what is the temperature in the sahara desert
Sahara Desert (ecoregion) The Sahara Desert features a hot desert climate (Köppen climate classification BWh). The Sahara Desert is one of the driest and hottest regions of the world, with a mean temperature sometimes over 30 °C (86 °F) and the averages high temperatures in summer are over 40 °C (104 °F) for months at a time, and can even soar to 47 °C (117 °F). In desert rocky mountains such as the Tibesti in Libya or the Hoggar in Algeria, averages highs in summer are slightly moderated by the high elevation and are between 35 and 42 °C (95 and 108 °F) at 1,000 to 1,500 metres (3,300 to 4,900 ft) elevation. Daily variations may also be extreme: a swing from 37.5 to −0.5 °C (100 to 31 °F) has been observed.[1] Typical temperature swings are between 15 and 20 °C (27 and 36 °F).
Sahara To the south, the Sahara is bounded by the Sahel, a belt of dry tropical savanna with a summer rainy season that extends across Africa from east to west. The southern limit of the Sahara is indicated botanically by the southern limit of Cornulaca monacantha (a drought-tolerant member of the Chenopodiaceae), or northern limit of Cenchrus biflorus, a grass typical of the Sahel.[10][11] According to climatic criteria, the southern limit of the Sahara corresponds to the 150 mm (5.9 in) isohyet of annual precipitation (this is a long-term average, since precipitation varies annually).[12]
Sahara The name 'Sahara' is derived from ṣaḥārá (‏صحارى‎, pronounced /ˈsˤaħaːraː/), the plural of the Arabic word for "desert".[3][4][5][6]
Sahara 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 the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. To the south, it is bounded by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and the Sudan Region of Sub-Saharan Africa. The Sahara can be divided into several regions including: the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Aïr Mountains, the Ténéré desert, and the Libyan Desert.
