Heavy Rain Nationwide from 22nd to 24th... 'Cheoseo's Magic' Unlikely to Appear

Rain is expected nationwide from the 22nd to the 24th. The magic of Cheoseo (處暑, the end of heat, on the 23rd), which marks the end of the heat and the arrival of fresh autumn, is not expected this year.

According to the Korea Meteorological Administration on the 20th, the North Pacific High, which had recently retreated toward Japan, is expanding its influence toward Korea starting this weekend.

As the North Pacific High expands its influence from the southeast of Korea, a trough connected to a northern low pressure system will pass through Northeast China from the 22nd, forming a long band of rain clouds behind it, bringing precipitation mainly to North Korea and the Seoul metropolitan area.

Southwesterly winds ahead of the trough will bring a large amount of moisture, resulting in considerable rainfall. Heavy rain is expected in the upper reaches of shared rivers such as the Imjin River and Hantan River, which may cause flooding downstream, so precautions are necessary.

After the rain caused by the trough, a low pressure system passing between the northern high pressure over Korea and the southeastern North Pacific High is expected to bring rain nationwide. This rain will continue on the 24th and possibly extend to the 25th.

Showers will continue mainly in the central region on the weekend and Monday, the 21st. Even after the rain stops, temperatures are expected to remain above average.

One of the causes of this rain is the inflow of warm and humid air from the south, so it will not significantly help lower the overall temperature. Additionally, after the low pressure system that brought the rain passes, the North Pacific High is expected to expand again and bring heat to Korea.
