The climate of the Sahara desert

The climatic conditions are extremely bad, which is one of the most unsuitable places for biological growth on earth. Sahara means "big desert" in Arabic. Sahara Desert (English name: Sahara desert) is the most sunny place in the world, and it is also the largest desert with the worst natural conditions in the world.

The climate of the Sahara desert is controlled by the north-south transition of the trade winds, and there are often many extreme situations. It has the highest evaporation rate in the world, and has the largest area record of no rain for several years. At high altitude, the temperature can reach frost and freezing, while at low altitude, the hottest weather in the world can be found.

Extended data:

Water supply system:

Some rivers come from outside the Sahara desert, providing surface water and groundwater for the desert and absorbing the water released by its water network. The main tributaries of the Nile converge in the Sahara desert, and the river flows northward into the Mediterranean along the eastern edge of the desert.

Several rivers flow into Lake Chad in the southern Sahara desert, and a considerable amount of water continues to flow northeast to replenish the aquifer in this area. The Niger River originates in the FoutaDjallon region of Guinea, flows through the southwest of the Sahara desert, and then flows south into the sea.

Soil:

The soil in the Sahara desert is low in organic matter and often has no biological activity, although nitrogen-fixing bacteria exist in some areas. The soil in a depression usually contains salt. The soil at the edge of the desert contains relatively concentrated organic matter.
