Literature:
John M. Wallace, Peter V. Hobbs, Atmospheric Science, Academic Press, 2006 One of the best introductory books on atmospheric physics! All areas are described very clearly and comprehensibly and examples are also explicitly calculated. There is also a website with lots of additional information for students, assignments, graphics, etc., unfortunately not cheap.

Comment:
The seminar is a literature seminar, which is also referred to as the "Journal Club" at other universities and occurs in many variations. The objectives of this seminar are to keep the participants up to date on research, to facilitate the implementation of findings in research everyday life and to promote the ability of critical reading. There is a tremendous (still increasing) amount of literature, and this extensive offer calls for a high level of competence and effective techniques for critically handling this information. The versatility of the seminar and the broad spectrum of treated Magazines relevant to atmospheric research bring a considerable wealth of experience and knowledge to both students and members of the working group.

Content
In this lecture we will deal with the topic of atmospheric modelling. We will start with an overview about different types of atmospheric models, followed by a short course on the basic structure of the atmosphere and the governing equations for atmospheric dynamics and transport. As an example for conceptual mathematical models we will first consider lower dimensional models of the stratospheric Brewer-Dobson circulation (e.g., two-dimensional transformed Eulerian Mean). Thereafter, we will discuss different modelling techniques (e.g., Eulerian and Lagrangian modelling frameworks) and different numerical approaches used in atmospheric models. Here, we will consider finite difference, finite volume, spectral and finite element methods and different model grids and vertical coordinate systems used in atmospheric models. A short outline is:
- Introduction: Types of "models''
- Atmospheric structure and model equations for transport and dynamics
- Conceptual lower-dimensional mathematical models (example: stratospheric
Brewer-Dobson circulation)
- Numerical models
- Numerical approaches for atmospheric models
- Numerical methods for advection
- Statistical modelling and data analysis methods
Recommended requirement
"Introduction to Atmospheric Physics". In addition "Atmospheric Dynamics" would be very helpful.
