Its area of is comparable to the area of China or the United States. The name 'Sahara' is derived from a dialectal Arabic word for "desert", ' ( ). The desert comprises much of North Africa, excluding the fertile region on the Mediterranean Sea coast, the Atlas Mountains of the Maghreb, and the Nile Valley in Egypt and Sudan. It stretches from the Red Sea in the east and the Mediterranean in title: Desert climate text: Desert climate The desert climate (in the Köppen climate classification "BWh" and "BWk"), also known as an arid climate, is a climate in which there is a excess of evaporation over precipitation. The often bald, rocky or sandsurfaces of arid climates evaporate the scanty precipitation, so that water is too low to sustain little, if any vegetation at all. No part of Earth is known for certain to be absolutely rainless, although in Arica in northern Chile, the average annual rainfall over a period of 17 years was only 5 mm (0.2 in.).

Trade wind deserts occur either side of the horse latitudes at 30° to 35° North and South. These belts are associated with the subtropical anticyclone and the large-scale descent of dry air moving from high-altitudes toward the poles. The Sahara Desert is of this type. Mid-latitude deserts occur between 30° and 50° North and South. They are mostly in areas remote from the sea where most of the moisture has already precipitated from the prevailing winds. They include the Tengger and Sonoran Deserts. Monsoon deserts are title: Sahara text: is linked to a marked decline in the scale of the Nile floods between 2700 and 2100 BCE. The Sahara comprises several distinct ecoregions. With their variations in temperature, rainfall, elevation, and soil, these regions harbor distinct communities of plants and animals. The Atlantic coastal desert is a narrow strip along the Atlantic coast where fog generated offshore by the cool Canary Current provides sufficient moisture to sustain a variety of lichens, succulents, and shrubs. It covers an area of in the south of Morocco and Mauritania. The North Saharan steppe and woodlands is along the northern desert, next to
