This study tried to reveal pattern of change in climatic normals during 1981-2010 and 1991-2020 from 28 weather stations in South Korea as well as its relationships with land cover change. Most of the weather stations showed temperature increase during 1991-2020 compared to 1981-2010, and positive correlations were found between temperature and urbanization in land cover, with the highest correlation coefficient in min. temperature. Temperature data also showed negative correlations with suburbanization in land cover, with lower correlation coefficients than urbanization in land cover. Overall decreases in relative humidity were revealed from the weather stations. However, clear relationships between relative humidity and land cover were not found in this study. The other climate data such as precipitation, sunshine and mean wind speed showed various ratios of change depending on the weather stations, without certain relationships with land cover.
