NFYK14008U Abyssal flows
Aim: The purpose of this course is that the
student obtains a basic understanding of the various theories of
the abyssal flow how they relate to the observed large scale
Content: This course gives an introduction to the basic theories to explain the deep circulation: Stommel's mixing model, Kawase's wave model and Toggweiler's Southern Ocean model. The focus will be on the manipulation of the equations of motions to derive the fundamental properties of the different waves. Observations and numerical models will then be used to fill the theory with life.
When the course is finished it is expected that the student is able to:
- explain 3 different theories about the deep ocean circulation
- understand the spin-up of the deep circulation
The course introduces the student to the equations of motion for a continuous medium. The student will learn how to use scaling analysis to reduce the complexity of partial differential equations. Finally the student will combine the resulting equations with observations and numerical model results to relate the different forcing mechanisms to the deep flows in the ocean.
This course will provide the students with a strong background for further studies within physical oceanography, but also meteorology.
The close connection of theory to the numerical modelling of geophysical flow and the analysis of observations will ensure that the student is enabled to think laterally, translating theory into code and verifying the results with observations. This is a core competency in all geophysical subdisciplines.
