Here's why:
* Vast Size: The Sahara is the largest hot desert in the world, covering a vast area. This means there's a lot of loose sand available to be picked up by winds.
* Strong Winds: The Sahara experiences strong, consistent winds, especially during the dry season.
* Lack of Vegetation: The desert's sparse vegetation doesn't offer much resistance to wind, allowing sand to be easily transported.
While other deserts have sandstorms, the Sahara's combination of factors makes it particularly prone to prolonged sandstorms.
