Massive evaluation and analysis of Poincaré recurrences
Disciplines :

Collected date : from 2018 ongoing
We present a novel numerical method aimed to characterize global behaviour, in particular chaotic diffusion, in dynamical systems. It is based on an analysis of the Poincaré recurrence statistics on massive grids of initial data or values of parameters. We concentrate on Hamiltonian systems, ...

CHIMERE is a chemistry-transport model recently implemented in our laboratory. CHIMERE is able to model all kind of gaseous and aerosol species, the version used here being specifically adapted to simulate the emissions, transport and deposition of desert dust. We used two nested domains, namely ...
