Abstract :

Donald Fryrear, a US Department of Agriculture Agricultural Research Service Conservation and Production Systems Research Unit (Big Spring, TX) supervisory agricultural engineer, discovered the transition from saltation to suspension (TSS) factor that is the genesis of dust storms. The TSS factor holds that heavy soil particles that are too heavy to be borne by the wind for more than a few feet fall back to earth and kick up lighter particles into the air. The TSS cycle, which takes place within 10 inches of the ground, repeats itself and creates a dust storm. Dust storms could be predicted in the future by tracing soil surface conditions.
