Environmental magnetism has been widely employed to reconstruct past climate changes on the Chinese Loess Plateau (CLP), and several climofunctions based on the magnetic properties of loess have been developed. However, systematic investigation of the quantitative relationship between topsoil magnetic enhancement and modern climate remains uncommon. In this study, we obtained surface soil samples from 257 sites over the CLP and adjacent regions. From this set, we used 180 samples from sites unaffected by potential contamination to investigate the relationship between the commonly measured magnetic properties of magnetic susceptibility and magnetic remanence and modern climatic variables. The spatial distribution of the results demonstrates a strong NW SE gradient of the magnetic enhancement of surface soils. The results of more detailed magnetic parameters indicate that pedogenic viscous superparamagnetic and stable single-domain particles are mainly responsible for the magnetic enhancement of the soils in the studied region; and that the magnetic grain-size distribution of the ferrimagnetic components of pedogenic origin remains almost constant, independent of pedogenic intensity. The uniform mechanism of magnetic enhancement, mainly linked with the concentration of the pedogenic components rather than with variations in magnetic grain-size, decreases the level of ambiguity in climate reconstructions based on magnetic measurements of Chinese loess. Statistical analyses, including correlation, Principal Component Analysis (PCA) and multiple regression analysis, suggest that annual rainfall rather than temperature exerts the dominant effect on soil magnetic enhancement. Finally, we used the results to develop several transfer functions to reconstruct mean annual precipitation (MAP). Transfer functions based on frequency-dependent susceptibility (chi(fd)) and anhysteretic remanent magnetization (chi(ARM)) provide the most reliable estimates of MAP. This study significantly improves the understanding of the relationship between soil magnetic properties and climate. (C) 2013 Elsevier Ltd and INQUA. All rights reserved.

Optically stimulated luminescence dating of loess in South-Eastern China using quartz and polymineral fine grains

A. Avram, D. Constantin, Q. Hao, A. Timar-Gabor

Summary: Loess deposits in southeastern China are important for paleoclimate reconstruction. Luminescence dating of a loess-paleosol sequence in northern Jiangsu Province using SAR-OSL and pIRIR protocols revealed accurate ages up to -70 ka, confirming Last Glaciation deposition. However, beyond 70 ka, quartz ages are underestimated while pIRIR ages are likely overestimated, highlighting the challenges of dating methods for older samples.

New constraints on the source of loess from U/Th-Pb geochronology of detrital multi-minerals

Guangyan Zhou, Long Li, Guoqiao Xiao, Luo Yan, D. Graham Pearson, Qingzhen Hao, Yuanbao Wu

Summary: This study presents a new approach to determine the provenance of eolian sediments from the Chinese Loess Plateau. By using a multi-proxy (zircon, monazite, and rutile) U/Th-Pb geochronology approach, the researchers found spatial variability in sediment provenance and its potential relationship with westerly/northwesterly winds. These findings have important implications for the study of the provenance of eolian deposits worldwide.

Insolation and CO2 Impacts on the Spatial Differences of the MIS-9 and MIS-11 Climate Between Monsoonal China and Central Asia

Hao Lu, Qiuzhen Yin, Zhipeng Wu, Feng Shi, Qingzhen Hao, Dunsheng Xia, Zhengtang Guo

Summary: In this study, loess records and climate simulation results were used to compare the climate differences between MIS-9 and MIS-11 in China and central Asia. The results showed that MIS-9 was relatively wetter in southern central Asia due to higher insolation and that both insolation and greenhouse gases contributed to slightly higher precipitation and evaporation in northern China during MIS-9 compared to MIS-11. Additionally, the higher insolation and greenhouse gas concentration during MIS-9 generated an anomalous atmospheric circulation pattern similar to the negative phase of the North Atlantic Oscillation, favoring precipitation increase in southern central Asia.

Holocene seasonal temperature evolution and spatial variability over the Northern Hemisphere landmass

Wenchao Zhang, Haibin Wu, Jun Cheng, Junyan Geng, Qin Li, Yong Sun, Yanyan Yu, Huayu Lu, Zhengtang Guo

Summary: The study presents an extensive dataset of Holocene seasonal temperatures reconstructed using pollen records in the Northern Hemisphere. The results show that both summer and winter temperatures warmed in the early to mid-Holocene and cooled thereafter, with variations across different regions. The early Holocene warming trend is consistent with model simulations, but the cooling in winter season is not well reproduced by climate models.

