Applications of large deviation theory in geophysical fluid dynamics and climate science
Vera Melinda Galfi, Valerio Lucarini, Francesco Ragone +1
The climate system is a complex, chaotic system with many degrees of freedom and variability on a vast range of temporal and spatial scales. Attaining a deeper level of understandi…
A Large Deviation Theory-based Analysis of Heat Waves and Cold Spells in a Simplified Model of the General Circulation of the Atmosphere
Vera Melinda Galfi, Valerio Lucarini, Jeroen Wouters
We study temporally persistent and spatially extended extreme events of temperature anomalies, i.e. heat waves and cold spells, using large deviation theory. To this end, we consid…
Stochastic model reduction for slow-fast systems with moderate time-scale separation
Jeroen Wouters, Georg A. Gottwald
We propose a stochastic model reduction strategy for deterministic and stochastic slow-fast systems with finite time-scale separation. The stochastic model reduction relaxes the as…
Response Formulae for -point Correlations in Statistical Mechanical Systems and Application to a Problem of Coarse Graining
Valerio Lucarini, Jeroen Wouters
Predicting the response of a system to perturbations is a key challenge in mathematical and natural sciences. Under suitable conditions on the nature of the system, of the perturba…
Parametrization of stochastic multiscale triads
Jeroen Wouters, Stamen I. Dolaptchiev, Valerio Lucarini +1
We discuss applications of a recently developed method for model reduction based on linear response theory of weakly coupled dynamical systems. We apply the weak coupling method to…
Rare event computation in deterministic chaotic systems using genealogical particle analysis
Jeroen Wouters, Freddy Bouchet
In this paper we address the use of rare event computation techniques to estimate small over-threshold probabilities of observables in determin-istic dynamical systems. We demonstr…
