Perfect Model Predictability in a Simple Model of the Atmosphere

In the past two years the speaker has developed a new theoretical framework for analysing the predictability of dynamical systems using information theoretical concepts. These ideas have been applied to a wide variety of systems relevant to climate and atmospheric dynamics and some new perspectives on the nature of practical predictability have been unearthed. In this talk we review the theoretical concepts and apply them to a model of (baroclinic) quasi-geostrophic turbulence on a mid-latitude beta plane.
