As the force of wind passing over loosely held particles increases, particles of sand first start to vibrate, then to saltate ('leap'). As they repeatedly strike the ground, they loosen smaller particles of dust which then begin to travel in suspension. At wind speeds above that which causes the smallest to suspend, there will be a population of dust grains moving by a range of mechanisms: suspension, saltation and creep.
