Fanning is done by the wind in sandy dunes. ... The wind hurries up when it meets the slope of a dune, permitting it to carry even more quantity of sand. It is observed that the size and spacing of dunes increases as the velocity does. Also, the greater the velocity, the bigger the grains it can carry
