ABSTRACT
The goal was to describe the ground atmospheric layer flow over complex terrain during
specific temperature stratification and low wind flow using the Computational Fluid
Dynamic (CFD). The numeric simulation was run for the model area of the Horní
Lomná valley. The automatic transport of terrain from geographic information system to
CFD interface was made, the real boundary weather condition was applied and the flow
of particulate matter in the valley from various sorts of pollution sources was studied.
The simulation was compared with the Gaussian dispersion model and the pollution
measurement data.
