Original Abstract

The paper focuses on determination of the wind threshold velocity of re-suspension (at the height of 10 m) and the near-ground air threshold velocity of re-suspension (at the height of 0.25 m) for particles of size 10 micrometers in a particular urban street canyon with two-way traffic. The wind threshold velocity of re-suspension is derived from a long-term measurement carried out in the city of Brno. A numerical modelling based on the finite volume method is used for a detail study of the relation between a wind velocity above buildings roofs and a near-ground air velocity in the street canyon.
