Heatwave in Korea: Persisting High Temperatures and Extreme Conditions

A scorching heatwave with record-high temperatures, due to two high-pressure systems, persists in Korea, leading to nationwide heatwave warnings.

### Record-High Temperatures in Gangneung and Sokcho
A scorching heatwave brought temperatures of over 30 degrees to Gangneung and Sokcho. The phenomenon of "super tropical nights" has been observed multiple times in Gangneung, with a record low temperature of 30.6 degrees. Sokcho also experienced a super tropical night, with the minimum temperature reaching 30.6 degrees Celsius.

### Record-Breaking Heatwave in South Korea
South Korea experienced its first extreme heat wave in Sokcho and Seoul in 2018, with record-low temperatures. Currently, the country is under a nationwide heatwave warning, except for certain regions, with Seoul being under a heat advisory. The high temperatures are attributed to a high-pressure system covering the Korean Peninsula, creating warm and dry conditions.

### The 2018 Heatwave and Current Weather Patterns in the Korean Peninsula
The Korean Peninsula experienced a record-breaking heatwave in 2018, with temperatures reaching as high as 41 degrees in Hongcheon. The heatwave was caused by the early and strong development of the North Pacific and Tibetan high-pressure systems, covering the peninsula and leading to an early end of the rainy season. Currently, the peninsula is facing record high temperatures and sea temperatures, with a later expansion period of the North Pacific High, making a stronger heatwave than 2018 less likely. Additionally, there is a new weather phenomenon of heavy rain showers, known as "needle rain," occurring in some areas.

### The Formation of Summer Rain Clouds in Korea
Summer rain in Korea is not caused by the Southeast Asia monsoon, but by the collision of warm air from the south and lingering cold air in the upper atmosphere, creating instability. This unique formation leads to the development of heavy rain clouds during the day. The rainy season in Korea is not over yet and is determined by the expansion of the North Pacific high pressure and the lifting of the stationary front.

### Uncertainty Over End of Rainy Season in North Korea
The rainy season may have ended near North Korea, but the Meteorological Administration is still evaluating the variables before making an official announcement. The administration plans to communicate its position in a briefing the following day.
