Image[bkeps.com]Wind isn't acting alone in the geological process behind erosion, sand dunes and airborne dust particles called aerosols. The other culprit is electricity. By taking both factors into account, researchers at the University of Michigan have developed a new model that matches real-world measurements of "saltation" better than the decades-old classical theory.
