What are the wonders of the climate in the Sahara Desert?

Almost 1/3 of the African continent is occupied by the Sahara Desert. This region has some unique climatic wonders.

Phantom Rain

Sometimes cold air flows over the desert, dark clouds gather, and showers may fall. But due to the extreme heat and dryness at low altitude, the raindrops evaporate before they reach the ground. People call it "phantom rain."

Rainstorm and sandstorm

The sandstorm in the Sahara is connected with the Simon wind. The process is as follows: clear sky and scorching sun. In the desert, a strange sound came from the sky, high and discontinuous, intermittent. This was the "Song of the Desert". After the sound, the tops of the dunes began to move, and the hot air swept the sand into the sky, forming a huge sound. The yellow sand stood high in the sky, spinning endlessly. The sun turned from dark red to disappearing. Suddenly, a strong wind blew up, and the yellow sand hit the face like needles, and the sandstorm began. Rocks as big as eggs were blown all over the ground, and the heavy camel saddles were thrown hundreds of meters away. The sand thrown up by the storm fell rapidly from the sky, putting people in a very dangerous situation. The sandstorm was raging, and the local Arabs in robes and turbans bundled up tightly and hunched over against the wind, quickly walked to a nearby leeward place to take shelter. Sandstorms usually only last for two or three hours, and of course there are some. One or two days. If the expedition encounters this kind of weather, it will be very dangerous.

Dry fog

When there is little wind over the desert and the air is full of dust. , dry fog will appear. At this time, visibility is extremely low, and even the camels, known as the "Ship of the Desert", will lose their way. Therefore, the Saharan people are accustomed to building a pile of stones at certain intervals on both sides of the road as road signs. , to prevent getting lost

Strange "gunshots"

The temperature in the desert is often above 50℃ at noon in summer, and the sand surface temperature is as high as 70℃~80℃; however, at night The wind is howling, and the temperature can drop to 0°C. The rocks expand and contract easily, and people living in the desert hear the sound of rock cracking at night, which sounds like thunder, war drums, or gunshots. People who know it are really horrified when they hear it.
