Chaoyang and other areas in western Liaoning have experienced nine droughts in ten years. Talk about the reasons of insufficient rainfall. This year, the farmland failed again.

The Yanshan Mountains block the warm air flow from the Bohai Sea, so it is difficult for water to reach western Liaoning and Inner Mongolia. After the north wind from Siberia passed through Mongolia and Inner Mongolia, the water disappeared. In addition, there are few rivers on the ground and little vegetation coverage, so it is difficult to form heavy rainfall.
