After passing the course the students should be able to:
describe the atmospheric boundary layer, both over land and sea
apply the equations of motions on the atmospheric boundary layer
understand and quantify transport of momentum, heat and moisture to the atmosphere
describe how measurements in the boundary and surface layer are conducted
in a physically relevant way analyse measurements from the surface layer
describe processes at the mesoscale that are connected to the boundary layer, stratification and terrain
The atmospheric boundary layer. The surface layer. The Ekman layer. Basic turbulence theory. K-theory. Monin-Obukhov theory. Free convection. Resistance. Internal boundary layer. The logarithmic wind law. Measurements from the boundary and surface layer, profile and turbulence measurements. Bowen ratio. Spectral analysis. Heat flux, latent heat flux and momentum flux. Low level jet. Thermal circulations e.g. sea breeze. The influence the terrain on the wind field. Deep convection. Internal boundary layers. Waves in the atmosphere caused by the terrain and wind shear.
In the first part (boundary layer meteorology and turbulence) the teaching is given using the case method, mixing cases with lectures. In the second part (processes at the mesoscale connected to the boundary layer) the teaching is given using lectures and practical assignment with written and oral presentations.
Written examination (boundary-layer meteorology and turbulence, 10 ECTS) and home assignment (mesoscale meteorology, 4 ECTS). To pass requires approves practical assignment with homeassignment and presentation ( 1 ECTS).
