What's so special about the climate in the Sahara desert?

The Sahara desert occupies almost one third of the African continent. There are some unique climate wonders in this area.

Dream rain

Sometimes cold air flows over the desert, dark clouds gather and showers are welcome. However, due to the extreme heat and dryness at low altitude, the raindrops evaporated before landing. People call it "magic rain"

Rain, steam, wind and sandstorm

Sandstorms in the Sahara desert are related to Simon wind. The process goes like this: In the clear Wan Li and the scorching desert, there is a strange sound in the sky, which is high and discontinuous, and sometimes it doesn't exist. This is the song of the desert. After the sound, the peak of the sand dune began to move, and the hot air swept the sand into the sky, forming huge yellow sand grains, which stood tall and whirled. The sun changed from dark red to disappearing color. In an instant, the wind was blowing and the yellow sand was all over the sky. Yellow sand hits the face like a needle, and even pierces the skin and oozes blood. The sandstorm began, blowing rocks the size of eggs all over the floor and throwing the heavy camel saddle hundreds of meters away. Sands rolled up by the storm fell from the sky, putting people in a very dangerous situation. Whenever a sandstorm rages, local Arabs in robes and headscarves will wrap themselves up, bend over against the wind and quickly run to nearby leeward places to escape. Sandstorms usually last only two or three hours, but of course they last for a day or two. If the expedition encounters this weather, it will be very dangerous.

thick haze

When there is almost no wind over the desert and the air is full of dust, dry fog will appear. At this time, the visibility is extremely low, and even the camel known as the "boat of the desert" will lose its way. Therefore, Saharans used to pile up a pile of stones as road signs at regular intervals on both sides of the road to prevent getting lost.

Strange "gunfire"

At noon in summer, the temperature in the desert is often above 50℃, and the temperature of the sand surface is as high as 70℃ ~ 80℃. However, at night, the wind is howling and the temperature can drop to 0℃. Rock expands with heat and contracts with cold, so it is easy to crack. People who live in the desert hear the sound of rocks breaking at night, just like thunder, drums and gunshots. People who don't understand are really scared.
