It is predicted that on the 16th, strong yellow dust will also flow in following the climax of fine dust. The Meteorological Administration said on the 15th, “A strong wind of 50 to 70 km/h is blowing around Inner Mongolia and the Gobi Desert in China, and yellow dust has been widely occurring since the 14th. It was introduced in Korea from early morning or morning on the 16th, and yellow dust will be observed in most areas of the country in the morning.
Traffic safety attention due to rush hour
In Beijing, China, where the yellow dust first reached, the concentration of fine dust (PM10) soared to 6450㎍/㎥ on this morning and the sky turned yellow. As strong winds hit, more than 400 flights were canceled in Beijing alone. Chinese media reported that it was “the most powerful yellow dust in the last 10 years.”
It is expected that most of the ultrafine dust, which has been on the rise since last week, will be eliminated as a cold wind blows from the northwest from the night of the 15th. However, the air quality is expected to deteriorate again as yellow dust flows in immediately.
The Meteorological Administration predicted that heavy yellow dust could be observed, especially in western regions such as the metropolitan area. For the first time since April 2016, the Meteorological Administration predicts that there is a possibility of a’very dark’ yellow dust that lasts for more than 2 hours with an average concentration of 800㎍/㎥ or more per hour.
Meteorological Office forecast analyst Woo Jin-gyu said, “If yellow sand is additionally sourced from Dandong, China while moving to the Korean Peninsula, the concentration may increase.” .
Even on the 16th, the concentration of fine dust may soar to the level of’very bad’ due to the effect of yellow dust. From the 17th, the yellow dust will gradually weaken, but there are also observations that the yellow dust may lead to weaker afterwards depending on the flow of the barometer around the Korean peninsula.
