Sand or fine particles, when blown by the wind, will form ridges, called sand dunes.
The wind on their upwind face is subject to a slightly higher wind velocity - caused by the dune's obstruction itself. This upwind slope will have a rounded shape. Beyond the crest, the sand will drop out thus creating a hollow curved shape.
