An observational, modeling and theoretical study of the scales, growth rates and spectral fluxes of baroclinic instability in the ocean is presented, permitting a discussion of the relation between the instability scale, the first baroclinic deformation scale (R def ) and the equilibrated, observed eddy scale. The geography of the large-scale quasi-geostrophic potential vorticity (QGPV) distribution is mapped out using a climatological atlas and attention drawn to key asymmetries between
