A number of other factors impact climatic variability within the Sahara also: topography does so, as do ocean currents, the latter of that are liable for the slightly cooler and more humid disorders discovered about the desert’s western margins. Some experts estimate the Sahara became arid about two to three million decades in the past, while others contend that it transpired in advance of this.

The severe weather on the Sahara is characterized by: exceptionally small, unreliable, very erratic rainfall; very high sunshine period values; superior temperatures 12 months-spherical; negligible costs of relative humidity; a substantial diurnal temperature variation; and intensely large amounts of probable evaporation which might be the very best recorded around the world.[twenty]
Hay que tener en cuenta que con el proceso de desertificación que está amenazando a la mayor parte de los suelos del planeta, se pueden dar formaciones de estos desiertos a largo plazo.
