Saltation is the process of wind blowing grains of sand across a landscape, sending them bouncing against the ground and each other. The bouncing motion of the saltating grains on the soil bed kicks dust aerosols into the air.
This new knowledge could lead to better climate models because it helps scientists understand how aerosols are released, U-M researchers say. Dust is one type of aerosol. Burning fossil fuels releases another type. They are known to affect Earth's climate by blocking and absorbing sunlight and seeding clouds…..
