Main Purpose of This Lecture
•As an introduction to the effects of stratification, the case of two superposed shallow
layers, each of uniform
density, is considered.
•In reality, both the atmosphere and ocean are continuously stratified.
•This serves to introduce the concepts of barotropic and baroclinic modes.
•This also serves to introduce two widely used approximations: the rigid lid approximation and the Boussinesq approximation.
