Saudi Arabian desert
Saudi Arabian desert. Combined infrared and visible satellite image of the Jabal Tuwayq ridge (down centre) in the rocky desert region of Najd in central Saudi Arabia. North is at top. Jabal Tuwayq is a ridge that extends for hundreds of kilometres. It is the western edge of a large escarpment, and rises up to 250 metres above the plain to its west. Numerous dry water courses (wadis) are seen draining the ridge to the east. The image is 185 kilometres wide. Photographed by Landsat 1 on 24th September 1972.

Dust plumes blow off the coast of Saudi Arabia and over the Red Sea
January 15, 2009 - Dust plumes blow off the coast of Saudi Arabia and over the Red Sea. The largest plume blows off the Saudi Arabian coast north of Jiddah (or Jeddah), forming a counter-clockwise arc that barely misses the Sudanese coast. Along the northwestern margin of this plume, tendrils of dust form lines roughly perpendicular to the plumeas arc. These tendrils may arise from different air currents at different altitudes. Another relatively large plume blows over the Red Sea to the north, forming wavy lines that dissipate midway over the Sea.
The dust plumes arise from fine sediments along Saudi Arabiaas west coast, and many source points appear in this image. Although these dust plumes are from Saudi Arabia, dust can blow over the Red Sea from either direction. Dust plumes from Sudan also occur regularly in this region. Inland from the coast, the land surfaces of both Saudi Arabia and Sudan appear rugged and rocky, darker in color from the fine sediments that can easily give rise to dust plumes.
