More than 7% of China's annual sand and dust weather occurs in spring. The most frequent month is April, followed by March and May.
The main domestic sources of sandstorms in China are concentrated in desert areas such as southern Xinjiang, Gansu Hexi Corridor, and central and western Inner Mongolia. Experts said that desertification control is not achieved overnight, and in the future, it is still necessary to strengthen vegetation restoration, reduce the frequency of dust weather and dust storm hazards.
