Estimates of critical ground surface condition for Asian dust storm outbreak in Gobi desert region based on remotely sensed data

Impacts of Underlying Surface on the Dusty Weather in Central Inner Mongolian Steppe, China

“…These studies concluded that dusty weather often occurs when the vegetation coverage is less than 20% in Junggar. For the measurement of soil moisture, scholars have used global grid data (J. J. Gao et al., 2021; Lee & Kim, 2012; Wu et al., 2016), remote sensing satellite inversion (Kim et al., 2013; Zhao et al., 2016), soil moisture models (Demura et al., 2015; Do & Kang, 2014; Kimura et al., 2009; X. Wang et al., 2021), and measured data (Z. J. Li et al., 2005; Luo et al., 2021; Zhao et al., 2021) to study the relationship between soil moisture and dusty weather. However, there were large differences in the soil moisture results, which may be due to the large difference in soil moisture obtained by different models, or the low accuracy of global grid data, which is not applicable for this study.…”

Imaging of micro-organisms on topsoil particles collected from different landscape in the Gobi Desert

“…The destroyed topsoil is exposed to wind, making dust more likely to occur than in the past. Also, there is the possibility that various microorganisms are attached to the soil particles [5][6][7][8][9]. Dust storms in arid and semiarid areas are not only effected by weather conditions such as strong winds at the time of occurrence, but also effected by the surface condition (for example, conditions of soil dry condition, vegetation, snow cover etc.).…”
