Wind transports sand grains mostly as part of the bed load and sometimes as suspended load. When wind energy is sufficient, it can lift and roll sand grains along the surface, which is referred to as saltation, and it's the primary method for sand grain movement in a wind-dominated environment. While suspended load is also possible, especially with finer particles like dust, sand grains are typically too heavy to be suspended in the air for long periods or distances and are more commonly moved by bouncing along the ground. Severe dust storms can suspend a large mixture of fine particles, including sand, but for typical sand grains, they are predominantly part of the bed load.
