Heterogeneity of the Attractor of the Lorenz '96 Model: Lyapunov Analysis, Unstable Periodic Orbits, and Shadowing Properties
Chiara Cecilia Maiocchi, Valerio Lucarini, Andrey Gritsun +1
The predictability of weather and climate is strongly state-dependent: special and extremely relevant atmospheric states like blockings are associated with anomalous instability. I…
Decomposing the Dynamics of the Lorenz 1963 model using Unstable Periodic Orbits: Averages, Transitions, and Quasi-Invariant Sets
Chiara Cecilia Maiocchi, Valerio Lucarini, Andrey Gritsun
Unstable periodic orbits (UPOs) are a valuable tool for studying chaotic dynamical systems, as they allow one to distill their dynamical structure. We consider here the Lorenz 1963…
A New Mathematical Framework for Atmospheric Blocking Events
Valerio Lucarini, Andrey Gritsun
We use a simple yet Earth-like atmospheric model to propose a new framework for understanding the mathematics of blocking events. Analysing error growth rates along a very long mod…
Fluctuations, Response, and Resonances in a Simple Atmospheric Model
Andrey Gritsun, Valerio Lucarini
We study the response of a simple quasi-geostrophic barotropic model of the atmosphere to various classes of perturbations affecting its forcing and its dissipation using the forma…
