PhD Comprehensive Exam | Tianlang Luo, Stochastic Dynamics of and ENSO Model
El Niño–Southern Oscillation (ENSO) is a climate phenomenon occurring every 3-7 years in the tropical Pacific. It is a pattern shifting between anomalous warm and cold events within equatorial Pacific, with irregularity in amplitude, duration, temporal evolution, and spatial structure. This research focuses on a specific ENSO model developed by Majda and coworkers, where state-dependent stochastic wind bursts and nonlinear advection of sea surface temperature are coupled to a simple ocean–atmosphere model that is otherwise deterministic, linear, and stable.
