What seems extreme to us is actually a common occurrence in Africa and the Middle East. The similar sand-saturated hurricane-speed storms over Mediterranian are called Sirocco, Yugo and Ghibli. The dust (or desert sand) particles become airborne and held in suspension, creating a moving front. The convection of cold air over the heated ground maintains the storm and keeps the dust rolling.

This Dust-Storm-look-alike is actually a "Cloud Front Australian Outback".
Here is an alarming fact: Sand storms now happen ten times more frequently than fifty years ago. For example, Mauritania had only two storms per year in the early Sixties, now it's more like EIGHTY a year. Sahara's sand is also being sent into the Atlantic at an accelerated pace (five times growth in one year, since 2006!) - however, this could be a good thing, according to Wikipedia, as it will cool off the ocean enough to slightly ease the ongoing 2007 hurricane season.
