Drifting sand
Drifting sand (seen at 1 and 2) is defined as sand raised by the wind to small heights above the ground. The motion of the particles of sand is more or less parallel to the ground. Note that while objects on the ground may be veiled or hidden by the moving sand, the horizontal visibility is not sensibly diminished at eye level (1.8 m above the ground).

Drifting sand
In the image, a strong and gusty wind from the sea (blowing from right to left on the picture) is causing sand to drift from the beach with some force along the ground, but mainly to a height of less than 1.8 m. Near the ground, the sand begins to veil the objects some metres away, but the horizontal visibility at normal observation level is not reduced.

Foehn wall and drifting dust
This picture was taken from a location in Argentina to the east of the Andes mountain range during a foehn wind event. There are two main features in the image:

1) The large band of cloud over the mountains is known as a foehn wall. The foehn wall is a cloud formation which, during an episode of foehn winds, lies over and along a mountain ridge and which appears to an observer downwind from the mountains as a wall or bank of cloud. The foehn wall marks the eastern limit of the cloud that exists over the windward side of the mountain range.

2) The warm, dry downslope foehn wind (known locally in Argentina as the Zonda wind) is strong enough here to raise dust to a small height above the ground. This is known as drifting dust.
