Spectacular mammatus clouds spotted above Chinese city

Spectacular mammatus clouds were spotted above a city in northwest China. The rare scene, filmed in Ili Kazakh Autonomous Prefecture in Xinjiang Uygur Autonomous Region, shows the pouch-like clouds hanging in the sky. Mammatus clouds are also known as breast clouds. It's a cellular pattern of pouches hanging underneath the base of a cloud, which associates with hails and thunderstorms. The video was provided by local media with permission.
