Turbulent flow on mountain topography has been investigated experimentally. Special emphasis has been placed on the flow characteristics near a large-scale embankment that is often necessitated in the construction of large facilities like aircraft landing strips in hilly areas, that are typical of large-scale development in Japan. Experiments using scale model of real topography and idealized escarpment model were conducted. It is found that the wind blowing towards the slope is accelerated, but the turbulence does not grow due to the speed-up.The quantitative effects depend on the scale of turbulence in the oncoming atmospheric boundary layer and supporting experiments were also conducted to examine the scale effects.
