A Reduced-Order Coupled Oscillator Model for the Emergence of Episodic Convection
Sooman Han, Soong-Ki Kim, Bowen Fan +3
Extreme precipitation is a societal concern, and understanding tropical moist convection is increasingly important in a warming climate. Climate simulations show that, under hothou…
Detectability of Forced ENSO Changes under Global Warming: Insights from the Recharge Oscillator
Sooman Han, Jérôme Vialard, Alexey V. Fedorov +1
We use perfect-model, large-ensemble nonlinear Recharge Oscillator (RO) simulations to quantify ENSO internal variability and the detectability of forced changes in ENSO characteri…
An improved noise model for representing westerly wind bursts in the recharge oscillator model of ENSO
Georg A. Gottwald, Eli Tziperman, Alexey Fedorov
Westerly wind bursts (WWBs) have long been known to have a major impact on the development of El Niño events. In particular, they amplify these events, with stronger events associa…
Realistic ENSO Dynamics Requires a Damped Nonlinear Recharge Oscillator
Sooman Han, Alexey Fedorov, Jérôme Vialard
The dynamics of the El Niño-Southern Oscillation (ENSO) are succinctly captured by the Recharge Oscillator (RO) framework. However, to simulate ENSO realistically, careful choices…
