July 2, 2011 - Dust storms in Iraq
Tweet
Arising along a roughly northwest-southeast line, multiple dust plumes blew southeastward through Iraq at the end of June 2011. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this natural-color image on June 30, 2011.
In this image, Turkey is located in the upper left (west) corner and Iran in the upper right (east). Moving south, Syria lies in the west and Iraq sits between Syrian and Iran. Saudi Arabia lies to the south of Iraq, with Kuwait lying between the two. The Caspian Sea can be seen in the upper edge of the image and the Persian Gulf is to the south.
A large plume with indistinct margins appears near the Syrian border and blows southeast over Buhayrat ath Tharthar (Lake Tharthar). Fine sediments along the southeastern shoreline of this impermanent lake give rise to another thick plume of dust. Closer to the Persian Gulf, more plumes arise. As in another dust storm on June 19, the plumes in southeastern Iraq vary in color from beige to dark brown.
Along the shoreline of the Persian Gulf, dust is thick enough to completely hide the land and water surface below. Dust of varying shades of tan and beige completely covers Kuwait.
Dust storms in Iraq often owe their existence to heat and silt. Besides impermanent lakes such as Buhayrat ath Tharthar, the river valleys of the Tigris and Euphrates hold fine sediments that can easily be stirred. As daytime temperatures rise, especially in the summer, air near the ground becomes unstable, enabling even light winds to loft dust particles into the air. Baghdad temperatures reached into the 90s Fahrenheit (about 35 degrees Celsius) late in the day on June 30, 2011, and temperatures in early July were forecast to top 100 degrees Fahrenheit (38 degrees Celsius).
