Abstract
A meteorological mesoscale model is used to simulate the time dependent distribution of temperature and the corresponding development of slope-wind systems in a narrow two-dimensional valley during the course of a cloud-free day. A numerical sound particle model was designed to cope with both the uneven terrain and the inhomogeneous meteorological environment. The acoustical model takes up the simulated meteorological fields and calculates the propagation of noise which originates from a line source at one of the slopes of this valley. The coupled modeling system ensures consistency of topography, meteorological parameters and the sound field. The temporal behaviour of the sound pressure level across the valley is examined. It is only governed by the time dependent meteorology. The results show remarkable variations of the sound level during the course of a day.
