701-0461-AAL | Numerical Methods in Environmental Physics Enrolment ONLY for MSc students with a decree declaring this course unit as an additional admission requirement. Any other students (e.g. incoming exchange students, doctoral students) CANNOT enrol for this course unit. | 3 credits | 6R | C. Schär | |||||||||||||||||||||||||||||||||||

Abstract | This 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. | ||||||||||||||||||||||||||||||||||||||

Objective | Ability to develop simple numerical schemes and to implement these schemes using the programming language Python. Ability to critically use more complex numerical models. | ||||||||||||||||||||||||||||||||||||||

Content | Classification 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. | ||||||||||||||||||||||||||||||||||||||

Literature | List of literature is provided. | ||||||||||||||||||||||||||||||||||||||

701-1257-00L | European Climate Change | 3 credits | 2G | C. Schär, J. Rajczak, S. C. Scherrer | |||||||||||||||||||||||||||||||||||

Abstract | The lecture provides an overview of climate change in Europe, from a physical and atmospheric science perspective. It covers the following topics: • observational datasets, observation and detection of climate change; • underlying physical processes and feedbacks; • numerical and statistical approaches; • currently available projections. | ||||||||||||||||||||||||||||||||||||||

Objective | At the end of this course, participants should: • understand the key physical processes shaping climate change in Europe; • know about the methodologies used in climate change studies, encompassing observational, numerical, as well as statistical approaches; • be familiar with relevant observational and modeling data sets; • be able to tackle simple climate change questions using available data sets. | ||||||||||||||||||||||||||||||||||||||

Content | Contents: • global context • observational data sets, analysis of climate trends and climate variability in Europe • global and regional climate modeling • statistical downscaling • key aspects of European climate change: intensification of the water cycle, Polar and Mediterranean amplification, changes in extreme events, changes in hydrology and snow cover, topographic effects • projections of European and Alpine climate change | ||||||||||||||||||||||||||||||||||||||

Lecture notes | Slides and lecture notes will be made available at http://www.iac.ethz.ch/edu/courses/master/electives/european-climate-change.html | ||||||||||||||||||||||||||||||||||||||

Prerequisites / Notice | Participants should have a background in natural sciences, and have attended introductory lectures in atmospheric sciences or meteorology. |
