    Sandstorms (沙尘暴) happen suddenly and have effects on large areas. One example was a sandstorm on the Western  Route.

The wind speed reached 37. 9  m/s, and the visibility (可见度) was less than 50m. In Xinjiang,Gansu,Inner Mongolia and Ningx-ia,85 persons died and 264 were injured;4,412 houses were damaged,and 120,000 animals died or went missing. The direct economic  losses (直接的经济) were about 550 million yuan,which further damaged the environment and economic development.
