Sand can only be moved by strong, steady winds. The air must be moving at least 15 miles per hour to be able to pick up sand grains. In the Tularosa basin, it is primarily between February and April that the winds are strong enough. These winds are called unidirectional winds because they always move in the same direction, from the southwest to the northeast. As the wind blows, it pushes the sand ahead of it, so individual dunes are slowly moving to the northeast.
