[Weather] It's sunny tomorrow, but 'ultra-fine dust' in the west of the morning...From the afternoon, the wind will blow away.

Tomorrow (22nd) will be mostly sunny 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 the atmosphere will stagnate overnight and the concentration of ultrafine dust in western regions such as the Midwest and Jeonbuk will be "bad" in the morning due to smog from China.

However, from tomorrow afternoon, clean cold winds 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 is 3 degrees and the daytime temperature is 10 degrees, which is lower than today, so it will be relatively chilly.
