The Ghibli, a local name for the Sirocco in Libya, is a hot and dry south or southeasterly wind that stirs up dust and sand.
These troublesome winds can last for days and change the desert landscape by rearranging vast quantities of sand.
Remember the sandstorm scene in the movie The English Patient? The jeeps were buried completely. When the storm was over, they had to be dug out before the occupants ran out of air.
Like other winds, the Ghibli has been grabbed for advertising, for instance, a Ghibli vacuum cleaner.
