The sandstorm that disappeared within a few days has swept Beijing once again!
According to the China Weather Network, around 6 o'clock on March 28, the wind was very strong in the western and northern parts of Beijing, with gusts of magnitude 7 or 8 in some areas.
Affected by external sand and dust, it has reached a serious pollution level. In urban areas such as Haidian and Chaoyang, the air quality index "explodes" and the primary pollutant is PM10.
What is the double crit of strong wind + sand dust?
Xiaoxin went out and felt a wave.
