701-1221-00L	Dynamics of Large-Scale Atmospheric Flow	W	4 KP	2V + 1U	H. Wernli, L. Papritz
Kurzbeschreibung	Die Vorlesung vermittelt die Grundlagen der Dynamik von aussertropischen Wettersystemen (quasi-geostrophische Dynamik, potentielle Vorticity, Rossby-Wellen, barokline Instabilität). Grundlegende Konzepte werden formal eingeführt, quantitativ angewendet und mit realen Beispielen illustriert und vertieft. Übungen (quantitativ und qualitativ) sind ein wesentlicher Bestandteil des Kurses.
Lernziel	Verständnis für dynamische Prozesse in der Atmosphäre sowie deren mathematisch-physikalische Formulierung.
Inhalt	Die Atmosphärenphysik II behandelt vor allem die dynamischen Prozesse in der Erdatmosphäre. Diskutiert werden die Bewegungsgesetze der Atmosphäre und die Dynamik und Wechselwirkungen von synoptischen Systemen - also den wetterbestimmenden Hoch- und Tiefdruckgebieten. Mathematische Grundlage hierfuer ist insbesondere die Theorie der quasi-geostrophischen Bewegung, die im Rahmen der Vorlesung hergeleitet und interpretiert wird.

651-4057-00L	Climate History and Palaeoclimatology	W	3 KP	2G	H. Stoll, I. Hernández Almeida, L. M. Mejía Ramírez
Kurzbeschreibung	Climate history and paleoclimatology explores how the major features of the earth's climate system have varied in the past, and the driving forces and feedbacks for these changes. The major topics include the earth's CO2 concentration and mean temperature, the size and stability of ice sheets and sea level, the amount and distribution of precipitation, and the ocean heat transport.
Lernziel	The student will be able to describe the factors that regulate the earth's mean temperature and the distribution of different climates over the earth. Students will be able to use and understand the construction of simple quantitative models of the Earth's carbon cycle and temperature in Excel, to solve problems from the long term balancing of sinks and sources of carbon, to the Anthropogenic carbon cycle changes of the Anthropocene. Students will be able to interpret evidence of past climate changes from the main climate indicators or proxies recovered in geological records. Students will be able to use data from climate proxies to test if a given hypothesized mechanism for the climate change is supported or refuted. Students will be able to compare the magnitudes and rates of past changes in the carbon cycle, ice sheets, hydrological cycle, and ocean circulation, with predictions for climate changes over the next century to millennia.
Inhalt	1. Overview of elements of the climate system and earth energy balance 2. The Carbon cycle - long and short term regulation and feedbacks of atmospheric CO2. What regulates atmospheric CO2 over long tectonic timescales of millions to tens of millions of years? What are the drivers and feedbacks of transient perturbations like at the latest Palocene? What drives CO2 variations over glacial cycles and what drives it in the Anthropocene? 3. Ice sheets and sea level - What do expansionist glaciers want? What is the natural range of variation in the earth's ice sheets and the consequent effect on sea level? How do cyclic variations in the earth's orbit affect the size of ice sheets under modern climate and under past warmer climates? What conditions the mean size and stability or fragility of the large polar ice caps and is their evidence that they have dynamic behavior? What rates and magnitudes of sea level change have accompanied past ice sheet variations? When is the most recent time of sea level higher than modern, and by how much? What lessons do these have for the future? 4. Atmospheric circulation and variations in the earth's hydrological cycle - How variable are the earth's precipitation regimes? How large are the orbital scale variations in global monsoon systems? Will mean climate change El Nino frequency and intensity? What factors drive change in mid and high-latitude precipitation systems? Is there evidence that changes in water availability have played a role in the rise, demise, or dispersion of past civilizations? 5. The Ocean heat transport - How stable or fragile is the ocean heat conveyor, past and present? When did modern deepwater circulation develop? Will Greenland melting and shifts in precipitation bands, cause the North Atlantic Overturning Circulation to collapse? When and why has this happened before?
701-1257-00L	European Climate Change	W	3 KP	2G	C. Schär, J. Rajczak, S. C. Scherrer
Kurzbeschreibung	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.
Lernziel	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.
Inhalt	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
Skript	Slides and lecture notes will be made available at http://www.iac.ethz.ch/edu/courses/master/electives/european-climate-change.html
Voraussetzungen / Besonderes	Participants should have a background in natural sciences, and have attended introductory lectures in atmospheric sciences or meteorology.
