701-1216-00LNumerical Modelling of Weather and ClimateW4 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.

Voraussetzungen / BesonderesPrerequisites: to follow this course, you need some basic background in numerical methods (e.g., "Numerische Methoden in der Umweltphysik", 701-0461-00L)
651-4053-03LBoundary Layer Meteorology and Air Pollution Modeling: Part IIW2 KP2GM. Rotach, J. Schmidli
KurzbeschreibungThe Planetary Boundary Layer (PBL) as the lowest atmospheric layer constitutes the interface between the atmosphere and the Earth's surface. Theory on transport processes in the PBL and their dynamics is provided. Also dispersion modeling of pollutants is discussed. Part II completes the theoretical background and focuses on non-ideal applications and extensions.
LernzielOverall goals of this course are given below. Part II focuses on non-ideal applications.
Students have basic knowledge on atmospheric turbulence and theoretical as well as practical approaches to treat Planetary Boundary Layer flows. They are familiar with the relevant processes (turbulent transport, forcing) within and typical states of the Planetary Boundary Layer. Idealized concepts are known as well as their adaptations under real surface conditions (as for example over complex topography). Different types of atmospheric dispersion models are known including their underlying assumptions, capabilities, drawbacks and advantages.
Inhalt- Conservation equations in a turbulent flow
- Closure problem and closure assumptions
- Spectral characteristics
- Concepts for non-ideal boundary layer conditions
- Eulerian and Lagrangian pollutant dispersion models
- Applications in dispersion modeling
- Examples from urban and terrain-influenced boundary layers and air pollution modeling.
