Analysis and forecast atmospheric wind velocity profiles have the important roles in research the dispersion of the pollutants and its effects to surrounding environment. A three-dimensional numerical modeling on atmospheric wind flow over a mountain under neutral condition was processed to attain the velocity contours of atmospheric wind field on complex terrains. Meteorological conditions and geographical conditions including four downwind velocities and two underlying surface roughness characteristics were considered in the present study. Water tank experiment and Particle Image Velocimetry...
