Historic Heat Dome Grips Korean Peninsula, Threatening Record Temperatures
A dangerous and potentially historic heat wave is forecast to engulf the Korean Peninsula this weekend, with temperatures expected to soar to 38 degrees Celsius (100 degrees Fahrenheit) in western regions, including Seoul. Authorities are urging residents to take precautions against the extreme heat, which is being driven by a rare confluence of atmospheric conditions.
The approaching heat wave is shaping up to be the strongest of the summer, according to reports from Yonhap News TV. Data indicates that temperatures reaching 38 degrees Celsius in Seoul during late July have only occurred in two previous years – 1994 and 2018 – both of which experienced exceptionally severe heat waves.
‘Heat Dome’ Traps Region in Sweltering Conditions
The extreme temperatures are attributed to a persistent high-pressure system that has settled over the Korean Peninsula. Currently, both the North Pacific and Tibetan high-pressure systems are overlapping, effectively trapping the region within a “heat dome,” as described by one analyst. This configuration prevents cooler air from circulating and intensifies the heat.
Adding to the intensity, southeastern winds originating from tropical storms south of the peninsula are expected to further elevate temperatures, particularly in the midwestern areas, including Seoul. “The North Pacific High Pressure and Tibet High Pressure are influenced at the same time, with strong sunlight and southeast winds in the clear weather, and the highest daytime temperatures in the west area will rise more than 38 degrees,” a senior official stated.
‘Tropical Nights’ Expected as Humidity Amplifies Heat
The high levels of water vapor in the atmosphere will exacerbate the heat, leading to what are being called “tropical nights” – evenings where temperatures remain uncomfortably high. These conditions will likely persist throughout the weekend. While temperatures are expected to decrease slightly next week, they will remain elevated, hovering around 35 degrees Celsius (95 degrees Fahrenheit).
The Korea Meteorological Agency is advising citizens to limit outdoor activities and stay hydrated to mitigate the health risks associated with prolonged exposure to extreme heat. The agency emphasized the importance of preventative measures to protect against heat-related illnesses both during the day and night.
