The increased frequency of drought and flood due to climate change was a global problem. In particular, drought was
recognized as a serious environmental, ecological, social, and economic disaster. Therefore, it is necessary to study the
measures to prevent it. In this study, we will estimate the meteorological drought index in the Han River Basin and analyze
the impact of climate change on drought. The change of the meteorological drought occurrence due to climate change
in the Han River separated by the common drought and severe drought was analyzed using the Representative Concentration
Pathways (RCPs) scenarios provided by the Intergovernmental Panel on Climate Change (IPCC). The years 1973 - 2010
were selected for analysis in the current period. Using the scenario, we separated the future period (TargetⅠ: 2011 - 2039,
TargetⅡ: 2040 - 2069, TargetⅢ : 2070 – 2099). The number of occurrences of less than -1.0 and -1.5 standard
precipitation index were analyzed by SPI 3, 6, 12. Looking at the results, trends in rainfall in the Han River was expected
to increase from the current figures, the occurrence of drought is predicted to decline in the future. However, the number
of drought occurrence was analyzed to increase toward long-term drought. The number of severe drought occurrences
was usually larger than the common drought estimated. Additional studies may be considered in addition to the agricultural
drought, hydrological drought, socio-economic drought. This will be done by using efficient water management. The
results can be used as a basis for future drought analysis of the Han River.
