In September this year, last month was exceptionally hot and there was a lot of heavy rain, so I couldn't feel autumn.

In fact, it was analyzed that it was the hottest and the most precipitated September ever,

I'll connect you to our reporters for more information. Reporter Jung Hyeyoon!

The Korea Meteorological Administration released climate analysis data in September this year?

[Journalist]
Yes, that's right.

The Korea Meteorological Administration released a detailed analysis of the weather in September, which was unusually volatile.

First of all, September this year was recorded as the hottest month ever, with an average national temperature of 24.7 degrees, 4.2 degrees higher than the average year (20.5 degrees),

The number of heat waves and tropical nights has been the highest since observation.

The number of heatwave days was six days, more than the average (0.2 days), and the number of tropical nights was 4.3 days, four times the average (0.1 days).

Both the number of days of heat and tropical nights are the number one in history.

In particular, the first heat wave occurred in September for the first time since observation at seven locations, including Seoul, Seosan, Ganghwa, Icheon, Boeun, Gosan, and Jangsu,
The first tropical nights in September were also recorded in four areas: Chuncheon, Yangpyeong, Geumsan, and Imsil,
.

In particular, the number of tropical nights per year until September was 24.5 days, nearly four times the average (6.6 days), the highest ever.

After the heat wave, there was a heavy fall rain, and this amount of rain was a record?

[Reporter]
Yes, the autumn rain that came after the heat wave was also record.

The average precipitation across the country in September was 241 mm, 85.9 mm more than the average of 155.1 mm, the Korea Meteorological Administration said.

This is about 54.6% more than the average precipitation.

In particular, between September 20 and 21, a lot of rain was concentrated
The accumulated precipitation in the two days of
was 529.4mm in Changwon, 403.4mm in Busan, and 381.2mm in Geoje.

In particular, some areas, including Seosan, Changwon, and Busan, broke the record for the highest number of precipitation on September, with the amount of rain falling between 200 and 400 millimeters per day.

Jindo and Changwon recorded more than 100mm of precipitation in an hour, reminiscent of a midsummer downpour.

The Korea Meteorological Administration said that after the Chuseok heatwave, a stagnant front was formed and heavy rain fell in the form of an autumn monsoon, and an unusual downpour was added to the effect of the tropical low pressure region moving north to the Korean Peninsula.

In particular, Tibet's high pressure expanded to the upper layers of the Korean Peninsula in September this year, and the North Pacific's high pressure strengthened to the south, leading to unusual heat and heavy rains as a large amount of hot and humid air flowed along its edge.

The Korea Meteorological Administration said in September this year that average sea surface temperatures around the Korean Peninsula have remained at their highest levels in the last decade, and that we need to monitor and respond more closely to summer disasters that are prolonged by climate change.
