South Korea recorded its highest temperature ever, with Yangsan reaching 42.5C amid a prolonged heatwave.
SEOUL: South Korea on Sunday registered its highest temperature since records began more than a century ago, according to the state weather agency.
The southeastern city of Yangsan saw the temperature reach 42.5C at 1:26 pm (0426 GMT), the Korea Meteorological Administration said on its website. Yangsan has been the epicentre of the ongoing heatwave, where temperatures exceeded 40C for a fifth consecutive day on Sunday.
Much of South Korea has been placed under heat warnings, with many cities seeing temperatures climb into the high 30s Celsius. More than 20 localities were under emergency heatwave alerts on Sunday, a new warning category introduced this year to better address rising temperatures.
An emergency alert is issued when areas experiencing a heatwave are forecast to hit perceived temperatures of 38C or an actual temperature of 39C for one day.
KMA data show the average annual number of heatwave days in the country has more than doubled to 19 over the past five years, from eight in the 1970s. A heatwave day is defined as one with a maximum temperature of at least 33C, while a tropical night is one when the overnight low remains 25C or above.
Scientists warn that extreme weather events such as heatwaves are becoming more frequent and intense as a result of climate change driven by human activity.
