On August 2023, researchers from Pohang University of Science and Technology examined how discrepancies between weather forecasts and actual conditions influenced public emotions during the landfall of Typhoon Khanun. The study highlights the emotional responses triggered by forecast errors, revealing significant differences in public sentiment in various regions of the Korean Peninsula.
Impact of Forecast Errors on Public Sentiment
Forecasts play a critical role in disaster preparedness, but inaccuracies can lead to heightened anxiety and confusion among the public. The research team, led by Professor Jonghun Kam and Kiru Kim, analyzed data from over 43,000 online posts and assessed the prediction accuracy of the Korean Meteorological Administration. They noted that areas with overestimated rainfall exhibited emotions such as anxiety and worry, while those with underestimated rainfall experienced confusion and sadness.
Regional Emotional Responses During Typhoon Khanun
The study identified distinct emotional patterns across different regions. In the eastern and southeastern areas, where actual rainfall exceeded forecasts, discussions were rife with confusion and uncertainty. Conversely, in the western and metropolitan regions, where forecasts were overly optimistic, emotions of worry transitioned to relief as the storm passed. Approximately 55% of online discourse registered negative sentiments, with anxiety being the most prevalent emotional response.
