Analysis of the relative importance of terrain heterogeneity, heterogeneous land use and heterogeneous forcing on the ABL structure using LES
Responsible: Matthias Sühring?
Project type: ​DFG research project with ​DWD (German Weather Service), ​Universität Bayreuth and ​Eberhard Karls Universität Tübingen
Duration: 01/11/2010-

The atmospheric boundary layer (ABL) is directly affected by the underlying surface. Inhomogeneous meteorological surface forcing can yield to circulations affecting the turbulent exchange in the entire ABL.

This research project studies the effect of heterogeneous meteorological forcing on the structure of the ABL using LES. Simulations based on the LITFASS-2003 dataset will be carried out to investigate exchange processes and the state of turbulent mixing under different atmospheric conditions. Furthermore, the measurement strategies of the LITFASS-2003 experiment will be investigated and possible improvements for the measurement strategies will be derived.
