Dust storm

Dust storm is a meteorological phenomenon where strong winds lift up and transport dust particles in a storm. These mainly occur in arid and semi-arid regions. These storms carry dust, as opposed to the larger sand grains, that are finer and are hence transported over longer distances. When the particle size is lesser than 10 micrometer they pose serious health hazards to people as they can enter deep into the lungs. Recently, a major dust storm hit Beijing.
