THE country has issued its first-ever emergency heatwave alert under a new warning system launched this year, advising people to halt outdoor activities and keep cool.
The new warning system was introduced yesterday to better deal with a rising number of heatwaves in South Korea, which have become longer and more intense, officials said.
An emergency alert is issued when areas experiencing a heatwave are forecast to hit perceived temperatures of 38°C or an actual temperature of 39°C for one day.
“The Korea Meteorological Administration issued an Emergency Heatwave Warning at 10am local time (yesterday) for two cities in southern North Gyeongsang Province – Gyeongsan and Pohang,” said chief Lee Mi-seon at a press briefing.
“This marks the first time it has been issued since the system took effect,” she added.
The affected areas saw temperatures reach the emergency criteria over the weekend.
“An emergency heatwave warning does not simply mean the weather is extremely hot,” Lee said. “It indicates conditions in which even healthy people face a significantly elevated risk of serious harm, including heat-related illness and death.”
People engaged in outdoor activities should stop immediately and move to a cool place, and no one, including children or pets, should be left inside a vehicle, she added.
KMA data shows 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.
The average annual number of tropical nights has also jumped from four to 14 over the same period.
A heatwave day is defined as one with a maximum temperature of at least 33°C, while a tropical night is one when the overnight low remains at 25°C or above.
The new system comes as Europe endures a scorching summer after a June heatwave shattered temperature records across the continent.
Oceans have experienced their hottest June on record and could set fresh highs in the months ahead, the European Union’s Copernicus Marine Service said this month.
Warmer oceans intensify tropical storms and add more moisture, which can fall as heavy rain.
Adding to the mix is this year’s return of El Nino, a natural climate phenomenon that warms Pacific Ocean surface temperatures and typically occurs every two to seven years. — AFP
