Jeju – Today’s rain sometimes… The heat wave and tropical nights continue

According to the Jeju Regional Meteorological Administration, it will occasionally rain in Jeju, mainly in the mountainous regions, in the south, and in the eastern part due to the influence of a cyclone moving slowly in the Shandong Peninsula of China.

Estimated precipitation is 20-60 mm until the 8th, and more than 100 mm of rain will fall in many places such as mountains.

The maximum temperature during the day will be 28-33 degrees, similar to the day before (27-33 degrees).

This rain will expand to the area before the dawn of the 8th and will continue until the 9th.

Even if it rains, the heat is not expected to cool.

The Korea Meteorological Administration said, “While the heat wave warning is in effect in the north, east, and west of Jeju Island, the temperature during the day will rise to around 33 degrees celsius, and the humidity will be higher than this.”

Even last night, a tropical night occurred in Jeju.

The Korea Meteorological Administration has the lowest temperature for each area of the island from 6 p.m. to 9 p.m. on the previous day, at 27.8 degrees in Jeju (North), 26.3 degrees in Seogwipo (South), 25.9 degrees in Gosan (West), and 26.8 degrees in Seongsan (East).

Sunrise – Sunset – Fine Dust – UV Levels

Sunrise: 05:51 | Sunset: 19:28

The PM 2.5 micro fine dust level is BAD to VERY BAD (07:00 KST)

The PM 10 fine dust level is BAD (07:00 KST)

2020-08-07 NOTE: For the last few days there has been a noted air quality data difference between Jeju’s local fine dust station maps and national maps. This difference could be due to a volcanic eruption off the coast of Japan and the effect on Jeju.

The UV level is HIGH (early morning) / NORMAL (morning) / NORMAL (afternoon)

Please refer to the Jeju Environment Protection Research Center for the local fine dust situation (http://air.jeju.go.kr/index.htm)

Air Korea (https://bit.ly/2taWZp5) has excellent maps showing the real-time influence of fine dust across the whole country.

Sleepless Jeju, the ‘hottest night’ in 97 years

As the hot weather continues in the Jeju area, the night from the 5th to the 6th was recorded as the hottest night ever.

According to the Jeju Regional Meteorological Administration on the 6th, the lowest temperature in the northern part of Jeju City was 29.7 degrees from 6 pm on the 5th of the previous day to 9 am on the next day.

This is the highest nightly minimum temperature since 1923 when meteorological observation began. The temperature has never been this high at night since 1973, when tropical night data was accumulated.

Tropical night means the phenomenon that the minimum temperature does not drop below 25 degrees during the night. It is usually used as an indicator of heat because it is difficult to fall asleep when the temperature does not drop below 25 degrees.

In the northern part of Jeju, tropical nights have continued for ten days since the night of the 27th of last month. The same goes for other areas with 6 consecutive nights in Seogwipo, 8 in Gosan, and 6 Seongsan, tropical nights occurred.

The Korea Meteorological Administration explained that the high temperature and humidity of the south wind flowed to the edge of the North Pacific High Pressure, and the temperature that had been heated during the day did not drop sufficiently at night, causing a tropical night.

It was also analyzed that the ‘fohn phenomenon’, in which the humid air goes over the mountain area and becomes hot and dry, also stimulated the tropical field. The high temperature and high humidity of the air that has flown over the Halla Mountain has heated the northern region.

Currently, heatwave warning is in effect throughout Jeju except Chujado and the mountain area.

There will be rainy areas around the mountains and the south, and there will be places where thunder and lightning strike with gusts, but the highest temperature in the daytime will exceed 33 degrees and the heat will not go.
