Adrar ( ar, ولاية أدرار, ber, ⴰⴷⵔⴰⵔ) is a province (''wilaya'') in southwestern Algeria, named after its capital Adrar. It is the second-largest province, with an area of 424,948 km2, roughly the size of the US state of California. It had 402,197 inhabitants at the 2008 population census. It is bordered by five other wilayas: to the west by Tindouf; to the north by Béchar and El Bayadh; to the east by Ghardaïa and Tamanrasset. To the south, it is bordered by Mauritania and Mali. Adrar is composed of three natural and cultural regions: Touat (Adrar, Zaouiet Kounta), Gourara (Aougrout, Timimoune) and Tidikelt ( Aoulef), and 299 '' ksour''.

Reggane
Reggane (from Berber "Argan"; ar, رقان) is a town and commune, and the capital of Reggane District, in Adrar Province, central Algeria. Reggane lies in the Sahara Desert near an oasis. According to the 2008 census it has a population of 20,402, up from 14,179 in 1998, with an annual growth rate of 3.8%. Berber tribes and people live in and around Reggane. History To the east of Reggane there was, until 1965, a rocket launching site where numerous civilian and military ballistic rockets were launched. France began its nuclear testing program in the vicinity of Reggane, conducting four such tests during the Algerian War in 1960 and 1961, before independence. Geography The town of Reggane and its neighbouring villages lie next to the southernmost oasis of the Tuat region, which stretches northward to Adrar. The Tidikelt region, a plain with isolated oases, lies to the east, including towns such as In Salah, In Ghar, Aoulef and Tit. To the west is the sandy Erg Chech desert, w ...

Tanezrouft
The Tanezrouft ( ar, تنزروفت) is a natural region located along the borders of Algeria and Mali, west of the Hoggar Mountains. Along with the Libyan Desert it is one of the most desolate and most arid parts of the Sahara Desert. This area has no permanent residents and is known for its soaring temperatures and scarce access to crucial resources: water and food. Due to this, it is commonly referred to as the "land of terror". Natural regions Geographic features The Tanezrouft is a vast barren plain extending to the west of thAdrar Ahnet southeast of the Erg Chech sand sea, and north of the Adrar des Ifoghas hills in northern Mali. Almost all in Algeria, the Tanezrouft is notoriously flat, featureless and without wells. In 1922 the firm gravel plain enabled the first crossing of the Sahara by motor vehicle. The terrain shows stark evidence of long-ago water erosion (when the Sahara Desert's climate was much wetter; present annual rainfall is much less than 20 mm). In the ...

Hot Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid sub ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
