Dust in Iran
Tweet
Share

A large blanket of dust rolled southward over eastern Iran on May 27,
2021. The Moderate Resolution Imaging Spectroradiometer (MODIS) on
board NASA’s Terra acquired a true-color image of the spectacular storm
on that same day.

A system moving from west to east across the Caspian Sea and along the
border with Turkmenistan (north of the edge of the image) appears to be
the source of the wind that kicked up dust for more than 550 miles (885
km). In several areas, the dust is so thick that it obscures the land
from view.

Iran is mostly arid or semiarid, with deserts making up at least 25
million hectares (100,000 square miles) of the country’s area. Dust
storms are a common natural hazard. Sometimes called haboobs, dramatic
dust storms like this one are often associated with weather fronts and
may appear as walls of sand and dust marching across the landscape.
Haboobs tend to be abrupt and short-lived.
