NFYK14015U Microscale meteorology
The course will in a systematic way introduce the student to the physics of the lowest part of the atmosphere, the atmospheric boundary layer. The flow is turbulent and hence turbulent theory will occupy a large fraction of the course.
Keywords include: mean equations (ensemble, time and space), turbulent fluxes, eddy viscosity, RANS vs LES, surface energy balance, buoyancy, Monin-Obukhov similarity theory, convective boundary layers, stable boundary layers, spectra, entrainment.
Skills:
When the course is finished the student is able to:
- Describe the key properties of turbulence
- Explain the concept of Reynolds stresses, fluxes and eddy viscosity.
- Derive the governing equations for the atmospheric flow in the Atmospheric boundary layer
- Characterize the impact of thermal stratification and upon the atmospheric boundary layer.
- Explain the Buckinham Pi theorem and give examples of its usage in the surface layer.
- List the key physical properties in convective boundary layers.
- List the key physical properties in stable boundary layers.
Knowledge:
- The student will have a general understanding of the structure of the atmospheric boundary layer, with the associated structures of turbulence.
Competences:
- The student will be able to link he theoretical framework to more applied topics within wind energy and environmental studies etc.
