A sand storm swept across large areas of Northern and Northeastern China during May 26 to 28, making it this year's longest lasting and most widespread in China.
According to a May 28 report from the Desertification Monitoring Center of China's Forestry Administration, the storm, caused by anticyclones from Mongolia and Southern Mongolia, hit hardest in Central Northern Inner-Mongolia.
From May 28, the dust started to spread into most of Northeastern China, Beijing, Tianjin, Shandong Peninsula, Henan and Hebei provinces.
The sandstorm influenced 537 counties and cities through a total of 10 provinces in most of Northern and Northeastern China and Henan and Shandong provinces, covering a vast area of 1.9 million square kilometers with 29 million hectares of farmland, 3.65 million commercial forests and 56 million hectares of grass land and a population of 270 million. The sandstorm has been a hazard to human health and traffic safety as well as farming and livestock breeding.
