Editing Sahara desert (ecoregion) (section)

===Climate===
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 {{convert|30|C|F}} and the average high temperatures in summer are over {{convert|40|C|F}} for months at a time, and can even soar to {{convert|47|C|F}}. In desert rocky mountains such as the [[Tibesti]] in Libya or the [[Hoggar]] in Algeria, average highs in summer are slightly moderated by the high elevation and are between {{convert|35|and|42|C|F}} at {{convert|1,000|to|1,500|m|ft}} elevation. Daily variations may also be extreme: a swing from {{convert|37.5|to|-0.5|C|F|0}} has been observed.<ref name=WWF>{{WWF ecoregion|id=pa1327|name=Sahara Desert|accessdate=2011-03-21}}</ref> Typical temperature swings are between {{convert|15|and|20|C-change|F-change}}.

Precipitation in the Sahara Desert is scarce, as the whole desert generally receives less than {{convert|100|mm|in}} of rain per year except on the northernmost and southernmost edges as well as in the highest desert mountains. More than half of the desert area is hyper-arid and virtually rainless, with an average annual precipitation below {{convert|50|mm|in}} and many consecutive years may pass without any rainfall. The south of the Sahara Desert, along the boundary with the [[hot semi-arid climate]] (''BSh'') of the [[Sahel]], receives most of its annual rainfall during the highest-sun months (summer) when the [[Intertropical Convergence Zone]] moves up from the south.<ref name=WWF/> [[Windstorm|Wind-]] and [[sandstorm]]s occur in the early spring. Local inhabitants protect themselves from the heat, the sunshine, the dry air, the high diurnal temperature ranges, and the sometimes dusty or sandy winds by covering their heads, such as the [[Tagelmust|cheche]] garment worn by [[Tuareg people|Tuareg]].
