I thought fine dust went away… the worst yellow dust in the spring of tomorrow

The worst yellow sand for tomorrow

The midwestern region, including the metropolitan area, has been hazy for a week.
The atmosphere is congested, and the sky is hazy with fog in the morning and evening, and fine dust during the day.

There is no sign of any improvement today.
As of 12 o’clock, the concentration of ultrafine dust is’very bad (red)’ in the Midwest region, and’bad (yellow)’ in most other parts of the country.

Yellow dust also occurred strongly over the weekends as a result of being overwhelmed.
Looking at the weather map, there is a strong wind blowing between low and high pressures.
This strong wind has caused a very large amount of yellow dust in the Gobi Desert and Inner Mongolia.

The cyclone on the right is the cyclone that will send rain clouds to the central region tonight.
As high pressure expands behind rain clouds and a strong wind blows in tomorrow, it was expected that the ultrafine dust accumulated so far would be scattered and the air quality would be slightly better. However, as yellow dust occurs, the yellow dust will pour behind the rain clouds tomorrow.

Under the influence of this yellow dust, Beijing, China, issued a yellow dust yellow warning for the first time this spring.
It is said that the concentration of PM10, which can be regarded as the concentration of yellow sand, exceeded 2000㎍/㎥ in some areas at one time.
There was also a lot of traffic congestion on the way to work in the yellow sky. This yellow sand is expected to come into Korea tomorrow with the wind. Of course, the high concentration will not enter Korea as it is, but it is expected to be the strongest among the yellow dust that has been introduced this year.

Beijing, China this morning

Yellow dust, which was expected to affect the western region, has been shown to affect nationwide in recent forecasts. Due to the yellow dust, air quality in the western region is expected to be’very bad’ tomorrow, and’bad’ in most other parts of the country.
In particular, it is expected that it will come in the strongest between dawn and morning tomorrow when it escapes the influence of rain clouds.
