If you have a question about this talk, please contact Doris Allen.

I will review some of the recent developments in the theoretical and mathematical aspects of the non-equilibrium statistical mechanics of climate dynamics. At the intersection between statistical mechanics, turbulence, and geophysical fluid dynamics, this field is a wonderful new playground for applied mathematics involving large deviation theory, stochastic partial differential equations, and diffusion Monte-Carlo algorithms. We will discuss two classes of applications. First extreme heat waves as an example of a rare events with a huge impacts. Second rare trajectories that suddenly drive the complex dynamical system from one attractor to a completely different one, related to abrupt climate changes.
