Snowfall will gradually stop, but caution is advised as 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 outlook with pitcher Kim Soo-hyun.

Good morning.

The first snow fell so much that it was called a snow bomb, and it lasted a long time. Is there anywhere it’s snowing now?

(Roulette)
Yes. I will explain it by 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 it rains snow.

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

Luckily we don’t have much time or quantity to go down today.

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

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

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

Unlike yesterday, it is falling slightly today, is there a reason?

(Roulette)
First, let me explain why the snow bomb fell.

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

Cold air crosses our country,

As the atmospheric flow was not steady and stagnated, cold air continued to flow towards Korea.

As this cold air passed across the sea, sea level, or the temperature difference between sea level and the atmosphere, caused snow clouds to develop.

However, sea level temperatures are maintained between 1 and 3 degrees above normal.

This is why the snow clouds grew stronger as the sea difference widened.

In addition to the snow clouds that formed 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 as the temperature remained high due to the unusually high temperature phenomenon.

In contrast, today, as the atmospheric congestion was resolved, the center of cold air escaped to the northeast.

A weak bone of pressure was created behind this cold air, causing little snow to fall.

It’s a lot colder today as the snow has eased, but why did it get so cold all of a sudden?

(Roulette)
Let’s start with the temperature this morning.

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

The temperature dropped to -16.3 degrees and the official record showed Daegwallyeong was the lowest at -11 degrees.

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

The first reason for cold weather is that cold air is continually being introduced.

The second reason was that the cooling effect of radiation increased.

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

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

And the snow accumulated without melting also affected.

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

hands, it instantly cools when flying.

And tomorrow? Will it be cold tomorrow?

(Roulette)
Not as much as today, but it should be quite cold tomorrow morning as well.

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

There are expected to be many locations where sleet or falling snow will freeze as the temperature drops significantly.

Additionally, thin ice on the road, called “black ice”, can be created at a temperature of 2 to 4 degrees in video.

In other words, thin ice may appear on roads across the country, so caution is advised.

In particular, it is easy to form thin ice behind large buildings in the north, in the shadow areas of mountain corners, at the entrance and exit of tunnels and on pillars, so you need to be more Be careful when crossing this area.

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

And there may have been cases where accidents occurred because it was impossible to avoid thin ice.

Secondary accidents often occur when trying to handle accidents such as setting up tripods.

First, the top priority for drivers and passengers is to safely exit the road while watching for vehicles behind them.

After that, it is better to contact the fire station or police station, and when safety is assured, install a safety tripod or scintillator to inform the following vehicle of the danger.

Tomorrow the cold should ease.

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

Please continue to use caution as there may be areas where thin ice forms on the road tomorrow evening.
