(Seoul = Yonhap News) Reporter Lee Jae-young = From Monday, the 28th to the 29th, a record amount of rain for rain falling in late November will fall across the country, centering on the central region.
After the rain, it is expected that the cold will come.
According to the Korea Meteorological Administration on the 27th, as the whirlpool around the North Pole has recently turned to a weaker state (negative Arctic Oscillation), East Asia has also become colder due to the influence of cold air from the north moving south. The lowest temperature in Seoul on this day was minus 1.1 degrees Celsius, the first time this fall.
In Cheorwon-gun (Gimhwa), Gangwon-do, the lowest temperature went down to minus 8.5 degrees Celsius, and in Paju-si, Gyeonggi-do to -4.9 degrees Celsius.
The negative Arctic Oscillation that caused the cold that day is expected to continue until early next month.
From the 28th, relatively warm and humid air descends from an altitude of 3 km, and cold air descends behind it, developing low pressure and pouring heavy rain across the country.
Rain will start in Jeju at dawn on the 28th, spread to the central region, Honam, and western Gyeongsang in the morning, and then fall across the country in the evening.
This rain is expected to continue until the morning of the 29th, and the amount of precipitation is 20 to 80 mm in the metropolitan area, Gangwon Yeongseo, Chungcheong, Jeonnam eastern southern coast, Gyeongnam southern coast, Jeju, around Mt. It is expected to be 50 mm.
In particular, it may rain more than 120 mm in the mountainous areas of Jeju where the topography is affected.
Precipitation is expected to be concentrated in the central region this time.
Numerical forecasting models also differed in their forecasts regarding the amount of precipitation in areas other than the central region, but they predicted the same thing that the area with concentrated rain would be the central region.
The Korea Meteorological Administration warned that this rain might be record-heavy for rain in late November.
In the case of Seoul, the highest amount of precipitation in late November so far was 60.3mm on November 29, 1982, and an amount exceeding this might be poured.
After the rain stops, the cold continental high pressure will expand and it will get cold from the followingnoon of the 29th, followed by a cold wave.
Unlike this weekend, the upper atmosphere is also dominated by cold air, and the cold continental high pressure expands its influence on the ground, so the cold will be strong and last for a long time.
In particular, the temperature will drop rapidly. On the morning of the 29th, most of the areas where the morning temperature exceeds 10 degrees Celsius, but on the morning of the 30th, the temperature in the western part of the central region will drop to minus 5 degrees, and some parts of the southern part will record below zero.
On the 1st of next month, the morning temperature in the northern part of the central region will drop to minus 10 degrees.
As the temperature drops significantly, a cold wave warning may be issued throughout the country, including the metropolitan area, except for parts of the west and south coasts. ‘In case the minimum temperature in the morning drops by more than 15 degrees from the previous day’ is also a condition for issuing a cold wave warning.
As the temperature drops, the wind blows hard until the 1st, and the cold is expected to double.
When the continental high pressure expands, the cold wind passes over the relatively warm West Sea, creating a cloud belt due to the temperature difference between the sea level and the atmosphere. There is a possibility of snow in the west coast of Chungcheongnam-do.
However, the wind direction is not north-northwest and north-northwest, which blows from the west sea to the inland, so the snow cloud belt will not flow deep into the inland.
