The birth of a dune
by Chiara Arrighi, University of Florence, Florence, Italy
Wind moves the grains of sand until an obstacle causes the sand to lose momentum and settle. This is the process that allows a dune formation. In the picture you can see some 'baby' dunes and imagine the structure of air vortices behind the obstacle.
