“…The intensity of EAWM during the mid-Holocene has been reconstructed from different types of sediments in previous studies. A number of geologic records, including eolian sediments and peat deposits in northwestern China (An, 2000; Jia et al, 2015a; Li and Morrill, 2015; Liu et al, 2013; Yu et al, 2006; Zhao et al, 2016), biogeochemical evidence, fossil diatoms and pollen records in lake sediments from Huguang Maar Lake and Wuhu Lake in southeastern China (Jia et al, 2015b; Wang et al, 2008a, 2012; Zhang et al, 2016), and marine sediments from the eastern boundary of the East China Sea (Morimoto et al, 2007) and the western North Pacific (Huang et al, 2011; Sagawa et al, 2014; Tian et al, 2010), have all indicated a generally stronger-than-present EAWM intensity during the mid-Holocene. These were qualitatively accordant with results from the multiple PMIP models obtained from this study, as well as from previous equilibrium and transient simulations performed by the coupled model CCSM3 (Wen et al, 2016; Zhou and Zhao, 2009b).…”

The change in the East Asian winter (December–January–February) monsoon (EAWM) during the mid-Holocene, approximately 6000 years ago, was investigated using all available experiments within the Paleoclimate Modelling Intercomparison Project (PMIP). As defined by regional-averaged meridional wind speed at 850 hPa, the mid-Holocene EAWM intensity was consistently stronger than that of the reference period in 38 out of the 42 models chosen for analysis, with an average strengthening of 14% across all models. In response to changes in the Earth’s orbital parameters and atmospheric greenhouse gas concentrations, zonal and meridional land–sea thermal contrasts and sea-level pressure gradients were enhanced between the continent and the adjacent oceans of East Asia, leading to the strengthening of the mid-Holocene EAWM. In addition, there were uncertainties regarding the EAWM reconstructions and the effect of dynamic ocean and vegetation on the EAWM change during the mid-Holocene.

“…The ratio χ ARM /SIRM is also a useful proxy of the representation of fine ferrimagnetic grains in magnetic mineral assemblages and can be used as an indicator of the degree of pedogenic development of loessic soil units. Therefore, χ ARM /SIRM has been widely used to assess the degree of pedogenic development in Xinjiang area and in the Mu Us desert (Chen et al, 2016;Gao et al, 2019;Zhao et al, 2016). The high values of χ ARM /SIRM indicate relatively strong pedogenic intensity.…”

Arid central Asia is one of the most important nonzonal arid regions in the central and eastern part of the middle latitude Eurasian continent (Chen et al., 2008). Northeastern arid central Asia is one of the most important sources of Asian dust due to its unique geomorphic features and dry climate (Kim & Kai, 2007; Shao & Wang, 2003). It has been demonstrated that the solar radiation balance at the Earth's surface, global atmospheric CO 2 concentration, and global hydrological and biogeochemical cycles can be influenced by dust emissions (e.g., Booth et al., 2012; Ginoux et al., 2004). As a significant natural hazard, dust activity is usually related to dust emissions (Dun, 2019), and the temporal trend in dust activity in the area is closely linked to the near-surface wind (Pi et al., 2017; Xi & Sokolik, 2015). However, there are few studies of wind dynamics on a long temporal scale, such as that of the Holocene, and the lack of knowledge of the trend of variation of near-surface wind strength on a long time scale makes it difficult to determine the factors influencing dust activity in this area. The grain size of bulk samples from loess-paleosol sequences in East Asia has been used as a proxy for the East Asian winter monsoon (Xiao et al., 1995). However, bulk samples of Aeolian sediments comprise both pedogenic clay deflated from the dust source regions and argillic clay produced during postdepositional pedogenesis (Z. An et al., 1991; X. Liu et al., 1992). The clay from postdepositional pedogenesis results in a reduction of the grain size of bulk samples, thereby potentially obscuring information about aeolian transport conditions (Xiao et al., 1995). Quartz is one of the most resistant minerals and its physical and chemical properties are very stable during erosion, transport, postdepositional weathering, and pedogenesis. Thus the
