Abstract
A three-dimensional, nonhydrostatic, terrain-following numerical model was used to investigate the Adelaide Gully Wind of South Australia, a nd it reproduced well this severe downslope wind. Simulational results showed that onset and strength of the Adelaide Gully Wind is critical ly dependent on the upstream wind and potential temperature profiles, and the appearance of this local wind is also strongly influenced by t he complicated three-dimensional effect of the real topography. Sensit ivity study of the numerical model showed that a horizontal grid size of 1 km is required to resolve the fine structure of the Adelaide Gull y Wind.
