V Lucarini, MD Chekroun - Nature Reviews Physics, 2023 - nature.com
Klaus Hasselmann's revolutionary intuition in climate science was to use the stochasticity
associated with fast weather processes to probe the slow dynamics of the climate system …

New trends in ensemble forecast strategy: uncertainty quantification for coarse-grid computational fluid dynamics

V Resseguier, L Li, G Jouan, P Dérian, E Mémin… - … Methods in Engineering, 2021 - Springer
Numerical simulations of industrial and geophysical fluid flows cannot usually solve the
exact Navier–Stokes equations. Accordingly, they encompass strong local errors. For some …

Second order perturbation theory of two-scale systems in fluid dynamics

A Debussche, U Pappalettera - Journal of the European Mathematical …, 2024 - ems.press
In the present paper we study fast-slow systems of coupled equations from fluid dynamics,
where the fast component is perturbed by additive noise. We prove that, under a suitable …

Solution properties of a 3D stochastic Euler fluid equation

D Crisan, F Flandoli, DD Holm - Journal of Nonlinear Science, 2019 - Springer

Global existence and non-uniqueness of 3D Euler equations perturbed by transport noise

M Hofmanová, T Lange, U Pappalettera - Probability Theory and Related …, 2024 - Springer
We construct Hölder continuous, global-in-time probabilistically strong solutions to 3D Euler
equations perturbed by Stratonovich transport noise. Kinetic energy of the solutions can be …

A particle filter for stochastic advection by Lie transport: a case study for the damped and forced incompressible two-dimensional Euler equation

C Cotter, D Crisan, DD Holm, W Pan… - SIAM/ASA Journal on …, 2020 - SIAM
In this work, we combine a stochastic model reduction with a particle filter augmented with
tempering and jittering, and apply the combined algorithm to a damped and forced …

Semi-martingale driven variational principles
