What is a sandstormSandstorm refers to a disastrous weather phenomenon in which strong winds roll up a large amount of sand and dust from the ground and make the air turbid, which has the characteristics of suddenness, short duration, small probability and great harm.
Most of the areas affected by sand and dust in China are concentrated in the north, mainly in spring. During this season, most of the northern region has cyclonic and windy weather, low precipitation, dry air and topsoil, and bare ground, which has the conditions for sandstorms. The wind rolls the dust and sand particles into the air, making the air turbid and the visibility significantly reduced.
According to the visibility level and severity, sand and dust weather can be divided into five categories: floating dust, blowing sand, sand and dust storm, strong sand and dust storm, and extremely strong sand and dust storm. Dust weather with horizontal visibility of less than 1 km is a sandstorm.
