Baroclinic instability of a meridionally varying basic state
… the normal modes. Some aspects of resonant triad dynamics in a meridionally uniform, vertically sheared, two-layer model are considered in chapter two. It is shown that non-linear interactions between a resonant triplet of neutral waves can lead to baroclinic instability. It is also demonstrated …

Momentum, mass, heat, and vorticity balances from oceanic measurements of current and temperature
The local dynamics of low-frequency motions in the MODE region are investigated from three arrays of moored measurements of current and temperature. Tests for lowest-order balances of horizontal momentum, mass, heat, heat and vorticity within established errors are carried out. Geostrophic …

Generation of mid-ocean eddies : the local baroclinic instability hypothesis
The plausibility of local baroclinic instability as a generation mechanism for midocean mesoscale eddies is examined with a two-layer, quasi-geostrophic (QG) model forced by an imposed, horizontally homogeneous, vertically sheared mean flow and dissipated through bottom Ekman friction, Explanations …
