Abstract: In this study, the impact of climate change on the characteristics of evapotranspiration in Korea was assessed.The Regional Concentration Pathway (RCP) 4.5 and 8.5 scenarios were used to calculate the reference evapotranspiration for 62 stations of the Korea Meteorological Administration (KMA) and compared with the calculation results from observation data.The results of the analysis showed that the average annual evapotranspiration increases by 5.4% in the RCP 4.5 scenario and 9.5% in the RCP 8.5 scenario compared with the current one.On a monthly scale, the reference evapotranspiration for January, February, November and December is expected to increase by more than 10% compared to the current period.The ratio of annual rainfall to yearly evapotranspiration was used to examine the possibility of droughts for future periods, and the results were found to be relatively high in the RCP 8.5 scenario when compared to the RCP 4.5 scenario.The increase in the reference evapotranspiration due to climate change may lead to a decrease in the available water resources, and therefore, continuous monitoring and appropriate adaptation measures are necessary.
