Lecture/Reading: Monday, 14-16; Prof. Dr. Gerrit Lohmann

Tutorial: Monday, 16-17; Justus Contzen, Lars Ackermann


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.

German Version:

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.

Course and examination performance

There are two parts: Course achievements and examination achievements (Studienleistungen und Prüfungsleistungen)

Course achievements:

50% of the points of the exercise sheets are required. Furthermore, we require active participation with at least one time showing a solution in the chat room. 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.


Examination achievements:

You have to pass the oral exam on July 26. link to terminplaner

The exam is based on the exercises and the general content of the lecture. The procedure follows the rules of pep.
