Understanding of processes leading to the formation of fronts and convective storms, and basic knowledge on ocean evaporation and the physics of stable water isotopes. | |||||
701-1216-00L | Numerical Modelling of Weather and Climate | W | 4 KP | 3G | C. Schär, U. Lohmann | |
Kurzbeschreibung | The guiding principle of this lecture is that students can understand how weather and climate models are formulated from the governing physical principles and how they are used for climate and weather prediction purposes. | |||||
Lernziel | The guiding principle of this lecture is that students can understand how weather and climate models are formulated from the governing physical principles and how they are used for climate and weather prediction purposes. | |||||
Inhalt | The 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. | |||||

701-1228-00L | Cloud Dynamics: Hurricanes | W | 4 KP | 3G | U. Lohmann | |
Kurzbeschreibung | Hurricanes are among the most destructive elements in Atmospheric science. This lecture will discuss the requirements for their formation, longevity, damage potential and their relationship to global warming. It also distinguishes hurricanes from thunderstorms and tornadoes. | |||||
Lernziel | At the end of this course students will be able to distinguish tropical cyclones from extratropical thunderstorms and cyclones, project how tropical cyclones change in a warmer climate based on their physics and evaluate different tropical cyclone modification ideas. | |||||

651-2124-00L | Atmospheric General Circulation Dynamics | W | 4 KP | 2V + 1U | T. Schneider | |
Kurzbeschreibung | Understanding the fluid dynamics of the general circulation of the atmosphere is fundamental for understanding how climate is maintained and how it may vary. This course provides an intensive introduction to the principles governing the atmospheric general circulation, reaching from classical models to currently unsolved problems. | |||||
Lernziel | Understanding of the global-scale fluid dynamics of planetary atmospheres. | |||||
Inhalt | Introduction to the global-scale fluid dynamics of the atmosphere, beginning with an analysis of classical models of instabilities in atmospheric flows and leading to currently unsolved problems. Topics include Rossby waves and barotropic instability; the quasigeostrophic two-layer model and baroclinic instability; conservation laws for wave quantities and wave-mean flow interaction theory; turbulent fluxes of heat and momentum; geostrophic turbulence; genesis of zonal jets. The course focuses on Earth's atmosphere but treats the circulation of Earth's atmosphere as part of a continuum of possible planetary circulations. | |||||
