Developing a theory of climate requires an accurate parameterization of the heat transport induced by the cyclones and anticyclones that characterize the mid-latitude ocean and atmosphere. These weather systems are generated though baroclinic instability of the large scale flows. We will present a scaling theory that quantitatively predicts the meridional heat flux generated through baroclinic turbulence as a function of the large-scale flow characteristics. The theory is then used as a quantitative parameterization in the case of meridionally dependent forcing in the fully turbulent regime. Beyond its relevance for climate theories, our work is an intriguing example of a successful closure for a fully turbulent flow.
