摘要

Movement of mineral dust by the atmosphere has been underway for ages, but efforts to assess its magnitude and significance have come largely in the last century. Attempts to identify and understand effects of the dust on soils are even more recent, mostly in the last 30 years. Airborne movements have several forms. Dust is transported by large storms that can be spectacular. Dust is also moved by smaller pulses and in a rather continuous flux. Most movement is within continents or from continents to nearby oceans, but fine dust (fine silt and clay) is carried from one continent to another. Prime sources of the dust are the deserts and semi-arid regions of the world. For example, large quantities of dust are carried out of the Sahara every year.
