DISPERSION SCENARIOS OVER COMPLEX TERRAIN

A presentation of preliminary results from a real-time simulation of full-scale dispersion experiments carried out over complex terrain in Northern Spain is given. Actual wind and turbulence measurements as observed during the experiments were analysed and used as input data for a series of simulations made with a combined flow and diffusion model (LINCOM/RIMPUFF). The experiments and the obtained real-time data sets of winds and turbulence are described together with a tower-matching backfitting procedure. Preliminary results of wind fields and mean concentrations are given. The results are suitable for subsequent comparison with observed mean dispersion data when they become available.
