1000-Year Quasi-Periodicity of Weak Monsoon Events in Temperate Northeast Asia since the Mid-Holocene

Abstract: The Holocene variability in the East Asian summer monsoon (EASM) based on speleothem δ18O records has inconsistencies in timing, duration, and expression of millennial-scale events among nearby regions, and even within the same cave. Here, we present another stalagmite δ18O record with multi-decadal time resolution from the temperate Korean Peninsula (KP) for the last 5500 years in order to compare with Holocene millennial-scale EASM events from Southeast Asia. Based on our new stalagmite δ18O record, millenni… Show more

“…Therefore, the KP is much closer to the EASM rainband than is northeast China, so the KP is highly affected by rainfall forcing of the EASM rainband. In comparison with BN-1 9 of South Korea, δ 18 O of HC 33 for southeastern China had small values, but a higher amplitude ( Fig. 4c, d), indicating greater rainfall intensity in southeastern China due to its location within the EASM rainband area (Fig.…”
