (2013, result): “The permanent El Niño imposed in some of our simulations is comparable to proxy based SST reconstructions for the equatorial Pacific (Wara et al., 2005; Dekens et al., 2008) and similar to previous studies which have prescribed this type of SST distribution (Shukla et al., 2009; Vizcaíno et al., 201”
Biological response to the 1997–98 and 2009–10 El Niño events in the equatorial Pacific Ocean (2012, background): “…warming in the central equatorial Pacific (CEP) otherwise known as the central Pacific (CP)-El Niño, warm-pool El Niño, dateline El Niño, or El Niño Modoki [Latif et al., 1997; Larkin and Harrison, 2005; Yu and Kao, 2007; Ashok et al., 2007; Kao and Yu, 2009; Kug et al., 2009; Yu and Kim, 2010].”
Reconstructing sea level using cyclostationary empirical orthogonal functions (2011, methodology): “The third CSEOFmode in Figure 4 appears to capture the ENSO Modoki signal [Ashok et al., 2007], judging by the spatial pattern of the LVs and also because this mode has a correlation of 0.55 with an El Niño Modoki SST index from 1950 to 2010.”
Ranking the strongest ENSO events while incorporating SST uncertainty (2016, neutral): “For example, during the 2000s, a number of El Niño events had their maximum SSTAs in the western or central Paci ﬁ c, the so-called “ Modoki ” or “ Central Paci ﬁ c ” El Niño event [e.g., Ashok et al ., 2007; Yu and Kim , 2010; Hu et al ., 2012].”
The unique 2009–2010 El Niño event: A fast phase transition of warm pool El Niño to La Niña (2011, background): “[2] In recent decades El Niño‐Southern Oscillation (ENSO) seems to have undergone a regime shift that a new type of El Niño whose anomaly is confined to the central Pacific is occurring more frequently [Ashok et al., 2007; Kao and Yu, 2009; Kug et al., 2009; Larkin and Harrison, 2005].”
Identifying the types of major El Niño events since 1870 (2013, methodology): “…those obtained by other three identification methods: the central-location method (i.e. the NINO method hereafter) used in Kug et al. (2009) and Yeh et al. (2009), the EMI method used in Ashok et al. (2007), and the CT and WP index method (CT/WP method hereafter) proposed by Ren and Jin (2011).”
Sugarcane Under Pressure: An Overview of Biochemical and Physiological Studies of Abiotic Stress (2011, background): “Additionally, an increase in the frequency of a different kind of El Nino, which is characterized by an anomalous increase in sea surface temperature (SST) in the central tropical pacific, flanked by colder regions in the west and east (Yeh et al.2009), may alter the precipitation distribution patte”
Signals of El Niño Modoki in the tropical tropopause layer and stratosphere (2012, methodology): “Furthermore, the OLR anomalies show a tripolar form as SSTA during El Niño Modoki events, with patterns that correspond to patterns of rainfall anomalies, as noted by Ashok et al. (2007) and Weng et al. (2009).”
The Teleconnection of El Niño Southern Oscillation to the Stratosphere (2019, methodology): “…for Central Pacific (CP) El Niño events, SST anomalies peak in the central equatorial Pacific, also called dateline or Modoki El Niño events (Ashok et al., 2007; Larkin & Harrison, 2005; middle panel of Figure 3), while for East Pacific (EP or canonical) El Niño events, SST anomalies peak…”
A change in the relationship between tropical central Pacific SST variability and the extratropical atmosphere around 1990 (2012, background): “Date Line El Niño (Larkin and Harrison 2005), El Niño Modoki (Ashok et al 2007) or warm pool El Niño (Kug et al 2009), while the conventional ENSO (e.g., Rasmusson and Carpenter 1982) is referred to as the Eastern Pacific (EP) type.”
Improved ensemble-mean forecasting of ENSO events by a zero-mean stochastic error model of an intermediate coupled model (2016, result): “In contrast to the 1st mode, the 2nd EOF mode appears to capture the evolution of El Niño Modoki (e.g., Ashok et al. 2007).”
