“…Numerous geological records have preserved the EAWM's variations at orbital timescales, including the Chinese loess records that indicated a dominant EAWM period of 100 kyr (Ding et al, ; Lu et al, ; Sun et al, ). Meanwhile, marine sediments in the South China Sea suggest that the EAWM has a significant period of 23 kyr (Yamamoto et al, ; Yu et al, ). Our modeling study helps to explain the discrepancies of these dominant periods between the northern and southern geological records.…”

“…Marine sediments from the Sea of Japan also suggest that EAWM′s variations follow glacial‐interglacial cycles (Gallagher et al, ). However, some marine sediments in the South China Sea demonstrate that the EAWM (as inferred from a sea surface temperature gradient index) has a significant period of 23 kyr, which arises from Northern Hemisphere winter insolation (NHWI) variations; the EAWM is stronger when the NHWI is lower (Yamamoto et al, ; Yu et al, ). The discrepancies among proxy records have generated arguments over which forcing mechanism (global ice‐sheet volume versus orbital insolation) dominates the orbital‐scale variations of the EAWM.…”

Transient simulations for the last 300,000 years are conducted to identify how orbital insolation, greenhouse gases, and ice sheets affect variations of the East Asia winter monsoon (EAWM). Results show that the southern EAWM's dominant period is 23 kyr in response to variations in boreal winter insolation (primarily from precession), while the northern EAWM's dominant period is 100 kyr and is most strongly modulated by Northern Hemisphere ice sheets, displaying a significant latitude dependence in orbital‐scale EAWM variations. The precession‐modulated boreal winter insolation can control the southern EAWM by influencing zonal land‐sea thermal contrast at low latitudes, while Northern Hemisphere ice sheets during glacial periods can strengthen the northern EAWM by forcing a powerful cyclonic circulation anomaly over northern Pacific. The different responses of southern and northern EAWM to orbital insolation and ice‐sheet forcings can further lead to in phase or out phase variations between the southern and northern EAWM.

“…3A). This record shows East Asian Monsoon activity which is dynamically linked to the African Monsoon system (Yamamoto et al, 2013). Depleted δ 18 O values of the Sanbao-Hulu record have been related to maximum intensity of the African monsoon coinciding with an increase in precipitation and river run off over the Eastern Mediterranean Sea (Fig.…”

New insights into upper MOW variability over the last 150kyr from IODP 339 Site U1386 in the Gulf of Cadiz

a b s t r a c tThe upper Mediterranean Outflow Water (MOW) paleo-oceanographic history in the Gulf of Cadiz is poorly constrained due to the lack of high-resolution records that pre-date the last glaciation. Existing proxy records concentrate on MOW variability along the middle slope of the Gulf of Cadiz. Here we present a continuous high-resolution benthic foraminifera δ 18 O record from the upper MOW core at IODP Expedition 339 Site U1386 in the Gulf of Cadiz of the past 150,000 years. Based on δ 18 O, grain-size and Zr/Al variability comparison of our results with existing Mediterranean Sea (MD01-2472, MD95-2043), open ocean (LR04) and Gulf of Cadiz (MD99-2339) records we have gathered new insights into the evolution of the upper MOW core on glacial-interglacial timescales. The influence of the upper MOW at Site U1386 was strongest during MIS 5 and MIS 1. Similar δ 18 O variability can be seen in the Levantine Intermediate Water (LIW) originating from the Levantine Basin of the Eastern Mediterranean Sea. We found clear indication for a vertical shift of the MOW from the upper to the middle slope of the Gulf of Cadiz during sea level lowstands coinciding with MIS 4 and MIS 2 but also during MIS 3. Additionally, our results indicate an increased upper MOW flow correlated with Heinrich Events 7 to 10 and the Younger Dryas, and also inversely relate to precession-forced monsoonal freshwater inputs into the Eastern Mediterranean. In the context of Sapropel formation, we could not find conclusive evidence of the proposed MOW shutdown in our data.

“…On the interdecadal to decadal time scale, meteorological observations indicate a significant correlation between ENSO and EAWM (He & Wang, ; Kim et al, ; Wang et al, ). Much effort has been made to understand the long‐term variability of the EASM using records from loess‐paleosol sequences (e.g., Ding et al, ; Sun et al, ; Xiao et al, ), lacustrine sediments (e.g., Liu et al, ; Wang et al, ), stalagmites (Sone et al, ), and marine sediments (e.g., Huang et al, ; Steinke et al, ; Yamamoto et al, ). On longer time scales, however, only a few studies have examined possible links between ENSO and the EAWM based on climate model simulations and sediment records from low latitude regions (An et al, ; Xu et al, ; Zheng et al, ).…”

Instrumental records indicate a close relationship between the El Niño‐Southern Oscillation and the East Asian winter monsoon (EAWM) on interannual to decadal time scales. However, few studies have examined possible links between them on centennial/millennial time scales. In Northeast China, modern observations show that the immigration of temperate forest trees such as Pinus (pine) and Quercus (oak) into cold temperate boreal forest is sensitive to changes in winter temperature. Here we present a continuous high‐resolution pollen record from Lake Moon in the central part of the Great Khingan Mountain Range, Northeast China. The record reveals increasing contents of Pinus and Quercus pollen after ~6.0 ka cal. BP, which may indicate a gradual weakening of the EAWM. It is broadly coupled with an increasing El Niño frequency since the middle Holocene, and we observe a statistically significant correlation between the percentages of Pinus and Quercus and a time series of El Niño events. On the centennial to millennial time scale, the results of wavelet analysis and band‐pass filtering show that the occurrence and development of El Niño have also promoted a weaker EAWM after ~6.0 ka cal. BP, which is inversely correlated with the variation of the ca. 500‐year cycle originated from changes in solar output. These results imply that the climate transition in the mid‐Holocene is caused by the change of variations in solar activity and amplified by ocean circulation El Niño‐Southern Oscillation to influence the East Asian Monsoon system, especially the EAWM, and finally change the vegetation in Great Khingan Mountain Range.
