In this paper, the wind ripple phenomenon; specifically, its generation, growth, disappearance, and ripple pattern, are described by reference to two parameters for a small-scale region consisting of 200×200 cells, in consideration of only the saltation and surface creep of sand. The first parameter is a coefficient allocated in a region measuring 3×3 cells, and its influence on a wind ripple pattern is clarified. The second parameter incorporates shear stress, the volume that sand jumps, the volume that sand rolls, and processing frequency. The influence of these parameters on the generation, growth, and disappearance of wind ripple is clarified.
