KurzbeschreibungMesoscale meteorology focusing on processes relevant for the evolution of precipitation systems. Discussion of empirical and mathematical-physical models for, e.g., fronts and convective storms. Consideration of oceanic evaporation, transport and the associated physics of stable water isotopes. Introduction to weather radar being the widespread instrument for observing mesoscale precipitation.
LernzielBasic concepts of observational and theoretical mesoscale meteorology, including precipitation measurements and radar. Knowledge about the interpretation of radar images. 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.
701-1216-00LNumerical Modelling of Weather and Climate Information W4 KP3GC. Schär, U. Lohmann
KurzbeschreibungThe 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.
LernzielThe 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.
InhaltThe 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.

701-1226-00LInter-Annual Phenomena and Their PredictionW2 KP2GC. Appenzeller
KurzbeschreibungThis course provides an overview of the current ability to understand and predict short-term climate variability in the tropical and extra-tropical region and provides insights on how operational weather and climate services are organized.
LernzielStudents will acquire an understanding of the key atmosphere and ocean processes involved, will gain experience in analyzing and predicting short-term climate variability and learn how operational weather and climate services are organised and how scientific developments can improve these services.
InhaltThe course covers the following topics:

Part 1:
- a brief introduction into short-term climate variability and some basic concepts
- a brief review of climate data and the statistical concepts used for analysing climate variability (e.g. correlation analysis, teleconnection maps, EOF analysis)

Part 2:
- inter-annual variability in the tropical region (e.g. ENSO, MJO)
- inter-annual variability in the extra-tropical region (e.g. Blocking, NAO, PNA, regimes)

Part 3:
- prediction of short-term climate variability (seasonal forecasts, statistical methods, ensemble prediction systems)
- verification methods for probabilistic forecast systems

Part 4:
- challenges for operational weather and climate services
- weather and climate extremes
- early warning systems
- a visit to the forecasting centre of MeteoSwiss

701-1228-00LCloud Dynamics: Hurricanes Information W4 KP3GU. Lohmann
KurzbeschreibungHurricanes 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.
LernzielAt 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.

651-2124-00LAtmospheric General Circulation Dynamics Information W4 KP2V + 1UT. Schneider
KurzbeschreibungUnderstanding 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.
LernzielUnderstanding of the global-scale fluid dynamics of planetary atmospheres.
InhaltIntroduction 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.
