A dust storm or sand storm is a meteorological phenomenon common in arid and semi-arid regions.


Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface.


Particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another.

 




Dust Storms are a natural phenomenon that have made life in Australia uncomfortable for many years. This photo was taken in Broken Hill NSW in 1907.
