[Weather] Air quality is bad in most parts of the country.the effects of smog

While the concentration of ultrafine dust in various parts of the country is "bad," the air is expected to be murky in most parts of the country today (14th).

The National Institute of Environmental Research said dust accumulated as the atmosphere stagnated overnight and smog from China was introduced this morning, leading to a "bad" level of ultrafine dust concentration in most parts of the country.

However, from daytime, cold air will descend from the northwest, pushing dust southeast, and air quality is expected to recover to normal levels from the Midwest.
