RISInitial Conditions for Optimal Growth in a Coupled Ocean–Atmosphere Model of ENSO
Publisher: American Meteorological Society
Abstract: Several studies have examined the conditions in the equatorial Pacific basin that lead to the maximum growth over a fixed time period, τ. These studies have the purpose of finding the characteristic precursor to an ENSO ...
A Linear Stochastic Dynamical Model of ENSO. Part I: Model Development
Publisher: American Meteorological Society
Abstract: Singular vector analysis and Floquet analysis are carried out on a linearized variant of the Zebiak?Cane atmosphere?ocean model of El Niño?Southern Oscillation (ENSO), hereinafter called the nominal model. The Floquet ...
A Linear Stochastic Dynamical Model of ENSO. Part II: Analysis
Publisher: American Meteorological Society
Abstract: In this study the behavior of a linear, intermediate model of ENSO is examined under stochastic forcing. The model was developed in a companion paper (Part I) and is derived from the Zebiak?Cane ENSO model. Four variants ...
