| Kurzbeschreibung | In dieser Veranstaltung werden die Grundlagen der Atmosphärenphysik behandelt. Dies umfasst die Themen: Wolken- und Niederschlagsbildung insb. Vorhersage von Gewitterbildung, Aerosolphysik sowie künstliche Wetterbeeinflussung. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lernziel | Die Studierenden können - die Mechanismen der Gewitterbildung mit Wissen über Feuchteprozesse und Wolkenmikrophysik erklären. - die Bedeutung der Wolken und Aerosolpartikel für die künstliche Niederschlagsbeeinflussung evaluieren. In dem Fach "Atmosphärenphysik" werden die Kompetenzen Prozessverständnis, Systemverständnis und Datenanalyse & Interpretation gelehrt, angewandt und geprüft. Die Kompetenz Messmethoden wird ebenfalls gelehrt. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inhalt | Im ersten Teil werden ausgewählte Konzepte der für atmosphärische Prozesse wichtigen Thermodynamik eingeführt: Die Studierenden lernen das Konzept des thermodynamischen Gleichgewichts kennen und leiten ausgehend vom ersten Hauptsatz der Thermodynamik die Clausius-Clayperon Gleichung her, welche für die Behandlung von Phasenübergängen in Wolken wichtig ist. Ausserdem erlernen die Studierenden die Klassifizierung von Sonderierungen sowie den Umgang mit thermodynamischen Diagrammen (Tephigramm) und die Kennzeichnung charakteristischer Grössen (Wolkenbasis, Wolkenoberkante, freisetzbare Energie, etc.) darin. Das Konzept von atmosphärischen Mischungspozessen wird anhand der Nebelbildung eingeführt. Anhand vom "Luftpaket-Modell" wird das Konzept der Konvektion erarbeitet. Im mittleren Teil des Kurses werden Aerosolpartikel eingeführt. Neben einer Beschreibung der physikalischen Eigenschaften dieser Partikel lernen die Studierenden die Rolle von Aerosolpartikeln für die Wolkenbildung mit Hilfe der Köhler-Theorie kennen. Danach werden mikrophysikalische Prozesse inklusive der Eiskristallbildung diskutiert. Basierend auf diesen Grundlagen werden die Arten der Niederschlagsbildung eingeführt und unterschiedliche Formen von Niederschlag (konvektiv vs. stratiform) diskutiert, welche anhand der Diskussion von Stürmen und deren Entwicklungsstufen vertieft werden. Diese Konzepte werden angewendet, um verschiedene künstliche Wetterbeeinflussungs-Ideen zu verstehen und ihre Machbarkeit abzuschätzen. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 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 natural factors lead to variations in the earth's mean temperature, the growth and retreat of ice sheets, and variations in ocean and atmospheric circulation patterns, including feedback processes. 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 | The course spans 5 thematic modules: 1. Cyclic variation in the earth's orbit and the rise and demise of ice sheets. 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? How stable or fragile is the ocean heat conveyor, past and present? 2. Feedbacks on climate cycles from CO2 and methane. What drives CO2 and methane variations over glacial cycles? What are the feedbacks with ocean circulation and the terrestrial biosphere? 3. 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? 4. Century-scale droughts and civil catastrophes. 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. How sensitive is Earth's long term climate to CO2 and cloud feedbacks? What regulates atmospheric CO2 over long tectonic timescales of millions to tens of millions of years? The weekly two hour lecture periods will feature lecture on these themes interspersed with short interactive tasks to apply new knowledge. Over the semester, student teams will each present in class one debate based on two scientific articles of contrasting interpretations. With flexible scheduling, students will participate in a laboratory activity to generate a new paleoclimate record from stalagmites. Student teams will be supported by an individual tutorial meeting to assist in debate preparation and another to assist in the interpretation of the lab activity data. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Kurzbeschreibung | Watershed Modelling is a practical course on numerical water balance models for a range of catchment-scale water resource applications. The course covers GIS use in watershed analysis, models types from conceptual to physically-based, parameter calibration and model validation, and analysis of uncertainty. The course combines theory (lectures) with a series of practical tasks (exercises). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lernziel | The main aim of the course is to provide practical training with watershed models for environmental engineers. The course is built on thematic lectures (2 hrs a week) and practical exercises (2 hrs a week). Theory and concepts in the lectures are underpinned by many examples from scientific studies. A comprehensive exercise block builds on the lectures with a series of 4 practical tasks to be conducted during the semester in group work. Exercise hours during the week focus on explanation of the tasks. The course is evaluated 50% by performance in the graded exercises and 50% by a semester-end oral examination (30 mins) on watershed modelling concepts. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inhalt | The first part (A) of the course is on watershed properties analysed from DEMs, and on global sources of hydrological data for modelling applications. Here students learn about GIS applications (ArcGIS, Q-GIS) in hydrology - flow direction routines, catchment morphometry, extracting river networks, and defining hydrological response units. In the second part (B) of the course on conceptual watershed models students build their own simple bucket model (Matlab, Python), they learn about performance measures in modelling, how to calibrate the parameters and how to validate models, about methods to simulate stochastic climate to drive models, uncertainty analysis. The third part (C) of the course is focussed on physically-based model components. Here students learn about components for soil water fluxes and evapotranspiration, they practice with a fully-distributed physically-based model Topkapi-ETH, and learn about other similar models at larger scales. They apply Topkapi-ETH to an alpine catchment and study simulated discharge, snow, soil moisture and evapotranspiration spatial patterns. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Skript | There is no textbook. Learning materials consist of (a) video-recording of lectures; (b) lecture presentations; and (c) exercise task documents that allow independent work. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
