Sand ripples
Sand ripples - Wave like patterns created by wind and sand. The waves run perpendicular to prevailing wind direction. Distances between single ripples are proportional to wind strength while strong winds prevent ripples creation at all. On a microscale it involves a single grain of sand being blown by wind, pushing other grains on impact, and rolling down off a steep lee side of a ripple. Details of mechanism of sand ripples and dunes creation are still not well understood and it is an area of ongoing research.
