For the first time this fall, ‘bad’ level of ultrafine dust appeared.
The cause is the overlapping of atmospheric congestion with smog from China, but it seems that the air strike of fine dust, which had been slowed down by the corona, has started again.

The clear autumn sky turned gray in one day.
Although the temperature is rising in the middle of the day, the visibility is still hazy, and the buildings around the river are trapped in dust and look stuffy.
The first ultrafine dust has arrived this fall.
The reason is that the air quality has worsened as the domestic air stagnation is added to the ultrafine dust that flowed in from China overnight.
Citizens who have been exercising as usual are only embarrassed by the sudden arrival of ultrafine dust.

The first ultrafine dust this fall appeared in most areas of the country.
In particular, in Incheon, Gyeonggi, and Gyeongbuk regions, the daily maximum ultrafine dust concentration exceeded 100㎍, which is three to four times higher than usual.
Most provinces across the country, including 77 in Seoul, 92 in Chungnam and 72 in North Jeolla Province, recorded the ‘bad’ level.
However, the first ultrafine dust this fall will not last long, and it is expected that all of it will be dissipated by the northwest wind overnight.
From then on, it is expected that the air will remain relatively clean until the end of this month.
However, it is highly likely that early cold and fine dust will appear repeatedly in the next month, making outdoor activities difficult.

In the coming months, weather patterns with repeated influences of continental anticyclones and mobile anticyclones may occur frequently, so preparation for not only the cold but also fine dust will be necessary.
In particular, from next month, as the transition to with corona takes place, there is a high possibility that the amount of domestic movement will increase again, resulting in an increase in fine dust.
Here in China, the situation is not easy.
This is because the amount of fine dust is expected to increase sharply when coal power generation is increased due to a power shortage and heating begins in earnest.
It seems highly likely that the air strike of ultrafine dust, which has stalled for two years in the aftermath of the corona virus, will reappear from this fall.
