Ryn Desert
The Ryn Desert or Ryn-Peski Desert (, Naryn-Qūmy; ) is a desert in western Kazakhstan and Astrakhan Oblast, Russia.

High winds sweep across the desert, and in 2001 a dust storm in the Baltic Sea was determined as originating in the Ryn Desert. A study of long-range dust transportation to the Baltic Sea region—by analyzing dust pollution in Scandinavia, showed that aerosol concentrations there were influenced more by the Ryn Desert region than the Sahara Desert in Africa.

Many small towns are scattered throughout the Ryn Desert, and population density is between 1 and 15 people per square mile. Aralsor lake lies at the northern edge. The desert lies in a semi-arid climate zone, and receives very little rainfall.
