The focus of the course is to identify the underlying dynamics for
the atmosphere-ocean system. This is done through theory, numerical
models, and statistical data analysis. It has been recognized that the
atmospheric and oceanic flow binds together the interactions between the
biosphere, hydrosphere, lithosphere and atmosphere that control the
planetary environment. The fundamental concepts of atmosphere-ocean
flow, energetics, vorticity, wave motion are described. This includes
atmospheric wave motion, extratropical synoptic scale systems, the
oceanic wind driven and thermohaline circulation. These phenomena are
described using the dynamical equations, observational and proxy data,
as well basic physical and mathematical concepts. Exercises complement
the lessons.
In den letzten Jahren wurde erkannt, dass Wechselwirkungen zwischen
Klimakomponenten wie der Atmosphäre und des Ozean für die Klimaforschung
essenziell sind. Der Schwerpunkt des Kurses liegt auf den theoretischen
Grundlagen der Dynamik im Atmosphäre-Ozean-Eissystem. Die grundlegenden
Konzepte von Strömungen, Energie, großskalige Wirbel und Wellenbewegung
werden beschrieben. Dies umfasst atmosphärische Wellenbewegungen, die
ozeanische windinduzierte Strömung und die thermohaline Zirkulation.
Anhand von Beispielen werden die grundlegenden Methoden
erlernt.

Workload /credit points: 3 CP, 90 h
• lectures and preparation: 24 h (2 h x 12 weeks)
• repeating the lectures/learning/reading: 24 h (2 h x 12 weeks)
• example classes: 9 h (1 h x 9 weeks)
• example classes homework: 27 h (3 h x 9 weeks)

There are two parts: Course achievements and examination achievements (Studienleistungen und Prüfungsleistungen)
50% of the points of the exercise sheets are required. Furthermore, we require active participation with at least one time showing a solution.
Working in study groups is encouraged, but each student is responsible for his/her own solution. If the solution is typewritten (e.g. with LaTex, Rmarkdown, or word), we allow up to 3 persons to be listed on a solution sheet. Send in your solutions in form of a PDF to our email addresses (one PDF per group!).
You have to pass the written exam Sept. 26, 10-12.
The exam is based on the exercises and the general content of the lecture. The procedure follows the rules of pep.
