The physics of climate variability and climate change

M Ghil, V Lucarini - Reviews of Modern Physics, 2020 - APS
The climate is a forced, dissipative, nonlinear, complex, and heterogeneous system that is
out of thermodynamic equilibrium. The system exhibits natural variability on many scales of …

[图书][B] Random Ordinary Differential Equations

X Han, PE Kloeden, X Han, PE Kloeden - 2017 - Springer
Existence and uniqueness theorems are given for RODEs under classical and Carathéodory

Orbital insolation variations, intrinsic climate variability, and Quaternary glaciations

K Riechers, T Mitsui, N Boers… - Climate of the Past …, 2021 - cp.copernicus.org
The relative role of external forcing and of intrinsic variability is a key question of climate
variability in general and of our planet's paleoclimatic past in particular. Over the last 100 …

Asymptotic stability of evolution systems of probability measures for nonautonomous stochastic systems: Theoretical results and applications

R Wang, T Caraballo, N Tuan - Proceedings of the American Mathematical …, 2023 - ams.org
The limiting stability of invariant probability measures of time homogeneous transition
semigroups for autonomous stochastic systems has been extensively discussed in the …

[HTML][HTML] Dynamical systems, algebraic topology and the climate sciences

M Ghil, D Sciamarella - Nonlinear Processes in Geophysics, 2023 - npg.copernicus.org
The definition of climate itself cannot be given without a proper understanding of the key
ideas of long-term behavior of a system, as provided by dynamical systems theory. Hence, it …

A way to model stochastic perturbations in population dynamics models with bounded realizations

T Caraballo, R Colucci, J López-De-La-Cruz… - … in Nonlinear Science …, 2019 - Elsevier
In this paper, we analyze the use of the Ornstein–Uhlenbeck process to model dynamical
systems subjected to bounded noisy perturbations. In order to discuss the main …

On the exponential stability of stochastic perturbed singular systems in mean square

The approach of Lyapunov functions is one of the most efficient ones for the investigation of
the stability of stochastic systems, in particular, of singular stochastic systems. The main …

Transasymptotics and hydrodynamization of the Fokker-Planck equation for gluons

A Behtash, S Kamata, M Martinez, T Schäfer, V Skokov - Physical Review D, 2021 - APS
