the presence of the Intertropical Convergence Zone,ITCZ, in the southern Sahara Desert prevents moisture from reaching the area, while storms north of the desert stop before reaching it as well. As a result, the annual rainfall in the
The dry climate is found where the annual precipitation (\(P\), in mm) is less than \(R\). Then, the dry climates are further divided into steppe (\(P > 0.5R\)) and desert (\(P < 0.5R\)) climates. However, the annual mean temperature in the transition zone between the Sahara...
The center of the desert is the most arid zone, with little precipitation and practically no vegetation. The northern and southern Sahara has shrubs, grasslands, and even trees in areas that receive more precipitation. Vegetation grows freely in the oases and the Nile River Valley. In fact, ...

Recently, the Sahara Desert, the world’s largest desert, has been experiencing frequent heavy rainfall. In northern Morocco, an extraordinary scene of “lakes emerging in the desert” has occurred due to torrential downpours, leading to floods unseen in
Hidden by sand seas and rocky desert are the assets that make Fezzan so strategically desirable: vital oil fields, access to massive subterranean freshwater aquifers, and a number of important Qaddafi-era military airbases. A principal concern is the ability of radical Islamists to exploit Fezzan...

The Sahara Desert has expanded by about 10 percent since 1920, according to a new study by University of Maryland scientists. The research is the first to assess century-scale changes to the boundaries of the world's largest desert and suggests that othe
