These images, captured by #VIIRS onboard the #NOAA21 satellite on Aug. 30 and Sept. 9, 2024, use enhanced color to highlight rain accumulation in the Sahara Desert.
The Sahara Sea was the name of a hypothetical macro-engineering project which proposed flooding endorheic basins in the Sahara with waters from the Atlantic Ocean or Mediterranean Sea. The goal of this unrealised project was to create an inland sea that would cover the substantial areas of the Sahara which lie below sea level , bringing humid ...
The first documented suggestion for flooding large parts of the Sahara desert was by French geographer François Élie Roudaire whose proposal inspired the writer Jules Verne's final book Invasion of the Sea. Plans to use the Qattara Depression for the generation of electricity reportedly date back to 1912 from Berlin geographer Albrecht Penck. [6]
The precession of the equinoxes is regarded as the most important orbital parameter in the formation of the "green Sahara" and "desert Sahara" cycle. A January 2019 MIT paper in Science Advances shows a cycle from wet to dry approximately every 20,000 years.
About 60 tropical waves leave the coast of Africa each hurricane season. Saharan dust is restricting tropical development but it won't last.
The desert's arid environment causes the soil to become fine and easily lifted by strong winds, such as those associated with the Harmattan or the trade winds. These winds can lift millions of tons of sand and dust into the atmosphere, creating a dense, suspended cloud that can travel thousands of kilometers. [ 4 ]
