초록

The purpose of this study is to quantify the magnitudes of projected 21st century temperature changes and shifting climate zones over Mt. Halla, Korea based on high-resolution (1km×1km) climate change scenario data sets down-scaled from a global climate model (HadGEM2-AO) simulations using PRIDE (PRISM based Downscaling Estimation Model) as well as the simulations of a Regional Climate Model (RCM; HadGEM3-RA). The high resolution climate data demonstrate that the magnitudes of increases in coldest and warmest monthly mean temperatures over Mt. Halla will exceed those of the averages across the Korean Peninsula during the 21st century, leading to the shifts of climate zones. The isoline with 5°C (20°C) of the coldest (warmest) monthly average temperature associated with sub-tropical (sub-alpine) climate zones will migrate from 100~230m (950~1,300m) to 300~500m (1,300~1,600m) of altitude in the late 21st century (2071~2100) under the RCP 4.5 scenario. These changes are expected to be more obviously observed in the south flank of Mt. Halla as well as under the RCP 8.5 scenario. These results indicate that changes in climate zones will lead to the extinction of sub-alpine ecosystems over Mt. Halla due to increases of summertime heat stress as well as to the expansion of the sub-tropical forest zone toward mid-mountain regions due to reduction of wintertime stress in the warmer 21st century.
