Dynamics II course 2016
Lecture: Monday, 14-16, room S3121
Prof. Dr. Gerrit Lohmann
Tutorial: Monday, 16-17, room S3121
Tutors: Sebastian Hinck and Lu Niu
starting April 4, 2016 with the lecture
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.
