In this study, we classified 219 representative weather stations in the Republic of Korea based on geographical features such as altitude, distance from the coastal line, total population, population density, and urban-related land cover ratios, and analyzed climate characteristics by the classified categories. The representative weather stations were categorized into six groups: mountain, plain inland city, plain inland rural, coastal city, and coastal rural stations. The most prevalent group was plain inland rural stations with 41.6%, followed by plain inland city ones with 22.8%, coastal rural ones with 21.9%, coastal city ones with 9.1%, and mountain ones with 4.6%. The climate characteristics among these geographical groups revealed significant differences (α=0.05) for annual average temperature except for coastal city and coastal rural group. However, annual precipitation was only significantly different between plain inland city and plain inland rural ones, and between coastal city and plain inland rural ones. The analyses of hot extreme climates revealed distinct differences among the six groups. At plain inland city ones, heat wave days were notably greater (15.8 days) than mountain ones (3.3 days), indicating the effect of city and elevation. Conversely, cold wave days were significantly much more in mountain stations (18.3 days) than coastal rural (1.5 days) and city (1.3 days) groups largely due to the modulation of warmer oceans in winter, elevation and city. The results of this study might be used for basic information for establishing future climate change adaptation strategies in the Republic of Korea.
Abstract
In this study, we classified 219 representative weather stations in the Republic of Korea based on geographical features such as altitude, distance from the coastal line, total population, population density, and urban-related land cover ratios, and analyzed climate characteristics by the classified categories. The representative weather stations were categorized into six groups: mountain, plain inland city, plain inland rural, coastal city, and coastal rural stations. The most prevalent group was plain inland rural stations with 41.6%, followed by plain inland city ones with 22.8%, coastal rural ones with 21.9%, coastal city ones with 9.1%, and mountain ones with 4.6%. The climate characteristics among these geographical groups revealed significant differences (α=0.05) for annual average temperature except for coastal city and coastal rural group. However, annual precipitation was only significantly different between plain inland city and plain inland rural ones, and between coastal city and plain inland rural ones. The analyses of hot extreme climates revealed distinct differences among the six groups. At plain inland city ones, heat wave days were notably greater (15.8 days) than mountain ones (3.3 days), indicating the effect of city and elevation. Conversely, cold wave days were significantly much more in mountain stations (18.3 days) than coastal rural (1.5 days) and city (1.3 days) groups largely due to the modulation of warmer oceans in winter, elevation and city. The results of this study might be used for basic information for establishing future climate change adaptation strategies in the Republic of Korea.
