Traffic control is implemented in areas with serious sandstorms, and notices are issued to stop outdoor activities. Many cities canceled several flights.

In Beijing, students from Tsinghua University created the effect of "the blue sun looks like Mars". In Tianjin, a netizen commented: "The 1 17 building, which was once close at hand, has now become a sandstorm." In Hohhot, Inner Mongolia, many citizens found that houses with closed doors and windows could smell the soil. In Yulin, Shaanxi, according to the national sandstorm weather forecast map, sandstorms or low-pressure weather will also occur in parts of northwest Shandong. According to the forecast of Shandong Meteorological Observatory, from the afternoon of 15, pollution above PM 10 will gradually appear in Shandong Province from north to south. Meteorologists said that since March, the temperature in northern China has been relatively high, and meteorological conditions are generally conducive to the formation of dust weather. The sandstorm affecting northern China mainly comes from Mongolia, which developed vigorously (the central air pressure was 9800 Pa at 02: 00 on June 5, 65438). After the cyclone, the sandstorm moved southward under the action of cold high pressure, affecting most parts of northern China.

According to the comprehensive evaluation of satellite images and ground monitoring information of the Desertification Monitoring Center of the State Forestry and Grassland Bureau, the sandstorm entered the border between Mongolia and the central and western Inner Mongolia on the night of 14. Sandstorms occurred in Bayannaoer, Lianhaote and Baotou, Inner Mongolia, with visibility less than 1000m, PM 10 index over 500 μ g/m3, northwest wind 6-8, and air quality grades were all seriously polluted. China National Environmental Monitoring Center predicts that from the late night of 14 to the early morning of 15, due to the strong wind weather after Mongolia cyclone and before high pressure, sand blowing will occur rapidly in the border area between southern Mongolia and central and western Inner Mongolia, and cold air will move eastward rapidly, affecting eastern Inner Mongolia and western Jilin.

The comprehensive evaluation of satellite images and ground monitoring information of Desertification Monitoring Center of China National Forestry and Grassland Bureau also shows that the sandstorm weather mainly originated in Mongolia. 14 in the morning, a sandstorm occurred in southwest Mongolia. The sandstorm moved southward with the airflow and entered from the border between Mongolia and the central and western Inner Mongolia on the evening of 14. At present, sandstorms are still moving to the southeast, and are expected to affect Jilin, Heilongjiang, Henan, Shandong and other places one after another. According to the forecast of the Central Meteorological Observatory, there will be dusty weather in the southern Xinjiang basin, eastern Xinjiang, Inner Mongolia, southwestern Heilongjiang, western Jilin, western Liaoning, Gansu, Ningxia, northwestern Shaanxi, Shaanxi, Hebei, Beijing and Tianjin.