Driving factors of interglacial paleosol formation on the Chinese loess plateau and the effect of precession and ice sheets

Keerthika N. Ranathunga, Peter A. Finke, Qiuzhen Yin, Zhipeng Wu, Qingzhen Hao, Hao Lu

Summary: The loess-paleosol sequences in the Chinese Loess Plateau are an important terrestrial paleoclimate record, but there is still limited quantitative understanding of the response of paleosol development to different climate and environmental factors. This study used combined soil-climate models to investigate the sensitivity of paleosol development to various soil forming factors and the influence of ice sheets and astronomical forcing during interglacials over the past 500,000 years. The results show that precipitation, dust addition, and evapotranspiration are the dominant factors controlling interglacial paleosol formation, and their importance varies between interglacials and for different soil properties. The simulated paleosols mainly result from the joint effect of precession and ice sheets via their control on local climate and show qualitative agreement with observations.

Meltwater Pulse1A Triggered an Extreme Cooling Event: Evidence From Southern China

Luo Wang, Qingzhen Hao, Deguo Zhang, Yafei Zou, Patrick Rioual, Enlou Zhang, Jingjing Li, Hai Luo, Jie Li, Guoqiang Chu, Zhaoyan Gu

Summary: Research has found that the injection of Meltwater Pulse 1A into the North Atlantic weakened the Atlantic Meridional Overturning Circulation and caused severe winter temperature drop in the Northern Hemisphere. This extreme cooling triggered the BOlling warming event and led to the recovery of the Atlantic Meridional Overturning Circulation.

Tectonic Forcing of the Extreme Aridification of the East Asian Interior at Around 900 ka-Insights From the Spatially Inconsistent Magnetization of Chinese Loess

Xinbo Gao, Qingzhen Hao, Chunsheng Jin, Chenglong Deng, Shuzhen Peng, Long Han, Yu Fu, Xuechao Wu

Summary: The upper sandy loess unit L9 on the Chinese Loess Plateau represents aeolian deposition under conditions of extreme aridification, but the forcing mechanism is still controversial. Paleomagnetic studies show that in the eastern CLP, the coarsest part of L9 is remagnetized and has a normal geomagnetic polarity, while in the western CLP, it records a primary reverse polarity. This spatially inconsistent magnetization pattern is mainly due to different magnetic carriers in the two regions (hematite in the west and magnetite in the east), suggesting different dust provenance. This spatial contrast is attributed to the episodic uplift of the northeastern Tibetan Plateau, which also caused extreme aridification of the East Asian interior at approximately 900 ka.

Local Differentiation in the Loess Deposition as a Function of Dust Source: Key Study Novo Orahovo Loess Paleosol Sequence (Vojvodina, Serbia)

Slobodan B. Markovic, Jef Vandenberghe, Zoran M. Peric, David Filyo, Tamas Bartyik, Milica G. Radakovic, Qingzhen Hao, Rastko S. Markovic, Tin Lukic, Nemanja Tomic, Milivoj B. Gavrilov, Aleksandar Antic, Ivana Cvijanovic, Gyoergy Sipos

Summary: Typical patterns of Late Pleistocene loess-paleosol units are preserved in Novo Orahovo brickyard, Northern Serbia. Preliminary luminescence chronology supports the chronostratigraphic interpretations of global isotopic marine climate reconstructions. Magnetic susceptibility and sedimentological evidence show general similarities with marine oxygen-isotope stratigraphy. These records provide new insights into dust accumulation regimes over the eastern side of the Backa loess plateau and offer new paleoenvironmental information for the region. They represent an important step towards establishing a catena from the thin loess-like sediments of the Banat foothills in the east to the thicker and seemingly more complete loess sections of the southeastern and central Carpathian Basin. Grain-size data from the loess record of Novo Orahovo explain the regional differentiation in dust deposition.

Strength of the winter North Atlantic jet stream has deviated from its natural trend under anthropogenic warming

Miaofa Li, Binggui Cai, Slobodan B. Markovic, Luo Wang, Qingzhen Hao, Andy Baker, Milivoj B. Gavrilov, Liyuan Jiang, Fang Wang, Xuefeng Wang, Lisheng Wang, Zhibang Ma, Jule Xiao, Zhengtang Guo

Summary: The North Atlantic jet stream has a significant impact on the climate of the North Atlantic-European region, particularly in winter. Recent observations have shown that the winter jet stream has strengthened over the past 140 years, and this trend has deviated from natural variability. Researchers have discovered that the appearance of the North Atlantic warming hole, caused by anthropogenic forcing, is the most likely explanation for this anomalous trend. Continued global warming may further strengthen the jet stream in the future.

Anthropogenic warming has exacerbated droughts in southern Europe since the 1850s

Wenling An, Chenxi Xu, Slobodan B. B. Markovic, Shanlei Sun, Yue Sun, Milivoj B. B. Gavrilov, Zoran Govedar, Qingzhen Hao, Zhengtang Guo

Summary: Widespread and frequent droughts have affected most parts of Europe over recent years. The onset of the drying trend in southern Europe occurred around the 1850s, and anthropogenic warming has enhanced the strength of land-atmosphere coupling and exacerbated the widespread drying trend since then. This persistent drying trend in southern Europe is likely the result of warming and close coupling between soil moisture and atmospheric temperature.
