“…The major source areas of the Asian dust events affecting China are Gobi Desert, Taklimakan desert, and Loess Plateau [130][131][132]. Two major dust outbreaks affecting the region of Beijing are identified in 12-13 and 16-18 March 2014, another episode also identified end of March.…”

Abstract:Mineral dust is one of the most important aerosols over the world, affecting health and climate. These mineral particles are mainly emitted over arid areas but may be long-range transported, impacting the local budget of air quality in urban areas. While models were extensively used to study a single specific event, or make a global analysis at coarse resolution, the goal of our study is to simultaneously focus on several affected areas-Europe, North America, Central Asia, east China and the Caribbean area-for a one-month period, March 2014, avoiding any parameter fitting to better simulate a single dust outbreak. The simulation is performed for the first time with the hemispheric version of the CHIMERE model, with a high horizontal resolution (about 10 km). In this study, an overview of several simultaneous dust outbreaks over the Northern Hemisphere is proposed to assess the capability of such modeling tools to predict dust pollution events. A quantitative and qualitative evaluation of the most striking episodes is presented with comparisons to satellite data, ground based particulate matter and calcium measurements. Despite some overestimation of dust concentrations far from emission source areas, the model can simulate the timing of the arrival of dust outbreaks on observational sites. For instance, several spectacular dust storms in the US and China are rather well captured by the models. The high resolution provides a better description and understanding of the orographic effects and the long-range transport of dust plumes.

“…Several cases of substantial long-range transport of dust from the Sahara have been documented from satellite observations (Anthony, 1978;Carlson, 1979). Other dust outbreaks are sometimes observed over Japan and eastern China (Iwasaka et al, 1983). Individual sandstorms have received less attention (Noyalet, 1978).…”

Although satellite remote sensing of the atmosphere and Earth's surfaze has been pursued now for many years, it has not been applied widely in detailed or systematic investigations of the atmospheric and land surface climates of arid and semiarid regions. This paper briefly surveys characteristics of satellite systems that should be considered when evaluating the present and potential roles of satellite remote sensing in arid and semiarid zone research, and in studies of desertification. Actual and potential applications of satellite data in these research areas are then reviewed. It is concluded that satellite data available for arid and semiarid areas have been used in a very fragmentary and unsystematic manner. Proposals are made for exploiting more fully satellite data, especially in investigations of desertification.

“…A sandstorm is generally defined as a weather phenomenon formed by a strong wind carrying a large amount of dust and sand and can reduce horizontal visibility to less than 1000 m. Blowing sand is generally defined as a weather phenomenon that is also formed by a strong wind carrying large amounts of dust and sand and can reduce horizontal visibility to 10,000-1000 m. In this study, we defined blowing dust events as the sum of sandstorms and blowing sand. Many studies of blowing dust events have been conducted, including investigations of the causes of blowing dust (Brazel and Nickling 1986;Sun et al 2001), the spatial and temporal variations of dust events (Goudie 1983(Goudie , 2009Ganor et al 2010;Guan et al 2014;Washington et al 2003;Wang et al 2005), dust transport (Iwasaka et al 1983;Kimura 2012;Marx et al 2009;Prospero et al 2002Prospero et al , 2014Swap 1992), the contribution to the atmospheric radiation balance and climatic impacts (Gautam et al 2010;Spyrou et al 2013), the impacts on the environment and air quality (Prospero 1999(Prospero , 2014Vianaa et al 2002), and the forecasting of blowing dust events (Astitha et al 2012;Wang et al 2008a). …”

The Taklimakan Desert is the source of most blowing dust events in China. However, previous studies of sandstorms in this region have not included data from the inner desert because of the difficulty in making observations in this area. In this study, the spatial and temporal variations of blowing dust events, including sandstorms and blowing sand, and its relations with climatic parameters in the Taklimakan Desert were analyzed using data from ten desert-edge meteorological stations during 1961 to 2010 and two inner-desert meteorological stations during 1988 to 1990, 1996 to 2010, and 1992 to 2010. The results identified two regions (Pishan-HotanMinfeng and Xiaotang-Tazhong) where blowing dust events occur on average more than 80 days per year. The regions with the highest occurrence of sandstorms, blowing sand, and blowing dust events were different, with sandstorms centered in the north of the desert (Xiaotang, 46.9 days), whereas the central location for blowing sand (Pishan, 86.4 days) and blowing dust events (Minfeng, 113.5 days) activity was located at the southwestern and southern edges of the desert, respectively. The occurrence of sandstorms generally decreased from 1961 to 2010, while the occurrence of blowing sand increased from 1961 to 1979 and then generally decreased. The temporal variation of blowing dust events was mainly affected by the occurrence of strong wind and daily temperature, with average correlation coefficients of 0.46 and −0.41 for these variables across the whole desert.
