Abstract

In this study, standard precipitation index- based analysis associated with run theory was performed using 53 years' (1967-2019) precipitation data to investigate the meteorological drought in Chuncheon. The duration of the meteorological drought in Chuncheon was 8.06 months, magnitude of the drought was -8.21, and average drought depth was -1.08. The drought in May 2014 lasted 21 months until January 2016; the drought scale and average depth was -34.06 and -1.62, respectively. This was the most severe drought in Chuncheon. As a result of drought frequency analysis, the drought scale of May to December in 2014 was estimated to be -16.16, and the return period was estimated to be 300 years. These results are expected to further increase the magnitude and frequency of weather droughts caused by climate change. Therefore, it is critical to prepare appropriate structural measures.
