Scary red sky blankets city in China after extreme dust storm


A scary red sky blanketed a city after an extreme dust storm in China.

Footage shows a road enveloped in an eerie red colour after a massive sandstorm struck the area located near the harsh Gobi desert in Dunhuang City, Gansu on August 2.

The red sky obscured visibility in the area as well as surrounding villages the entire day before the clouds slowly dissipated.

Dust storms commonly originate in hot, dry regions and are caused by strong pressure gradients over large areas. They are usually red in colour due to the iron oxide content in the sand, which absorbs blue light and reflects red light.
