  • Arid area ; Australia ; Desert ; Dust storm ; Model ; Queensland ; Soil erosion ; Suspended load ; Wind erosion
  • The purpose of this paper is to quantify the amount of dust moved in a dust storm in Western Queensland in 1987, and to describe the environmental effects (present and past) of dust entrainment, transport and deposition in the Australian region.
  • Quantitative estimates of the effect of climate change on dust storm activity in Australia during the Last Glacial Maximum
  • Aeolian features ; Aeolian transport ; Australia ; Climatic variation ; Dust storm ; Global change ; Lateglacial ; Quaternary ; Spatial variation
  • Quantitative estimates are made of the effect of climate change upon dust activity during the Last Glacial Maximum (LGM), which peaked 18,000 years ago, using present-day measurements of the occurence of dust storms recalculated in the light
  • of information on LGM climatic change. Dust storm seasons were lengthened and dust paths were modified. Estimates based upon climate alone, without considering the increased supplies of sediment to dust source areas during the LGM, however, probably underestimate
  • LGM dust activity.
  • The influence of different underlying surface on sand-dust storm in northern China
  • Arid area ; China ; Duricrust ; Dust storm ; Lithology ; Northern China ; Sand ; Surface deposits ; Wind
  • In this paper, a quantitative research on the relationship between different underlying surface and sand-dust storm has been made by using 40 years meteorological data of 5 different types of underlying surface in northern China, which include
  • farmland, grassland, sandland, gobi and salt crust. These data comprise sand-dust storm days and strong wind days. The AA. find that there are certain correlations between the days of sand-dust storm and strong wind for different underlying surfaces, which
  • has great influence on sand-dust storm. There are pronounced differences in different types of underlying surface.

  • Dust storms evolution in Taklimakan Desert and its correlation with climatic parameters
  • Arid area ; China ; Climate ; Climatic data ; Desert ; Dust storm ; Human impact ; Precipitation ; Temperature ; Wind speed ; Xinjiang
  • Based on the sand dust storms data and climatic data in 12 meteorological stations around sand dust storm originating areas of the Taklimakan Desert, the AA. analyzed the trends of the number of dust storm days from 1960 to 2005 as well
  • as their correlations with temperature, precipitation, wind speed and the number of days with mean wind speed >5 m/s, to determine the influence of climatic parameters on sand dust storms. The results show that the frequency of dust storm events in the Taklimakan region
  • decreased with the elapse of time. Climatic factor is one of the major conditions for the occurrence of sand dust storm, but not the only one. The disturbance of human activities will become another important trigger for China's frequent sand dust storms.

  • Australia ; Climatology ; Correlation ; Drought ; Dust ; Dust storm ; Precipitation ; Victoria ; Wind
  • The AA. use dust records at Mildura, Australia along with observed wind directions during dust storms and events and both local and regional source area rainfall for the period 1960-1989 to test the adequacy of using local rainfall and to show
  • the improvement that could be achieved by using regional rainfall in the likely dust source area.
  • Sand dust storms in and around the Ordos Plateau of China as influenced by land use change and desertification
  • Aeolian features ; Arid area ; China ; Desertification ; Dust storm ; Inner Mongolia ; Land use ; Shaanxi ; Soil degradation ; Wind erosion
  • The A. reports a non-linear relationship between sand-dust storm frequency and the index of land degradation which is defined as the percentage of the area of total land that is desertified. Using this non-linear relationship, a threshold
  • is established which means that sand-dust storm frequency would increase abruptly when the human-induced exceeds 30%. The time series of annual number of sand-dust storm days in the neighbouring area has been compared to the time series in the annual number

  • Possible influence of Arctic Oscillation on dust storm frequency in North China
  • Air mass ; Atmospheric dynamics ; China ; Climate oscillation ; Climatology ; Cold front ; Correlation ; Dust storm ; Northern China ; Simulation ; Statistical analysis ; Synoptic climatology
  • This study has investigated the influence of Arctic Oscillation (AO) on dust storm frequency in North China in spring seasons during 1961–2007. There is a significant linkage between dust storm frequency and AO; a negative (positive) AO phase
  • is related to an increased (decreased) dust storm frequency in North China. This relationship is closely related to changes in the cold air activity in Mongolia. The cold air activity exerts large impacts on the dust storm frequency; the frequency of cold air
  • activity over Mongolia not only positively correlates with the dust storm frequency in North China, but also shows a long-term decreasing trend that is an important reason for the long-term decreasing of dust storm frequency in North China.
  • Studies on eolian dust in Greece

  • Wind tunnel experiments and field measurements of aeolian dust deposition on conical hills
  • The spatial pattern of short-term aeolian dust deposition on and around cone-shaped hills is investigated via the simulation, in a wind tunnel, of dust storms over a topographic scale model of a conical hill in the Negev desert, Israel. The results
  • are tested during a full-scale dust storm in the Negev.
  • Dust storm erosion and its impact on soil carbon and nitrogen losses in northern China
  • Agricultural practice ; Arid area ; Carbon ; China ; Dust storm ; Nitrogen ; Northern China ; Nutrient ; Soil conservation ; Soil erosion ; Wind erosion
  • This paper reviews the recent literature concerning dust storm-related soil erosion and its impact on soil C and N losses in northern China. The purpose of this study is to provide an overview of the area of erosion-affected soils and to estimate
  • the magnitude of soil C and N losses from farmland affected by dust storm erosion. The results indicate that soil conservation measures along with improved soil fertility management measures should be promoted in dry-land farming areas of northern China.
  • Effects of spatial variations in source areas upon dust concentration profiles during three wind erosion events in Australia
  • Aeolian features ; Aeolian transport ; Arid area ; Australia ; Dust storm ; Erodibility ; Floodplain ; Model ; Queensland ; Spatial variation ; Wind erosion
  • Dust storms are a major contributor to soil erosion in inland Australia, and the Simpson Desert-Channel Country region is one of the most active wind erosion regions. While information is available on wind erosion rates at the land-type level
  • , little is known about the influence that spatial variations in the erodibility within a land type have on the resulting dust concentration profile. A Gaussian plume model, DSIS, is presented along with tower-based dust data, to describe the influence
  • of different spatial combinations of dust source areas, during 3 dust events on the Diamantina River floodplain in Western Queensland, Australia.

  • Studies of recent dustfall in the Western and Eastern Mediterranean islands and mainlands give support to the hypothesis of eolian dust deposition from Africa. It is probably an important contribution to soil formation, slope wash and stream
  • sediments in the Mediterranean area. The quantitative role of African dust input, its history and distribution in time and space ought to be the subject of continued research.

  • collected at 12 localities during September 2008 and July 2009 with and without transboundary dust storms, respectively. The findings, together with satellite images and patterns of wind frequency and direction, clearly indicate the major contribution
  • of a transboundary dust storm, probably originating from iraqi arid land, to atmospheric deposition in the Zagros area and central Iran. If dust storms originating from outside the country continue to occur, not only will they influence the surface soil properties
  • The aim of this study was to identify the variations in physical, chemical, and mineralogical composition of dust particles deposited along an elevational transect lying between central Iran and the Zagros Mountains in the west. Dust samples were
