Comparison of Simulated Precipitation Data in South Korea based on the GCM and RCM
Abstract
Nowadays, the management of hydro-infrastructures may face more challenging issues because of climate change. Especially, extreme rainfall events have been increased in frequency and intensity, and unexpected floods have affected a significant negative impact on society and the global economy. Therefore, a lot of studies are conducted to effectively address the climate change. In this study, extreme precipitation based on the regional climate model (RCM) and the global climate model (GCM) was extracted, and the performance of each model in reproducing precipitation patterns over South Korea was evaluated. Under two Shared Socioeconomic Pathways (SSPs; SSP2-4.5 and SSP5-8.5), the future changes are calculated for three time slices (2011-2040, 2041-2070, and 2071-2100) and compared to the reference period (1981-2010). GCM and RCM rainfall quantiles for the historical period and projections for the future period were quantitatively compared, and the variations in each model's output were spatially analyzed.
