On the afternoon of Monday, the 21st, very strong showers will fall across the country. On the 22nd and 24th, ‘heavy rain warning’ level precipitation may fall. Even after the rain, the heat will continue without stopping.
The Korea Meteorological Administration predicted on the 20th, “From 12:00 noon to 9:00 pm on the 21st, there will be places where showers come in the metropolitan area, inland and mountainous areas of Gangwon, Chungcheong, Jeolla, inland Gyeongbuk, inland northwest Gyeongsangnam-do, and Jeju.” According to the short-term forecast of the Korea Meteorological Administration, showers may fall in most of the metropolitan area, Yeongseo in Gangwon, and inland areas in Chungcheong from 5:00 to 7:00 pm on the 21st, which is the time of work. However, shower forecasts are highly uncertain and may change over time. You should keep checking the latest forecast from the National Weather Service.
Rainfall on the 21st is expected to be 5 to 60 mm in Seoul, Gyeonggi, Gangwon inland and mountainous areas, Sejong and northern Chungcheong, and 5 to 40 mm in Daejeon and Chungcheong southern areas, Gwangju and Jeolla, Gyeongbuk inland and Gyeongnam northwest inland, and Jeju. There may be places with very strong showers of 30 to 60 mm per hour.
From the 22nd to the 24th, there may be heavy rain
The Korea Meteorological Administration announced in a regular briefing on the 20th, “There is a possibility of announcing a heavy rain warning on the 22nd and 24th.” A heavy rain advisory is issued when more than 60mm of rainfall is expected for three hours or more than 110mm of rainfall is expected for 12 hours.
By 9:00 am on the 20th, the North Pacific high pressure has expanded to the Korean Peninsula, and cold, dry air from the north is present in the northern part of the Korean Peninsula. On the 22nd, cold and dry air from the north will move south to the Korean Peninsula, and as pressure troughs and low pressure develop at the border with the North Pacific high pressure, it will rain across the country until the 24th.
On the 22nd and 23rd, rain will be concentrated especially in the metropolitan area. This is because hot and humid southwest winds intensify in front of the pressure trough passing through the north. On the 23rd and 24th, strong and heavy rain may fall across the country. Depending on the speed of movement of the low pressure, there is a possibility that it will continue메이저사이트 until the 25th with rain.
Heavy rainfall is also expected in North Korea. Choi Jeong-hee, a forecast analyst at the Korea Meteorological Administration, said, “In the case of the border area with North Korea, special attention should be paid to the possibility of river flooding.”
It is difficult to view this precipitation as a ‘second rainy season’. The Korea Meteorological Administration defined the second rainy season as “the period when the average precipitation over 5 days exceeds 7 mm” in the “2022 Rainy Season White Paper” published last year. In addition, during the second rainy season, the North Pacific high pressure contracts, and as in the rainy season, it is often affected by ‘frontal precipitation’, which causes rain to rise and fall in a narrow precipitation belt, but this precipitation is affected by low pressure.
The hot weather will continue. Forecast analyst Choi said, “Even after the rain stops, it seems that it will be affected by the North Pacific high pressure.”
