[Weather] The weather changed suddenly in a day...Winter starts like this?

[Anchor]
Unlike last week, when it was warm, cold weather like winter came today.

This cold won't last long, but as it's gradually moving on to winter, it seems necessary to prepare for the cold in the future.

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

It was really cold this morning. How much did the temperature drop?

[Caster]
I think many people must have been embarrassed by the early cold coming on the way to work today.

The coldest place in the country today was Hyangrobong in Goseong, Gangwon Province. It dropped to -10 degrees.

Seolcheonbong Peak in Muju, North Jeolla Province also fell to -9.4 degrees.

Official records show that Daegwallyeong was the lowest at -6.1 degrees,
There were many places that recorded below zero, such as
Seoul -0.7 degrees.

In addition, the wind was strong, and the cold felt even worse.

As the temperature dropped significantly, a cold wave warning was issued for the first time this fall in Muju, Jeollabuk-do, Jangsu, and Jinan.

Since the first cold wave warning was issued in the mountains of northern Gangwon Province on the 19th of last month,

A cold wave warning was issued for the first time this fall in southern Gangwon, Chungcheong, Honam, Gyeongnam, and Jeju.

As the peak of this cold was today, all cold wave warnings have been lifted as of 10 a.m. today.

However, the temperature in the central and northern regions was lower, but more special warnings were issued in Chungcheong and southern regions, right?

[Caster]
You might think it's a little strange. This is because of the cold wave special report's criteria.

There are two conditions for the cold wave warning to take effect. First, it goes into effect when the morning minimum temperature is expected to drop by more than 10 degrees from the previous day, less than 3 degrees, and 3 degrees lower than the average year, so all three conditions are met.

Another thing is the conditions that mainly correspond to the middle of winter.

It is lowered when the morning minimum temperature is expected to last more than two days, below -12C.

Therefore, it is lowered to warn in advance when temperatures drop sharply or when a strong cold wave is expected to continue for a long time.

However, if you compare Seoul, where the cold wave warning was not issued, Busan, and Muju, where the warning was issued, Seoul has already decreased by 8 degrees between the day before yesterday and yesterday, that is, between Saturday and Sunday.

From yesterday to today, it has decreased by about 8 degrees again.

As the temperature decreased twice, it did not meet the standard of the special report.

On the other hand, warnings and warnings were issued as Busan fell by 10 degrees and Muju by 15 degrees.

What's the reason why it's so cold?

[Caster]
The reason is the inflow of cold air from the northwest.

The cold air below -20 degrees Celsius near the upper level of 5 kilometers came down to the Korean Peninsula, lowering the temperature.

In fact, this cold was not very strong.

This morning's temperature is only 1 to 3 degrees lower compared to this time in previous years.

But it was really warm until last weekend.

It was 7-10 degrees higher than usual, and warm weather continued like spring in late April.

That's why even though it was mid-November, some people dressed in short sleeves in the middle of the day stood out.

After such warm weather, the temperature suddenly dropped significantly, so it felt very cold.

Also, it is not unusual for such early cold to appear in late autumn.

A typical late autumn weather is when the high and low pressures alternate, with a pattern of rain falling once and cold air flowing in behind a rain cloud.

Then how long will the cold continue?

[Caster]
This cold won't last long.

Tomorrow morning's temperature in Seoul will be 0 degrees, and cold weather will continue until tomorrow morning, but

The cold is expected to ease tomorrow as it recovers to normal levels.

However, it's a time when it's gradually turning into winter.

Based on Seoul this week, the average temperature in the morning is 1 to 2 degrees, and the average temperature in the daytime is 10 degrees, so even if it is at an average level, the air is quite cold.

Temperatures temporarily rise to 7 degrees on Thursday morning, but generally similar to previous years, the weather will continue to be somewhat cold on the way to work.The daytime temperature of

is also around 10-13 degrees Celsius, which is similar to or slightly higher than in previous years, and it is now expected to continue to be quite chilly in the middle of the day.

If it gets colder, I think I should pay more attention to health care, so what should I pay more attention to?

[Caster]
Cardiovascular disease is the most important disease to watch out for when the weather gets cold.

According to the data from the National Statistical Office, the second-largest cause of death last year was heart disease, the fourth-largest cerebrovascular disease, and the eighth-largest hypertensive disease, so more attention is needed because it occurs frequently and can lead to death.

To prevent cardiovascular disease, it is recommended to exercise regularly.

Rather than reducing your activity because it's cold, lowering blood sugar through proper exercise and maintaining weight help prevent cardiovascular disease.

However, it is recommended to refrain from exercising at dawn or at night when the temperature is low.

It is also recommended to lower the intensity of exercise by 10 to 20% lower than usual to 60% of the maximum exercise.

And when you go out, wear a hat and gloves to warm your body,
It is also good to reduce indoor fine dust by ventilation in between
.

And it is of paramount importance to refrain from smoking and drinking,

It is said that eating enough fruit, body fat, and fish is more helpful than stimulating and greasy food.

Please keep that in mind.
