[Weather] Tomorrow is sunny and cool...Until the morning, the west side is fine dust.

Tomorrow (22nd) will be mostly sunny and cool across the country, but in the morning, the concentration of ultrafine dust in some western areas will be somewhat high.

The National Institute of Environmental Research said that the atmosphere will stagnate overnight, with pollutants accumulating in fog, and smog will show a "bad" level of ultrafine dust concentration by morning, mainly in the Midwest, North Jeolla Province, North Gyeongsang Province, and Jeju Island.

However, from tomorrow afternoon, clean air will move south from the north and the spread of the atmosphere will be smooth, which will quickly eliminate ultrafine dust.

Tomorrow, the morning temperature in Seoul will be 3 degrees and the daytime temperature will be 10 degrees, which is lower than today.
