What Are Impact-Based Forecasts?
- Impact-based forecasts are a more comprehensive approach to forecasting that utilizes scientific data to identify possible impacts that could vary by region and time, even under the same weather conditions.
- The Korea Meteorological Administration currently provides two types of impact-based forecasts: heatwaves and cold waves.
- Impact-based forecasts classify the risk level of weather conditions into four stages: Attention, Caution, Warning, and Danger. Corresponding response guidelines are provided based on the risk level.
Why Do We Need Impact-Based Forecasts?
- Severe weather conditions caused by climate change are rapidly increasing, resulting in escalated damage. Additionally, vulnerability to such disasters is being amplified due to complex industrial structures and societal transformations, including aging populations and densely populated areas.
Therefore, to effectively prevent and respond to these changes, we need detailed and specific information on weather impacts that goes beyond simple data on weather conditions.
What is the Difference Between Severe Weather Alerts and Impact-Based Forecasts?
- A severe weather alert is issued to warn about the potential occurrence of hazards caused by meteorological phenomena.
- On the other hand, impact-based forecasts go beyond mere hazard warnings by providing detailed information. They consider the regional level of vulnerability and exposure to hazards, offering socio-economic impacts specific to each region, as well as countermeasures to prevent potential damage.
