On the morning of the 21st, the city center was covered in mist, as seen from the Bugak Skyway in Jongno-gu, Seoul. Yunhap news
On the morning of the 21st, on the way to work, the atmosphere in the city center was covered in pale colors. Clouds, mist, and fine dust cover the sky. The Meteorological Administration said on the day that “the entire country will be cloudy all day and moderate rains will fall sequentially from the southern regions.”
The biggest cause of the cloudy sky is the wide band of clouds that covered Korea. A long, broad cloud continued along the pressure valley that developed between the high pressure located in northern Japan’s waters and the low pressure located in northern China, covering most of Korea.
‘Rain cloud band’ between high high pressure and large low pressure
On the morning of the 21st, the cloud belt covering the Korean Peninsula was wide. Rain clouds are expected to move gradually eastward and rain from the afternoon of the 21st. Meteorological Materials Agency
This band of clouds, which is currently raining on the east coast of China, is gradually moving east towards Korea. The Meteorological Administration explained: “The rain cloud is approaching from the East China Sea towards the East China Sea and the West Sea and the South Sea of Jeju Island at a speed of 80 km / h.” “Starting from Jeju in the morning, it will start to rain on the south coast of Jeollanam-do in the afternoon.”
Since the afternoon of the 21st, it begins to rain in the southern regions and Jeju Island, and it rains since night in the south of Chungcheong province and in the north of Gyeonggi province. In Seoul, Gyeonggi, and Gangwon-do, Yeongseobuk-do is expected to rain soon in the early hours of the 22nd, as the river water passes quickly. By the morning of the 22nd, there is expected to be less than 0-40mm of rain in Jeju and the south coast, 5-10mm in the south region and 5mm in the central region.

The fog generated in the daily great crossing did not disperse due to atmospheric congestion, which made the view more cloudy at dawn. The Meteorological Administration said: “There is thick fog with a visible distance of about 200 meters on the west coast of Gyeonggi Province, Chungcheong-do, inland from North Gyeongbuk, inland from Jeonnam and inland from Gyeongnam, and there are foggy places with less than 1 km visibility in other inland areas. You have to be careful. ”

National ultrafine dust concentration data at 10 am on the 21st. Most of the western regions, centered on the west coast of Chungcheongnam-do, showed a concentration of “bad”. Materials National Institute of Environmental Sciences
Fine dust also clouded the sky. The Integrated Air Quality Forecast Center of the National Environment Corporation explained that “the day before there was fine dust and fine domestic dust was added, and the concentration of fine dust in the morning will be high in some regions of the Midwest. “. The air congestion and fine dust that has continued since the 19th are somewhat resolved by the rain and wind on the 21st, but the concentration of fine dust in the central region on the 22nd has increased as the yellow dust from the Gobi desert and China’s Inner Mongolia entered on the 20th. It appears to be higher. The Integrated Air Quality Forecasting Center added, “The concentration of domestic influences and affected areas may vary depending on the air flow.” If the wind starts to blow strongly due to the high pressure in the north from the 22nd day after the yellow dust passes, the atmospheric congestion is expected to resolve somewhat.
It’s cold … Friday morning experience in Seoul ‘one degree’
After the rain, cold air pushes in from the northwest. The minimum temperature on the morning of the 22nd is 7 ~ 15 degrees, and the minimum temperature on the morning of the 23rd falls to 0 ~ 11 degrees. In Seoul on the 23rd, the lowest morning temperature is expected to be 5 degrees, and the temperature drops to 1 ~ 2 degrees as the wind increases. There is a possibility of snow in the Gangwon Mountains, and the morning lows in the central and southern mountains are expected to drop to sub-zero temperatures. He sat
The Meteorological Administration said: “Except in some coastal areas, the cold will drop to about 5 degrees Celsius for a while,” he said. “You have to be careful with crop damage.”
