Strong winds blowing over loose soil or sand can lift up large amount of sand or dust, and cause very low visibility, a phenomenon called “sand/dust storm”. These usually appear in grayish yellow on true colour satellite imageries. An animation of satellite imageries on 3 and 4 May 2017 shows the spread of sand/dust storms to the east over the Badain Juran Desert in northern China. (The imageries were captured by Himawari-8 satellite of Japan Meteorological Agency)
