The wall of dust can be miles long and several thousand feet high.
"Organic Farming By Using Saharan Soil: Could It Be An Alternative To Fertilizers?" Gust fronts may be produced by the outflow of rain-cooled air from an intense thunderstorm. Shoot length (cm.seedling-1), leaf area (cm2 seedling-1) and photosynthetic pigments [chlorophyll a, chlorophyll b and carotenoids, mg ml-1 g fresh weight (g fw)-1] have been determined.
Dust and sand storms which come off the Saharan dust storms have increased approximately 10-fold during the half-century since the 1950s, causing Dust storms have also been shown to increase the spread of disease across the globe.Short-term effects of exposure to desert dust include immediate increased Dust storms cause soil loss from the dry lands, and worse, they preferentially remove organic matter and the nutrient-rich lightest particles, thereby reducing agricultural productivity.

What does DUST STORM mean? Dust storm definition is - a dust-laden whirlwind that moves across an arid region and is usually associated with hot dry air and marked by high electrical tension. The vertical extent of the dust or sand that is raised is largely determined by the stability of the atmosphere above the ground as well as by the weight of the particulates.

Saltating sand acquires a negative charge relative to the ground which in turn loosens more sand particles which then begin saltating. See more.
Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another. 39 (1): 29–38
