On January 13, many cities in the central and western Inner Mongolia Autonomous Region, including Alxa League, Ordos City, Baotou City, and Hohhot City, were hit by sand and dust weather.
According to the monitoring of the Department of Ecology and Environment of the Inner Mongolia Autonomous Region, at 14:00 on the 13th, the air quality index of Ordos, Hohhot, Bayannaoer, Ulanchabu, and Baotou reached the top value of 500, and the air quality was seriously polluted.
China Environmental Monitoring Station predicts that from the 15th to the 16th, due to the influence of the systemic cold high pressure southward and the northerly cold air process in the direction of the northeast Bohai Bay, the diffusion conditions will improve, and the impact of the sand and dust process in North China and Northwest China will gradually tend to End.
According to a report from the Central Meteorological Observatory, starting from January 10, sand or dust has occurred in central and western Inner Mongolia, central and northern Gansu, Ningxia, northern Shaanxi, Shanxi, southern Hebei, and northern Henan. Minqin, Gansu and Wulatehouqi, Inner Mongolia Sandstorms occur in other places, and the minimum visibility is 300 meters; the local peak PM10 concentration in central Inner Mongolia exceeds 1000 micrograms/m3.
