The snow stops gradually, but icy roads are made all over the place in the cold.

It snowed or rained everywhere today.

Snowfall will stop gradually, but caution is needed as the snowy rain in the cold will freeze and ice roads will be created.

Let's take a look at the detailed snow conditions and cold prospects with caster Kim Soo-hyun.

Hello.

The first snow poured so much that it was called a snow bomb, and it continued for a long time. Is there a place where it snows now?

[Caster]
Yes. I'll explain it while looking at the current radar situation.

You can see green and blue on the current screen. The blue part can be seen as an area of light snow or raindrops,
The green part of
is the area where snow rains.

So, it can be seen that it is snowing or raining in the metropolitan area including Seoul, Chungcheong, Honam, and Yeongnam inland.

Fortunately, we don't have much time and quantity to get off today.

First of all, most of the snow will stop around 9 p.m.,

Only some coasts in Chungbuk, northern Gyeongbuk, and Honam will fall a little more until late at night.

The expected amount of snow will be 1 to 3cm and the amount of rain will be around 5mm.

Unlike yesterday, it falls lightly today, is there a reason?

[Caster]
First of all, let me explain the reason why the snow bomb fell.

The center of the cold air was on the upper floor in Korea the day before yesterday and yesterday.

The cold air is spinning through our country,

As the atmospheric flow was not smooth and stagnated, cold air continued to flow into Korea.

As this cold air passed through the sea, the sea level, or the temperature difference between the sea level and the atmosphere, led to the development of snow clouds.

However, the sea level temperature is maintained at 1 to 3 degrees higher than usual.

That's why the snow clouds developed stronger as the sea difference widened.

In addition to the snow clouds that have developed in the West Sea, there was a lot of water vapor in the atmosphere, even though it was late November.

If the temperature is high, the amount of water vapor that the atmosphere can hold increases.

There was a lot of water vapor in the atmosphere because the temperature continued to be high due to the unusually high temperature phenomenon.

On the other hand, today, as the atmospheric congestion was resolved, the center of the cold air escaped to the northeast.

A weak pressure bone was created at the back of this cold air, causing the snow to fall weakly.

It's gotten a lot colder today as the snow subsides, but why did it get so cold all of a sudden?

[Caster]
Let's start with this morning's temperature.

Anheung-myeon, Hoengseong-gun, Gangwon-do, recorded the lowest temperature today.

It fell to -16.3 degrees, and the official record showed that Daegwallyeong was the lowest at -11 degrees.

And Jecheon, Chungcheongbuk-do, fell to -9.8 degrees Celsius and Seoul to -3.4 degrees Celsius, showing the coldest weather ahead of winter.

The first reason for the cold weather is that cold air has been continuously introduced.

The second reason was that the radiation cooling effect increased.

As you can see on the screen, when clouds cover the sky, heat cannot escape like a blanket and shows a warming effect.

Over the last night, as the clouds disappeared, more heat was released, so the radiation cooling effect was greater.

And the snow piled up without melting also affected.

When snow is piled up, the moisture from the snow flies into the air and loses heat, so the temperature drops further.It is similar to the principle that when you put alcohol on your

hands, it instantly cools down as it flies.

How about tomorrow? Will it be cold tomorrow?

[Caster]
Not as much as today, but it is expected to be quite cold tomorrow morning as well.

Tomorrow morning in Seoul, temperatures will drop to -1 degrees Celsius, Cheorwon -5 degrees Celsius, and Daejeon 0 degrees Celsius, and the cold is expected to be below zero in the central region.

It is expected that there will be many places where melted snow or falling snow will freeze as the temperature drops significantly.

In addition, road thin ice, called 'black ice', can be made at 2 to 4 degrees in video.

In other words, thin ice can appear on roads all over the country, so caution is needed.

In particular, it is easy to make thin ice behind large buildings in the north, in the shadowy areas of mountain corners, in the entrance and exit of tunnels, and on piers, so you should be more careful when passing through this area.

It is of utmost importance to double the speed and double the safety distance than usual.

And there may have been cases where accidents occurred because you could not avoid thin ice.

Secondary accidents often occur while trying to deal with accidents such as setting up tripods.

First of all, it is the top priority for drivers and passengers to evacuate safely off the road while looking at the vehicles behind them.

After that, it would be better to contact the fire station or police station, and when safety is secured, install a safety tripod or a scintillator to inform the vehicle that comes behind it of the danger.

By day tomorrow, the cold is expected to ease.

Raindrops and snow are expected to fall or fall overnight in the central region from tomorrow afternoon.

Please continue to be careful as there may be places where thin ice is made on the road tomorrow night.
