Persian Gulf – March 6, 2013

Dust blows northward off the coast of the Arabian Peninsula and over the Persian Gulf. The plume appears to originate in the Rub al’Khali, a sandy desert in the southern part of the peninsula, and blow northwards across southeastern Saudi Arabia, then eastwards, east of Qatar and along the coast of the United Arab Emirates.

Saudi Arabia – February 19th, 2013

The Rub’ al Khali or Empty Quarter is the largest sand desert in the world, encompassing most of the southern third of the Arabian Peninsula, including most of Saudi Arabia and areas of Oman, the United Arab Emirates, and Yemen. The desert covers some 650,000 square kilometres (250,000 sq mi).

The desert is 1,000 kilometres (620 mi) long, and 500 kilometres (310 mi) wide. Its surface elevation varies from 800 metres (2,600 ft) in the southwest to around sea level in the northeast. The terrain is covered with sand dunes with heights up to 250 metres (820 ft), interspersed with gravel and gypsum plains.

The sand is a usually reddish-orange color in some areas due to the presence of feldspar. However, here, its sands appear bright whitish tan in color here due to the infrared bands of the sensor used to capture the image.┬áThere are also brackish salt flats in some areas, such as the Umm al Samim area on the desert’s eastern edge.

India and Pakistan – December 28th, 2012

Dust blows over Afghanistan (top center) and off the coasts of Iran (left) and Pakistan (right). Air currents cause it to form long, parallel rows rather than an indistinct cloud. The dust reaches far over the Arabian Sea, where it is then swept westwards towards the Arabian Peninsula.

Dust Over Southern Red Sea

Red Sea – August 30th, 2012

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. Here, there appears to be a transference of dust between the Sahara Desert in Africa and the drylands of the Arabian peninsula. Both regions are the main terrestrial sources of airborne dust.

Dust Near Dahlak Archipelago in Red Sea

Red Sea – August 30th, 2012

Dust blows across the southern half of the Red Sea, appearing thickest below the Dahlak Archipelago, off the coast of Eritrea. Due to the wide spread of the dust cloud across the sea, it is difficult to discern whether its point of origin is the Sahara Desert, on the African continent, or the Rub al’Khali desert, on the Arabian Peninsula, or a mixture of the two.
