1. Background

One typical example was an especially severe sandstorm on the Western Route in 1993, affected by cold air from Siberia. It moved quickly southward from May 4 to 6, 1993, affecting a total area of 1.1 million sq km, from northern Xinjiang to the Hexi area of Gansu, western Inner Mongolia and most of the Ningxia Hui Autonomous Region. The wind speed reached 37.9 m/s (greater than a Force 12 wind). The average wind speed was 21m/s (equal to a Force 8 wind), and the visibility was less than 50 m. The sandstorm caused great losses. In Xinjiang, Gansu, Inner Mongolia and Ningxia, 85 persons died and 264 were injured, 4,412 houses were destroyed, and 120,000 animals died or went missing. About 373,333 million hectares of crops were destroyed, over 2,000 km of ditches were buried, and transportation and telecommunications facilities were severed in some areas. The direct economic losses hit 550 million yuan, which further damaged the ecological environment and economic development.
