Heat Wave Advisory Lifted
Overview
Lifting a heat wave advisory refers to the official procedure by which the Korea Meteorological Administration (KMA) determines that a previously issued heat wave advisory is no longer necessary. This indicates that the heat wave has ended or its intensity has weakened, reducing concerns for human life and property damage. It serves as an important signal for the public to resume daily life and economic activities.
Main Content
1. Lifting Criteria
A heat wave advisory is lifted when the following conditions are met:
- When the daily maximum apparent temperature is expected to remain below 33°C for two or more consecutive days.
- When the temperature within the heat wave advisory area has clearly dropped, eliminating concerns for additional damage.
- When meteorological conditions (e.g., strong winds, precipitation) are expected to naturally dissipate the heat wave.
2. Lifting Procedure
1. Weather Monitoring: The KMA analyzes data from the nationwide Automatic Weather Station (AWS) network and satellite data in real time.
2. Forecast Model Review: Numerical weather prediction models are used to forecast temperature, humidity, and wind speed for the next three days.
3. Regional Assessment: Decisions on lifting are made at the level of subdivided advisory zones by province or city.
4. Announcement and Dissemination: After an official announcement by the KMA, the information is immediately disseminated via emergency broadcast (CBS), television, internet, and social media.
3. Impacts When Lifted
- Daily Life: Recommendations to refrain from outdoor activities are lifted; air conditioner usage decreases; electricity demand stabilizes.
- Agriculture and Livestock: Advisories for crop and livestock management are lifted; safety measures for farmers are relaxed.
- Health: Emergency room visits for heat-related illnesses decrease; protective measures for vulnerable groups (elderly, children) are adjusted.
- Economy: Cooling costs are reduced; tourism and leisure industries are revitalized; construction site work resumes.
4. Precautions After Lifting
- Be prepared for the possibility of a sudden recurrence, as the heat wave may not be completely over.
- Avoid excessive physical activity while the body's thermoregulation ability remains weakened.
- Manage post-heat stress aftereffects for crops and livestock.
- Continue monitoring the reserve margin to ensure power grid stability.
Latest Trends
In 2024, the KMA refined the criteria for lifting heat wave advisories by simultaneously considering apparent temperature and duration. In 2025, a pilot system using artificial intelligence (AI)-based prediction models is being operated to forecast the lifting time up to six hours earlier. Additionally, as heat wave periods lengthen due to climate change, campaigns for 'post-heat wave aftereffect management' are being strengthened. More local governments are operating cooling shelters for an additional three days after the advisory is lifted. In metropolitan areas with severe urban heat island effects, monitoring of 'residual tropical nights'—where nighttime minimum temperatures remain high even after the advisory is lifted—is being intensified.
