Particles are rounded, since rounded grains roll more easily than angular grains. This sand dune in the Coral Pink Sand Dunes State Park, Utah shows secondary sand ripples along its slip face.

Wind more easily picks up particles on ground that has been disturbed, such as a construction site or a sand dune. Just like flowing water, wind transports particles as both bed load and suspended load. For wind, bed load is made of sand-sized particles, many of which move by saltation. The suspended load is very small particles of silt and clay.
