MOTIVATION
Due to the intensifying impacts of global climate change, the seasonal patterns that have long defined life in South Korea are now undergoing noticeable shifts. In particular, the summer season is gradually expanding, and the traditional boundaries between spring, summer, autumn, and winter are becoming increasingly blurred. This change is not only something we feel in our daily lives but is also clearly reflected in meteorological data.
The year 2024 stands out as a turning point in this ongoing trend. A strong El Niño event amplified global warming effects, making 2024 one of the hottest years ever recorded worldwide. South Korea was no exception. Beginning in early April, temperatures across the country consistently exceeded historical averages, and by mid-April, summer-like heat was already being recorded in many regions. These unusually high temperatures marked a significant shift in the seasonal timeline, pushing the perceived start of summer several weeks earlier than usual.
In response to this phenomenon, our project focuses on a five-day period from April 11 to April 15, 2024. By analyzing detailed weather data during this key time window, we aim to understand how much earlier the summer season is beginning, how much longer it may continue in the future, and how much more intense the heat might become. Through this analysis, we seek to identify concrete trends in Korea’s changing climate and offer data-driven insights into the progression of seasonal shifts.
Beyond the scientific analysis, our study also considers the broader implications of extended and intensified summers. These changes may impact multiple aspects of society, including public health, energy consumption, agriculture, and urban living. Therefore, we also aim to highlight the growing need for adaptation strategies that can help communities and policymakers prepare for a hotter and more unpredictable climate.
Ultimately, the goal of this research is to provide a clearer understanding of how climate change is reshaping Korea’s seasonal structure and to propose practical measures that will support climate resilience and long-term adaptation.
