Description
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.
