701-1221-00L | Dynamics of Large-Scale Atmospheric Flow | W | 4 credits | 2V + 1U | H. Wernli, L. Papritz | |
Abstract | This lecture course is about the fundamental aspects of the dynamics of extratropical weather systems (quasi-geostropic dynamics, potential vorticity, Rossby waves, baroclinic instability). The fundamental concepts are formally introduced, quantitatively applied and illustrated with examples from the real atmosphere. Exercises (quantitative and qualitative) form an essential part of the course. | |||||
Learning objective | Understanding the dynamics of large-scale atmospheric flow | |||||
Content | Dynamical Meteorology is concerned with the dynamical processes of the earth's atmosphere. The fundamental equations of motion in the atmosphere will be discussed along with the dynamics and interactions of synoptic system - i.e. the low and high pressure systems that determine our weather. The motion of such systems can be understood in terms of quasi-geostrophic theory. The lecture course provides a derivation of the mathematical basis along with some interpretations and applications of the concept. | |||||

651-4057-00L | Climate History and Palaeoclimatology | W | 3 credits | 2G | H. Stoll, I. Hernández Almeida, L. M. Mejía Ramírez | |
Abstract | 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. | |||||
Learning objective | 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. | |||||
Content | 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 credits | 2G | C. Schär, J. Rajczak, S. C. Scherrer | |
