We contend that changes in temperature and wind speed could have dominated the frequency and intensity of dust storms in northwest China during the record periods: temperature controls the wind speed and then the dust storm frequency/intensity; lower temperature corresponding to higher wind speed, and higher dust storm frequency/intensity, and vice versa.

In August 2013, a 1.11-m surface sediment core (KLKL 13-2) was retrieved from the deepest part of Lake Karakul, using a 60-mm UWITEC gravity corer (100% sediment recovery; N 38.4428°, E 75.06104°; and water depth, ∼19.5 m; Figure 1b). 41, 589–595.

With time and more data, the MRO team hopes to better understand the dust towers created within global storms and what role they may play in removing water from the Red Planet’s atmosphere. Sand and dust storms are common meteorological hazards in arid and semi-arid regions.

Arrows show wind field of April-June [850 hPa; 1979–2008 NCEP (National Centers for Environmental Prediction) reanalysis data]. But every decade or so, something unpredictable happens: A series of runaway storms breaks out, covering the entire planet in a dusty haze.

Holocene record of eolian activity from Genggahai Lake, northeastern Qinghai-Tibetan Plateau, China. Lake Karakul, the Muztagata glacier, and the Kuokuosele glacier are all located in the eastern Pamirs, sharing a similar atmospheric circulation background and therefore could have similar dust sources. Sci. Comparison between the dust storm records at Lake Karakul (curve h; this study), annual mean wind speed (curve a; note it is inversely plotted), and temperature (curve b) recorded by 11 stations in the western Tarim Basin (Supplementary Table S1 and Figure 1a), δ18O in Guliya ice core (curve c; Yao et al., 2006), the reconstructed temperature in northwest China by tree-ring width (curve d; Liu et al., 2016), total solar irradiance (curve e; Coddington et al., 2016), annual precipitation recorded at Tashkurghan station (curve f), and sedimentary TOC in Lake Karakul sediments (curve g; Yan et al., 2019). A high-resolution atmospheric dust record for 1810-2004 AD derived from an ice core in eastern Tien Shan, central Asia. Furthermore, the sand fraction (>64 μm) in Lake Karakul correlated well with the average annual wind speed in the west of Tarim Basin (Figures 5a,h; r = 0.46), supporting again that the wind speed could significantly influence the dust storm frequency/intensity, which has been further substantiated in studies in Xinjiang and the Tibetan Plateau (Li et al., 2008; Grigholm et al., 2015).

(2016) presented a significant positive correlation between the Kuokuosele ice core dirty ratio and the observed dust storms over ACA as well as those over northern Tibetan Plateau, suggesting both sources could have contributed dust to the ice core.
Glob. Dust emitted from ACA accounts for ∼25% of total global dust emissions, which may exert significant influences on global climate and hydrological and biogeochemical cycles (Jickells et al., 2005; Uno et al., 2009; Booth et al., 2012), by altering the Earth’s solar radiation budget (Booth et al., 2012), and oceanic primary productivity through iron fertilization (Jickells et al., 2005), etc.

Recent studies suggest that the dust particles with diameters >75 μm could be transported by a long distance (even > 1,000 km; Maring et al., 2003; van der Does et al., 2018). From the dust transport routes proposed by Sun et al. δ18O record and temperature change over the past 100 years in ice cores on the Tibetan Plateau. Dust records from the Malan ice core (Figure 4f) also show that dust events in northern China frequently occurred during the period 1930–1940 AD (Wang et al., 2007). Science 308, 67–71. As the tower decays, it can form a layer of dust 35 miles (56 kilometers) above the surface that can be wider than the continental United States.

Dust towers appear throughout the Martian year, but MRO observed something different during the 2018 global dust storm. Dust particles in the atmosphere will help to create beautiful, vivid sunrises and sunsets, as the dust particles scatter the light. This global dust storm caused NASA’s Opportunity rover to lose contact with Earth. Meteorol.
Lett. And while scientists are still puzzling over the data, two papers recently shed new light on a phenomenon observed within the storm: dust towers, or concentrated clouds of dust that warm in sunlight and rise high into the air. As mentioned in Background and Method, the seasonal distribution of the observed dust storms and strong winds (≥10 m/s) are similar with the maximal peak in spring over the past decades (Figure 1c).

Dust-storm events in Kekexili Area, Northern Tibetan Plateau during the past 4000 years: evidence from grain-size analysis of lacustrine sediments in Kusai Lake. The reconstructed dust storm intensity shows a decreasing trend since AD 1850s, with three high occurrence intervals at AD 1870s–1910s, AD 1930s–1940s, and AD 1960s–1980s.
