2022121 Overview of PM 10 pollution. A sudden and sharp rise in PM 10 concentration is the main manifestation of strong sandstorms (Chung et al., 2003; Wang et al., 2018).As shown in Fig. 1, PM 10 and PM 2.5 hourly concentrations in Beijing in early 2021 were described. Three sandstorm processes were emphasized separately. The

202211 1. Introduction. Coal is an important energy source in China, accounting for 57.7% of the total energy consumption in 2019 (Xie et al., 2019).Due to environmental concerns, the growth rate of coal consumption has declined in recent years, from 92.3% in 1957 to 72.4% in 2005 (Chen et al., 2020).However, it is expected that by 2030, China's

Sand and Dust Storms World Meteorological Organization
2 Sand and dust storms are common meteorological hazards in arid and semi-arid regions. They are usually caused by thunderstorms or strong pressure gradients associated with cyclones which increase wind speed over a wide area. These strong winds lift large amounts of sand and dust from bare, dry soils into the atmosphere, transporting
