A finite-volume solver (SWIFT) for numerical prediction of flow and dispersion over hills is described. Comparison of predictions with experiment are made for (i) adiabatic flow over 2-D hills (RUSHIL experiment) and (ii) stably-stratified flow over real terrain (Cinder Cone Butte). Suitably-modified k−ε turbulence models are shown to yield satisfactory wind speed profiles (windpower) and terrain-amplification factors (dispersion applications).
