(a) Locations of the GG19-2–1 core site and other sites cited in the text: Hw12-A (Hwajinpo) and SOJ-2 (Songji) lakes, and BN-2 (Baeg-nyeong) cave, South Korea; SL (Silhailongwan) and JL (Jingpo) lakes, northeast China, and HE (Heshang) cave, central China; and MD81 in the western tropical Pacific. These maps were created using Generic Mapping Tools (v.5.4.4, https://www.generic-mapping-tools.org/download/). The dashed line indicates the northernmost extent of the Asian summer monsoon. Position and orientation of the rainband and westerly jet (WJ) stream during the Late Holocene are from Herzschuh et al.31 Arrowed grey parallel lines represent the general direction and width of the WJ stream. (b) Aerial photograph of Gonggeom-ji showing the ___location of the GG19-2–1 core site. (c) Seasonal changes (2002–2019 CE) in temperature and precipitation in the Sangju area, where the Gonggeom-ji paleo-reservoir is located, based on information from the Korea Meteorological Administration (https://data.kma.go.kr). (d) The study area belongs to the central temperate zone of the deciduous broadleaf forest based on the modern vegetation map of Korea (modified from Yim and Kira69) (drawn using CorelDRAW Graphics Suite X7). DBL F., deciduous broadleaved forest.
