South Korea has lifted most heat-wave and tropical-night warnings after the high-pressure heat dome trapping the peninsula began to crack [1, 2].
The shift provides relief from weeks of extreme temperatures that strained public health and infrastructure, though the region now faces the dual challenge of lingering drought and approaching typhoons.
Cold air from the northeast entered the lower atmosphere, breaking the heat dome's hold on the region [1, 2]. This atmospheric change led to a significant reduction in extreme heat alerts across the country. In Daegu, heat-wave warnings were lifted after 21 days [1], while Busan saw its warnings end after 24 days [2].
In the capital, Seoul experienced two consecutive days without a tropical night [1]. Daytime temperatures in the city have remained below 35 °C [2]. Despite these improvements, the relief is partial, as temperatures across much of the country remain above 30 °C [1].
While the extreme heat is receding, the southern regions continue to struggle with a persistent drought caused by insufficient rainfall [1, 2]. Meteorologists are now monitoring the atmosphere for new variables. Specifically, upcoming typhoon cloud bands are forecast to be the primary influence on the weather in the coming days [1, 2].
Ban Ki-sung said via YTN the "double bombardment" that brought extreme heat to the country has disappeared, shifting focus toward the impact of typhoons [2].
“South Korea has lifted most heat-wave and tropical-night warnings after the high-pressure heat dome trapping the peninsula began to crack.”
The collapse of the heat dome marks a transition from a period of stagnant, extreme heat to a more volatile weather pattern. While the immediate threat of heat-stroke and energy grid strain from air conditioning may decrease, the focus now shifts to water security in the south and the potential for flooding or wind damage as typhoon systems approach the peninsula.
