GREAT NATURE -- Black Storm: The Gobi Desert

Synopsis
The Gobi Desert, which stretches from northern China to southern Mongolia, is one of the world's greatest inland deserts. Every spring, fierce sandstorms hit the area. Locals call them "black storms." The swirling sand blocks out the sun, causing the temperature to drop, and day turns into night. Wind speed sometimes reaches over 20 meters per second. This program, which covers the storm in HD for the first time, also reveals the mechanism that generates these storms.
