| Abstract: | The sand-dust weather is a typical disastrous weather,which can be divided into three categories:sandstorm,blowing sand and floating dust.Sand and dust weather usually occurs in the semi-arid,arid and desert area.The formation of dust storms to be three basic conditions:First,high winds.The other is the ground bare sand material.Three are unstable air.Days with sand dust are attributed to the background of large-scale circulations.In addition to this,it is related to climatic factors.In northern China is th... |
