Reduced-Order Models for Coupled Dynamical Systems: Data-driven Methods and the Koopman Operator
Manuel Santos Gutiérrez, Valerio Lucarini, Mickaël D. Chekroun +1
Providing efficient and accurate parametrizations for model reduction is a key goal in many areas of science and technology. Here we present a strong link between data-driven and t…
Analysis of a bistable climate toy model with physics-based machine learning methods
Maximilian Gelbrecht, Valerio Lucarini, Niklas Boers +1
We propose a comprehensive framework able to address both the predictability of the first and of the second kind for high-dimensional chaotic models. For this purpose, we analyse t…
Predictors and Predictands of Linear Response in Spatially Extended Systems
Umberto Maria Tomasini, Valerio Lucarini
The goal of response theory, in each of its many statistical mechanical formulations, is to predict the perturbed response of a system from the knowledge of the unperturbed state a…
Dynamical Landscape and Multistability of a Climate Model
Georgios Margazoglou, Tobias Grafke, Alessandro Laio +1
We apply two independent data analysis methodologies to locate stable climate states in an intermediate complexity climate model and analyze their interplay. First, drawing from th…
Fingerprinting Heatwaves and Cold Spells and Assessing Their Response to Climate Change using Large Deviation Theory
Vera Melinda Galfi, Valerio Lucarini
Extreme events provide relevant insights into the dynamics of climate and their understanding is key for mitigating the impact of climate variability and climate change. By applyin…
Response Theory and Phase Transitions for the Thermodynamic Limit of Interacting Identical Systems
Valerio Lucarini, G. A. Pavliotis, Niccolò Zagli
We study the response to perturbations in the thermodynamic limit of a network of coupled identical agents undergoing a stochastic evolution which, in general, describes non-equili…
