A sandstorm hit Gansu Province, Inner Mongolia Autonomous Region (内蒙古自治区) and Beijing on Sunday, reducing visibility (能见度) to less than 100 meters in affected areas. When visibility drops to less than 1 kilometer, it is called a sandstorm. The sandstorm in Minqin blew up dust in neighboring towns, such as Baiyin, Wuwei, and Jinchang.
Dust winds also swept into Beijing at more than 20 meters per second. Dust first reached the capital’s suburbs at 7 a.m., downtown areas at 9 a.m. The Palace Museum in central Beijing was covered in thick, brown-yellow dust at noon. The winds, which died down during the night, brought the temperature down to 8℃ below zero and many flights put off their planned time from the city’s airport.
Although the Chinese Central Weather had forecast the sandstorm on Tuesday and warned citizens to prepare for it, many people were shocked by the yellow sky. Wang Hongsheng, a senior citizen living in Beijing for more than 60 years, said such weather had seldom been seen in recent years. In the northwestern part of the city, the sky was darkened by the sand, forcing cars and shops to turn on their lights.
It is quite rare for sandstorms, which are frequent between March and June, to happen in winter, when the earth is frozen. The sandstorms in Gansu and Inner Mongolia do not necessarily mean there will be more of them in the spring than last year, but Beijing is taking it very seriously. It is reported that Beijing will spend 6 billion yuan in preventing sandstorms in the capital and has already set up a special team to make sure what causes them.

Considering that there was no better way.
