Abstract: The atmosphere, ocean, and other components of the climate system behave in a fairly irregular way. A major surprise of the late
20th century was the realization that such behavior could be produced by natural systems with a small number of degrees of freedom, governed
by fully deterministic, but nonlinear laws. Still, the climate system has a large number of degrees of freedom, and ample room for random
factors to intervene. Can we reconcile a low-order, deterministically nonlinear description of weather or climate with a high-order, possibly
linear but random one? This talk will present some steps on the road to such a "grand unification," and implications for weather and climate
predictability will be discussed.

Seguirà un dibattito informale (anche in italiano) sugli argomenti trattati nel seminario.

Tutti gli interessati sono invitati a partecipare.
