Über dieses Buch

This book develops a fundamental understanding of geophysical fluid dynamics based on a mathematical description of the flows of inhomogeneous fluids. It covers these topics:

1. development of the equations of motion for an inhomogeneous fluid

2. review of thermodynamics

3. thermodynamic and kinetic energy equations

4. equations of state for the atmosphere and the ocean, salt, and moisture effects

5. concepts of potential temperature and potential density

6. Boussinesq and quasi-geostrophic approximations

7. conservation equations for vorticity, mechanical and thermal energy instability theories, internal waves, mixing, convection, double-diffusion, stratified turbulence, fronts, intrusions, gravity currents

Graduate students will be able to learn and apply the basic theory of geophysical fluid dynamics of inhomogeneous fluids on a rotating earth, including:

1. derivation of the governing equations for a stratified fluid starting from basic principles of physics

2. review of thermodynamics, equations of state, isothermal, adiabatic, isentropic changes

3. scaling of the equations, Boussinesq approximation, applied to the ocean and the atmosphere

4. examples of stratified flows at geophysical scales, steady and unsteady motions, inertia-gravity internal waves, quasi-geostrophic theory

5. vorticity and energy conservation in stratified fluids

6.boundary layer convection in stratified containers and basins

Chapter 1. Hydro-Thermo-Dynamics of Stratified Fluids
Abstract
Continuity and momentum equations were developed in the first volume GFD-I.
Emin Özsoy
Chapter 2. Basic State and Scales
Abstract
Continuity and momentum equations (1.​1), (1.​2) applied to inhomogenous fluids were introduced in Chapter
Emin Özsoy
Chapter 3. Quasi-geostrophic Theory
Abstract
Based on developments in Chap. 2, it is possible to arrive at sets of governing equations unifying GFD theory for the atmosphere and ocean, by appropriately defining the state variable s for each of these fluid domains.
Emin Özsoy
Chapter 4. Internal Waves
Abstract
Having developed basic theory of stratified geophysical flows in Chap. 1, perturbations around basic states of the atmosphere and ocean have been considered in Chap. 2. Quasi-geostrophic equations of motion have been developed and applied to the ocean and atmosphere in Chap. 3.

Chapter 5. Boundary Layers in Stratified Fluids
Abstract
Introductory theory of fluid dynamics applied to homogeneous density fluids reviewed in GFD-I have been extended to stratified ones in the present volume.
Emin Özsoy
Chapter 6. Jets and Plumes
Abstract
We present a much idealized theory of jets and plumes in this chapter. Jet flows are very similar to boundary layers considered in the last chapter. Free jets and wakes can be created away from solid boundaries by a momentum source, while buoyant plumes involve effects of density.
Emin Özsoy
Chapter 7. Exercises
Abstract
This reading exercise aims to investigate if adiabatic (or isentropic) conditions exist in the deepest parts of the earth’s ocean, based on the assumption that external factors such as motion and diffusion processes have little influence on deep water properties. It is not really a well established fact if isentropic conditions can ever exist in the deep ocean, although we expect them to be rare occurrences in nature, for entropy is not necessarily conserved in equilibrium thermodynamics.
