(CNN) — Striking images from the Sahara Desert show large lakes etched into rolling sand dunes after one of the most arid, barren places in the world was hit with its first floods in decades ...
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.
There isn’t much green in the Sahara Desert, but an unusual shift in the weather pattern has caused storms to move where they typically wouldn’t.
On October 14, 2024, rare flooding due to intense and abundant rainfall created and renewed lakes around the town. [2] [3] Extremely rare episodes, but they give an idea of how in the future our planet could bring the sahara desert back to being fertile and rich in water as it was in the past about 9,000 years ago.

The modern, arid Sahara. The Sahara was not a desert during the African humid period. Instead, most of northern Africa was covered by grass, trees, and lakes. The African humid period (AHP; also known by other names) was a climate period in Africa during the late Pleistocene and Holocene geologic epochs, when northern Africa was wetter than today.
The Persian Gulf region is known for its hot and dry weather, though heavy rains causing flooding have also occurred with greater regularity in recent years. [5] [6] Britain's Royal Meteorological Society stated that the likely cause is a mesoscale convective system. [7]
In the southern Sahara, the drying trend was initially counteracted by the monsoon, which brought rain further north than it does today. By around 4200 BCE, however, the monsoon retreated south to approximately where it is today, [36] leading to the gradual desertification of the Sahara. [37] The Sahara is now as dry as it was about 13,000 ...
Calima or Kalima is a term used to describe a meteorological phenomenon that occurs when fine sand and dust particles from the Sahara are lifted into the atmosphere and transported by prevailing winds. It usually happens in the summer and lasts 3-5 days. [1]
