Annual precipitation (mm), annual average temperature (°C), and relative humidity (%) in the eastern, central, and western parts of the northern slopes of the Qilian Mountains (data from China Meteorological Data Network http://data.cma.cn/). (A) Annual temperature at the Jiuquan Meteorological Station during 1951–2017. (B) Annual precipitation at Jiuquan. (C) Relative humidity at Jiuquan. (D) Annual temperature at the Zhangye Meteorological Station during 1951–2017. (E) Annual precipitation at Zhangye. (F) Relative humidity at Zhangye. (G) Annual temperature at the Wushaoling Meteorological Station during 1951–2017. (H) Annual precipitation at Wushaoling. (I) Relative humidity at Wushaoling. Black horizontal lines represent the mean value.

(A) Simulated summer (JJA) 850-hPa wind (UV850; vector, units: m/s), Afro-Asian monsoon domain (black line) and arid domain (orange line) in present day (PD). Monsoon domains at Last Glacial Maximum (LGM) and Holocene Thermal Maximum (HTM) are also indicated by blue dotted and red dashed lines, respectively; (B) Changes of precipitation (Pr; shading, units: mm/month), UV850 (vector, units: m/s), and monsoon domain (black circles) between PD and HTM (PD – HTM); (C) Same as (B), except for changes between HTM and LGM (HTM – LGM); (D) Areal changes (relative to LGM) of monsoon domain over Asia (blue dashed line), North Africa (red dashed line), and Afro-Asian (black solid line) with the unit of %. The multi-model ensemble results of PMIP3 and one intra-model standard deviation range of eight models are plotted in brown dots and bars; and (E–G) Simulated precipitation variation averaged over interior monsoon regions (gray curve; averaged over LGM domain illustrated in (A) and over fringe-migrationing regions (blue curve; averaged over monsoon domain difference between LGM and HTM). Their average values since LGM are labeled in the y-axis (units: mm/month). Records of oxygen isotope of MD03-2707 (Weldeab et al., 2007), Qunf cave (Fleitmann et al., 2003), Dongge cave (Dykoski et al., 2005) and Bittoo cave (Kathayat et al., 2016) are indicated by green/brown dots. The red curve in (B,C) depicts recorded monsoon fringe during HTM (Winkler and Wang, 1993; Adams, 1997; Jiang and Liu, 2007), black curve in (B) PD and blue curve in (C) LGM (Yan and Petit-Maire, 1994).

$Comparison between dust storm history at Lake Karakul (curve i; inferred from the >64 μm sedimentary gain-size fraction; this study), historical dust events frequency records in northern China (curve a; Zhang, 1984), dirty ratio in the Kuokuosele ice core (curve b; Tenzin et al., 2016), Ca concentrations in the Geladaindong ice core (curve c; Grigholm et al., 2015), mean diameter of dust in the Tanggula ice core (curve d; Wu et al., 2013), historical dust events in Korea (curve e; Chun et al., 2008), dirty ratio in the Malan ice core (curve f; Wang et al., 2007), nssMg2+ from ice core in Mt. Logan, Canada (curve g; Kang et al., 2003), and historical dust event records around Lake Karakul (curve h; He et al., 2004). Red thin lines in plots b, c, f, g, and i show the linear trends; the vertical gray shaded bars indicate high frequent/intensive dust storm stages; the pale-yellow rectangle in curve d shows the AD 1930s–1950s dustiness period recorded in Tanggula ice core.$
