On Friday, December 17, 2021, at 16:00 in 48-580 there will be a talk by Evan Camrud from the Iowa State University, IA, USA. 

The title of the talk is 

"Stochastic Lorenz 96: predictions on equilibrium and convergence“.

Abstract: The Lorenz 96 system, originally introduced by Edward Lorenz in "Predictability: a problem partially solved", was constructed to model the behavior of a meteorological quantity advected by the atmosphere. It is based on a truncation of a dyadic model for the Navier-Stokes interactions. We approach a stochastically forced version of this system, with degenerate noise and dissipation, to try to understand the spread of dissipation through the system. In particular, our goal is to understand the interaction of energy conserving nonlinearities and dissipation in arbitrary energy conserving systems. Preliminary results on positive recurrence of this stochastic Lorenz 96 system will be introduced.
