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…
Deviations from Gaussianity in deterministic discrete time dynamical systems
Jeroen Wouters
In this paper we examine the deviations from Gaussianity for two types of random variable converging to a normal distribution, namely sums of random variables generated by a determ…
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…
Computation of extreme heat waves in climate models using a large deviation algorithm
Francesco Ragone, Jeroen Wouters, Freddy Bouchet
Studying extreme events and how they evolve in a changing climate is one of the most important current scientific challenges. Starting from complex climate models, a key difficulty…
Edgeworth expansions for slow-fast systems with finite time scale separation
Jeroen Wouters, Georg A. Gottwald
We derive Edgeworth expansions that describe corrections to the Gaussian limiting behaviour of slow-fast systems. The Edgeworth expansion is achieved using a semi-group formalism f…
