Ageostrophic Motion,., that the scaling of the motion is isotropic horizontally. The low-frequency Kelvin wave is not horizontally isotropic, since its offshore scale is the deformation radius, which for low frequencies is small compared with the wavelength. In this chapter we consider some of the refinements to quasig

Preliminaries,perience has also shown that the recognition of the underlying dynamical concepts applicable to both the atmosphere and the oceans is an excellent starting point for the study of either. Geophysical fluid dynamics is the subject whose concerns are the fundamental dynamical concepts essential to an u

Fundamentals, any particular problem. However, the equations of motion are so complex that only rarely can exact solutions be found, and any method of approximation of the equations requires first an understanding of the broad, general, physical principles with which any approximation must be consistent.

Inviscid Shallow-Water Theory,oses to our consideration of this physical system. It is first of all simple enough so that the issues raised by the problem of geostrophic degeneracy can be dealt with directly without the need to simultaneously treat the complexities of the thermodynamics of a density-stratified fluid. The first g

Friction and Viscous Flow,eak, almost everywhere, when compared with the Coriolis acceleration and the pressure gradient. Friction rarely upsets the geostrophic balance to lowest order. Indeed, for many flows it is probably also true that the dissipative time scale is long compared to the advective time scale, i.e., that the

Ageostrophic Motion,ion that the time scale of the motion is large compared to ... This is not always sufficient, as the discussion of the Kelvin wave in Section 3.9 indicated. When the wavelength of the Kelvin wave is long compared to the deformation radius, the frequency is small compared to .. Yet the equation of mo
