• Hot, dry winds, such as the khamsin in Egypt and the sirocco in northern Africa, blow sand across the desert, making conditions even more difficult.

• The Atacama desert in northern Chile in South America is the driest place in the world. Some weather stations in this desert have never re corded any rain

• Mists are common in the coastal parts of deserts like the Atacama and the Kalahari.

• The fog that forms over the ocean is blown inland by the wind. Moisture from fog drip is sufficient to support a vegetation cover on the coastal hills
