401-5930-00LSeminar in Physics of the Atmosphere for CSE4 credits2SH. Joos, C. Schär
AbstractIn this seminar, the process of writing a scientific proposal is
introduced. The essential elements of a proposal, including the peer
review process, are outlined and class exercises train
scientific writing skills. Knowledge exchange between class
participants is promoted through the preparation of a master thesis
proposal and evaluation of each other's work.
ObjectiveScientific writing skills
How to effectively write a scientific proposal
ContentIn this seminar, the process of writing a scientific proposal will be
introduced. The essential elements of a proposal, including the peer
review process, will be outlined and class exercises will train
scientific writing skills. Knowledge exchange between class
participants is promoted through the preparation of a master thesis
proposal and evaluation of each other's work.
Prerequisites / NoticeIn this seminar it is mandatory to write a proposal about an upcoming MSc thesis or semester project. If no such project is planned, this Seminar cannot be taken. Please contact the lecturers on time if you plan to take this seminar.

3 credits6RC. Schär
AbstractThis lecture conveys the mathematical basis necessary for the development and application of numerical models in the field of Environmental Science. The lecture material includes an introduction into numerical techniques for solving ordinary and partial differential equations, as well as exercises aimed at the realization of simple models using the computer language Python.
ObjectiveAbility to develop simple numerical schemes and to implement these schemes using the programming language Python. Ability to critically use more complex numerical models.
ContentClassification of numerical problems, introduction to finite-difference methods, linear and nonlinear tranport equation, time integration schemes, non-linearity, conservative numerical techniques, overview of other methods. Examples and exercises from a diverse cross-section of Environmental Science.

Three exercises, each two hours in length, are integrated into the lecture. The implementation language is Python (previous experience not necessary, a Phython introduction is provided). Example programs and graphics tools are supplied.
LiteratureList of literature is provided.
701-1216-00LWeather and Climate Models Information 4 credits3GC. Schär, D. Leutwyler, M. Wild
AbstractThe course provides an introduction to weather and climate models. It discusses how these models are built addressing both the dynamical core and the physical parameterizations, and it provides an overview of how these models are used in numerical weather prediction and climate research. As a tutorial, students conduct a term project and build a simple atmospheric model using the language PYTHON.
ObjectiveAt the end of this course, students understand how weather and climate models are formulated from the governing physical principles, and how they are used for climate and weather prediction purposes.
ContentThe course provides an introduction into the following themes: numerical methods (finite differences and spectral methods); adiabatic formulation of atmospheric models (vertical coordinates, hydrostatic approximation); parameterization of physical processes (e.g. clouds, convection, boundary layer, radiation); atmospheric data assimilation and weather prediction; predictability (chaos-theory, ensemble methods); climate models (coupled atmospheric, oceanic and biogeochemical models); climate prediction. Hands-on experience with simple models will be acquired in the tutorials.
