Abstract

The climate is a perfect example of a non-equilibrium system which keeps a steady state by suitably regulating the fluxes of entropy and energy with the surrounding environment. The differential radiation fuels the global circulation of the atmosphere and of the ocean, which in turn contributes to reducing the temperature gradients across the globe and in generating entropy through a variety of processes. In this seminar we will present a comprehensive theory of the thermodynamics of our planet able to treat comprehensively the Lorenz energy cycle as well as the generation of entropy through irreversible processes and we will argue that such theory allows for introducing robust, fundamental observables of the climate system and can be used for studying more general planetary atmospheres.
