Abstract Extreme El Niño events have outsized impacts and strongly contribute to the Southern Oscillation (ENSO) warm/cold phase asymmetries. There is currently no consensus on respective importance of oceanic atmospheric nonlinearities for those Here, we use general circulation models that reproduce ENSO asymmetries well quantify contribution. The linear nonlinear components wind stress response Sea Surface Temperature (SST) anomalies are isolated using ensemble experiments, used force...
Over the past two decades, significant attention has been given to ENSO (El Niño Southern Oscillation) diversity, categorizing El events as either central Pacific (CP) or eastern (EP) based on their dynamics, sea surface temperature (SST) and rainfall patterns, global teleconnections. EP include both moderate rare extreme events, such those that peaked in December 1972, 1982, 1997, 2015. Here, we will demonstrate CP are not clearly distinguishable terms of SST, pattern,...
Abstract The recharge oscillator (RO) is a simple mathematical model of the El Niño Southern Oscillation (ENSO). In its original form, it based on two ordinary differential equations that describe evolution equatorial Pacific sea surface temperature and oceanic heat content. These make use physical principles operate in nature: (a) air‐sea interaction loop known as Bjerknes feedback, (b) delayed feedback arising from slow response to winds within band, (c) state‐dependent stochastic forcing...
Abstract Extreme El Niño events have outsized global impacts and control the Southern Oscillation (ENSO) warm/cold phases asymmetries. Yet, a consensus regarding relative contributions of atmospheric oceanic nonlinearities to their genesis remains elusive. Here, we isolate contribution by conducting paired experiments forced with opposite wind stress anomalies in an general circulation model, which realistically simulates extreme thought contribute ENSO skewness (Tropical Instability Waves...
