There was very thick fog all over the interior of this morning's commute.

However, it is predicted that clear skies will be revealed during the day, and autumn weather will continue on weekends and holidays with clear and wide daily temperatures.

Let's take a closer look at the weather science and technology with caster Yoon Soo-bin. Hello!

The fog was very thick this morning.

What's the situation like now?

[Caster]
Yes, 'morning fog' was also rampant throughout the interior today.

The visibility has been narrowed to less than 200m.

In particular, low-correction warnings were issued at Cheongju Airport and Gwangju Airport.

If you look at the real-time fog situation while looking at the YTN disaster reporting system Idas screen.

It's near Oksan, Chungbuk on the Gyeongbu Line.

It's cleared up a little more than at dawn, but the sky is still cloudy like this, so the view is stuffy.

This is near a rock on the Dangjin Line in Daejeon.

It's still very hazy here as well.

The view is likely to be this stuffy until around 10 a.m., so you'd better be careful about traffic safety.

Let's take a look at the cause of the fog.

If you compare the amount of water vapor that the air can hold to a bowl, this bowl gets bigger as the temperature increases.

Therefore, when the temperature rises during the day, the bowl becomes large like a basin.

On the other hand, at night, the temperature drops significantly, making the bowl as small as the rice bowl again.

Overnight, water vapor cannot be contained in a small bowl, and it is fog that floats as water droplets in the air.

That's why the fog is especially thick when the daily temperature difference widens by more than 10 degrees.

This increases the risk of traffic accidents.

In particular, most of the large-scale vehicle chain crashes, such as the 106th crash of Yeongjong Bridge in 2015, were caused by fog.

I'm also curious about the weather this weekend and holiday. How is it?

[Caster]
Yes, I think there will be many people planning outdoor activities for the weekend in the ripening autumn weather.

It's generally clear and cozy, so it's good to go out.

This weekend and holiday, the morning temperature in Seoul will be 13 degrees, but the temperature will rise significantly compared to the morning with warm autumn sunlight during the day.

Tomorrow's midday temperature in Seoul is 24 degrees, and the day after tomorrow is 25 degrees, so if there is a lot of activity, it can feel a little hot.

[Anchor]
Are there any precautions for outdoor activities on the weekend?

[Caster]
Yes, as I mentioned earlier, those who are going to travel in early morning vehicles should pay attention to the fog.

Especially on roads near rivers and lakes, fog can become thicker.

Please slow down more than usual.

It's a good idea to keep enough distance between cars.

Also, caution is needed in the large daily temperature difference.

The temperature difference between morning and day, day and night will widen by more than 10 degrees.

As it is easy to get respiratory diseases such as colds in this weather, please pay attention to body temperature control with outerwear that is easy to wear and take off.

Finally, it's a high wave.

For the time being, the waves are expected to be high on the coast of Yeongnam and Jeju Island.

You should be careful not to cause coastal safety accidents.

It's already mid-October, but typhoons are still being made?

[Caster]
Yes, on the 9th, the 19th typhoon 'Barijat' occurred on the Hangul Day holiday.

The intensity of the typhoon is not strong and it is far from Korea, so it will not affect the Korean Peninsula.

Looking at the typhoon's path, the 19th typhoon 'Barizat' is currently moving northward from the sea about 1,100 kilometers southeast of Sapporo, Japan.

By this afternoon, it is expected to weaken to a temperate low pressure.

Therefore, there will be no impact on our country, but there is a possibility of a typhoon like this for the time being.

I need to pay a little more attention.

Is there a place where the first autumn leaves bloom in the clear autumn weather?

[Caster]
Yes, that's right.

The first foliage refers to when about 20% of the leaves are red from the top of the mountain.

The first autumn leaves began on Mt. Seorak on the 4th.

This is 4 days later than last year and 6 days later than usual.

The first autumn leaves were then observed in Odaesan Mountain.

Other mountains are expected to start changing their red clothes gradually.

The peak of autumn leaves usually appears about two weeks after the first autumn leaves begin.

This year, Mt. Seorak will have its peak of autumn leaves from the 20th, and Mt. Bukhan will be able to meet the splendid autumn mountains on October 30 and Mt. Naejang in early November.

With the full-fledged autumn leaves season, I think there will be many people planning to hike.

Except for Jeju and parts of the South, most inland areas have no clear rain news for the time being, so the atmosphere is expected to dry up gradually.

When hiking, please manage the embers thoroughly to prevent fire accidents.
