Persian Gulf - May 31st, 2012

Close-up of Iraq

Dust can be seen blowing over Iraq, as well as over Kuwait and the northern reaches of the Persian Gulf, in this image of the Middle East. The close-up offers a more detailed view of the dust where it is thickest – over the valley around the Tigris and Euphrates Rivers. The dust does not spread northward to the Caspian Sea, partially visible at the top of the image.

Dust Between Iraq, Lake Van and the Caspian Sea

Caspian Sea - May 21st, 2012

Dust blows northward from Iraq towards Turkey and northwestern Iran. Here, two main clouds of dust can be observed: one between Lake Van (left edge) and the Caspian Sea (right edge), and the other near the Iraq-Iran border, east of the Tigris and Euphrates River Valley. While the land below those two main dust clouds is almost completely obscured, Lake Tharthar can be seen through a thinner veil of dust at the lower left.

Iraq - May 6th, 2012

The Shatt al-Arab, literally meaning “Coast/Beach of the Arabs”, is a river in Southwest Asia formed by the confluence of the Euphrates and the Tigris in the town of al-Qurnah in the Basra Governorate of southern Iraq. The southern end of the river constitutes the border between Iraq and Iran down to the mouth of the river as it discharges into the Persian Gulf.

The river is approximately 200 km (120 mi) in length. It varies in width from about 232 metres (761 ft) at Basra to 800 metres (2,600 ft) at its mouth. The Karun River, a tributary which joins the waterway from the Iranian side, deposits large amounts of silt into the river; this necessitates continuous dredging to keep it navigable. Here, sediments from the rivers can be seen pouring into the northern end of the Persian Gulf.

Dense Cloud of Dust Over Persian Gulf – March 23rd, 2012

Dust Over Arabian Peninsula - March 18th, 2012

A thick cloud of dust blows over Iraq, Kuwait and northern Saudi Arabia. The dust obscures much of the Persian Gulf (right), virtually all of the valley by the Tigris and Euphrates Rivers, and impedes the view of Lake Tharthar (left). This dust storm has been moving huge amounts of sand and dust particles about the Middle East and Asia over the last week (click here for previous images).

Dust Over Iraq - March 1st, 2012

A dust storm or sand storm is a meteorological phenomenon common in arid and semi-arid regions. Here, dust can be seen spreading over Iraq, between the Tigris and Euphrates Rivers. A sandstorm can transport large volumes of sand unexpectedly, with the leading edge being composed of solid wall of dust as much as 1.6 km (0.99 mi) high.

Dust storms cause soil loss from the dry lands, and worse, they preferentially remove organic matter and the nutrient-rich lightest particles, thereby reducing agricultural productivity. Also the abrasive effect of the storm damages young crop plants. Other effects that may impact the economy are: reduced visibility affecting aircraft and road transportation; reduced sunlight reaching the surface; increased cloud formation increasing the heat blanket effect; high level dust sometimes obscures the sun over Florida; effects on human health of breathing dust.
