What controls the different types of aeolian transport?

There are 3 main types of aeolian transport - suspension, saltation and surface creep. Suspension involves sand particles being carried within the air. Saltation is the bouncing of grains along the surface by the wind. Surface creep is the rolling or dragging of sand particles across the surface by aeolian forces. The main determinant of the type of aeolian transport that a particle experiences is its size. Suspension involves the smallest particles, <0.15mm in diameter. Saltation involves moderately sized particles, between 0.15 and 0.24mm in diameter. Surface creep involves the largest particles, >0.24mm in diameter.
