中高纬粉尘通量记录数据集（6万年以来）

揭示了末次冰期中高纬粉尘堆积不同步变化的现象，推测中纬度粉尘堆积主要与西伯利亚高压有关，高纬粉尘堆积同时与西伯利亚高压强度和西风环流强度有关。基于中亚黄土 30-10 ka 的光释光年代数据分布概率密度函数以及肖尔布拉克和库尔托别两个剖面沉积速率的结果，分析了末次冰期中亚黄土粉尘堆积强度的变化， 发现中高纬粉尘沉积速率出现了不同步变化的现象。这种不同步现象产生的原因主要是，中亚和黄土高原等中纬度地区的粉尘堆积受控于岁差主控的西伯利亚高压强度，而高纬格陵兰和北太平洋等地区粉尘堆积可能同时受控于岁差主控的西伯利亚高压强度和地轴倾角主控的西风环流强度。

This study documents the asynchronous variations of high-latitude dust accumulation during the Last Glacial Period, and proposes that mid-latitude dust accumulation is primarily governed by the Siberian High, while high-latitude dust accumulation is jointly controlled by both the intensity of the Siberian High and the strength of the westerly circulation. Based on the probability density functions (PDFs) of optically stimulated luminescence (OSL) dating data from Central Asian loess spanning 30–10 ka, as well as the sedimentation rate records from the two sections of Xiao'erbula and Ku'ertuobie, this study analyzes the changes in dust accumulation intensity of Central Asian loess during the Last Glacial Period, and finds that asynchronous variations emerged in the dust sedimentation rates between mid- and high-latitude regions. The core reason for this asynchronous phenomenon is that dust accumulation in mid-latitude areas including Central Asia and the Loess Plateau is controlled by precession-forced Siberian High intensity, whereas dust accumulation in high-latitude regions such as Greenland and the North Pacific is likely simultaneously regulated by both precession-forced Siberian High intensity and obliquity-forced westerly circulation strength.
