I think it's really strange that it's a seasonal flow. If I try to remember last summer's heat, is it me that I do not remember well? The temperature is over 40 ° C, so the place where I recorded the best heat in the observation day is correct.

The attire of the street is a thick coat, but some people dressed in winter coats. It's because of the sudden temperature. In just one day, the temperature fell by 5 degrees Celsius, and the cold wind pounded into my clothes.

Today 's (11th) morning The lowest temperature in Seoul recorded 6.1 ℃. It is about 5 ℃ lower than the lowest temperature recorded 11.6 ℃ yesterday. The sensation temperature was further reduced by 2 ° C. The average annual average of 30 years from 1981 to 2010 is 12.2 ℃, which is about 6 ℃ lower than this time.

Temperatures at the top of the high mountain were mostly down to zero. Like winter. The temperature of Mt. Seolak dropped to -4.1 ℃ and the first ice frozen in Mt. The Daegwallyeong Gion also recorded -1.0 degrees Celsius, which is 12 days later than last year.
Suddenly the reason for the cold weather is the cold air from the north. The continental highway, which occupies a large area from Mongolia to China, is the result of expanding forces to the Korean peninsula. This air is as strong as the hot air of the North Pacific high pressure that drives the summer heat wave.

Because of this, until Friday morning and Saturday morning, the temperature is likely to fall by more than 1,2 degrees Celsius due to the effects of the cold continental high pressure. It is because of the clear weather that radiative cooling is getting worse and the heat of the ground gets out a lot. However, the wind seems to gradually weaken, and the coldness felt by the body seems to be the worst on Friday morning.

However, it is not yet time for the continental high pressure to raise the force. It is now mid-October. The daytime temperature is still high, so it feels a lot different from the winter cold. Gion starts to climb from the weekend afternoon, and it is expected to regain the temperature at this time of the year from Sunday afternoon.

I wonder, but when will Seoul's temperature drop to minus? Maybe this time you will feel the winter cold, can you experience this cold in October?

Since 1973, when I looked at the lowest temperature in Seoul, I expected a certain amount. The temperature on the Korean peninsula has been rising rapidly, but it was often seen that temperatures dropped below zero in October before 2002, but the temperature has not dropped below minus 2003 since 2003.

The earliest cold weather came in 1982 and on October 24 the temperature was -0.1 ℃, and on the next day, 25 ℃, the temperature went down to -1.1 ℃. The lowest temperature in October was 1997, and the temperature was -2.0 ℃ on the 31st.

Autumn is very different from spring to the weather. Especially because the wind does not blow up like a spring, it is a great place to go out if the temperature is reasonable. If there is a clear plan for the weekend that we have delayed because of the typhoon as the weather is clear and the temperature is expected to rise gradually, it would be better to move on this weekend.

However, those who plan to come to the mountains, please note that temperatures can go down to minus, and that temperatures rise much during lunch, and you should be careful about temperature control. Everyone is eager to enjoy the happy autumn.
