“…Frequent incursions of Asian dust during winter have been found over other regions, from Southeastern China (Wang et al, 2005a;Liu et al, 2008) to North America (VanCuren and Cahill, 2002). Along with this study, they support the idea that ADE reports can underrepresent large areas of dust activity (Prospero et al, 2002), which makes them unreliable indicators for evaluating the regional influence of Asian dust.…”

“…Afternoon incursions like this are common for dust in China, especially between 18:00 and 21:00 (Wang et al, 2005a). The peak could not have come from local emissions, for at least two reasons: (1) Local fugitive dust (from roads and open fields) would have been a minimum then because the wind speed decreased from 3-4 m s −1 to 1 m s −1 at the time of the increase; (2) The peak appeared four hours earlier than the normal midnight peak of pollutants, typically caused by reduced dispersion of local emissions during the afternoon and evening.…”

Abstract. Dust storms from major Asian sources are usually carried by northwesterly or westerly winds over Northern and Southeastern China to the Pacific Ocean. These pathways leave Central and Southwestern China nearly free of incursions. But a strong dust event on 5-6 May 2005 was captured in a 15-month series of weekly filter samples of PM 2.5 at three sites in Chongqing. It illustrated that desert dust can be transported to this region, and sometimes strongly. Annual PM 2.5 and dust were similar at the three sites, but higher than in simultaneous samples in Beijing. High correlations of dust concentrations were found between the cities during spring, indicating that Asian dust affects a broader swath of China than is often realized. During the event, the concentrations of mineral dust were high at all sites (20-30 µg m −3 ; 15%-20% of PM 2.5 in Chongqing, and 15 µg m −3 ; 20%-30% of PM 2.5 in Beijing), and were part of a broader spring maximum. The proportions of crustal elements and pollution-derived components such as Pb, SO

“…Dust aerosol is a chief contributor to the global aerosol loading (Pierangelo et al, 2004). The dust aerosol severely affects the local climate and environment by influencing the atmospheric radiation balance and decreasing atmospheric visibility (Wang et al, 2005). Recent years have witnessed numerous studies on the aerosol radiative properties (Blanco et al, 2003;Gobbi et al, 2003;Immler et al, 2003;Collaud Coen et al, 2004;Papayannis et al, 2005;Balkanski et al, 2007;Zhang et al, 2007;Su et al, 2008;Hong et al, 2008).…”

A case study of dust aerosol radiative properties over Lanzhou, China

Abstract. The vertical distribution of dust aerosol and its radiative properties are analysed using the data measured by the micropulse lidar, profiling microwave radiometer, sunphotometer, particulate monitor, and nephelometer at the Semi-Arid Climate and Environment Observatory of Lanzhou University (SACOL) during a dust storm from 27 March to 29 March 2007. The analysis shows that the dust aerosol mainly exists below 2 km in height, and the dust aerosol extinction coefficient decreases with height. The temporal evolution of aerosol optical depth (AOD) during the dust storm is characterized by a sub-maximum at 22:00 (Beijing Time), 27 March and a maximum at 12:00, 28 March. The AOD respectively derived by lidar and sunphotometer shows a good consistency. The PM 10 concentration and aerosol scattering coefficient share similar variation trends, and their maximums both appear at 22:00, 27 March.The aerosol extinction coefficient and relative humidity have the similar trends and their maximums almost appear at the same heights, which presents a correlation between extinction coefficient and relative humidity known as aerosol hygroscopicity. The relative humidity is related with temperature, and then the temperature will affect the aerosol extinction properties by modifying the relative humidity condition.The aerosol extinction coefficient, scattering coefficient, and PM 10 concentration present good linear correlations. The correlation coefficients of the aerosol scattering coefficients of 450, 520, and 700 nm and PM 10 concentration, of aerosol extinction coefficient retrieved by lidar at 532 nm and PM 10 concentration, and of aerosol extinction and scattering coefficient are respectively 0.98, 0.94, and 0.96.

“…Aeolian dust has a number of environmental effects, for example, on air pollution, on the health of humans and livestock, and on the climate (Miller and Tegen 1998;Wang et al 2005). Many global models have been developed in order to simulate a series of processes, namely, dust emission, transport, and deposition (e.g., Ginoux et al 2001;Woodage et al 2010).…”

Regional Characteristics of Recent Dust Occurrence and Its Controlling Factors in East Asia

Aeolian dust, resulting from wind erosion, is controlled by two major factors: aeolian erosivity (i.e., wind speed) and aeolian erodibility (i.e., land surface conditions). Erodibility factors include a number of land surface parameters that interact in complicated manners. Thus far, the extent to which each of the factors contributes to dust outbreaks, which vary regionally and seasonally, remains unclear. As such, we present a novel map of the controlling factors for dust outbreaks in dryland of East Asia by quantifying the relative contributions of the erosivity and various erodibility parameters to inter-annual dust variations on a station basis during the period of 1999 to 2013. Erosivity controls dust outbreaks in the Taklimakan Desert, west of the Hexi Corridor, and on the north side of the Altai Mountain. On the other hand, dust outbreaks are dependent on erodibility in steppe regions: lower precipitation or less abundant vegetation during the previous summer was found to be related to dusty springs in the Mongolian steppe, whereas the less abundant spring vegetation and reduced snow cover enhanced dust outbreaks in the Inner Mongolian steppe. Anthropogenically restored vegetation in desertified areas was found to be likely to suppress dust outbreaks in the Loess Plateau.(Citation: Wu, J., Y. Kurosaki, M. Shinoda, and K.
