The Sahara Desert can scorch people during the day, but why can the temperature instantly drop to sub-zero temperatures at night?

? The Sahara Desert means "Great Desert" in Arabic. It is the sunniest place in the world and one of the least suitable places for biological growth on earth. The Sahara Desert is formed by two climates, the dry subtropical climate in the north and the dry tropical climate in the south. They are characterized by large annual and daily climate changes, which are similar to the climate in my country's Xinjiang region. They have the metaphor of "wearing a fur coat in the morning and wearing a gauze in the afternoon".

? How did this reason come about? Let’s take a look. Precipitation is one of the influencing factors. The annual range of the average daily climate is about 20 degrees, and the average winter temperature is 13 degrees. Early summer was hot, with the highest temperature reaching a record high of 58 degrees. Annual precipitation is 76%, although rainfall varies greatly, with most precipitation occurring between December and March. Heavy rainfall can cause huge flash floods into areas where rainfall does not occur. The dry tropical climate is characterized by a strong annual temperature cycle with the position of the sun; mild, dry winters and hot, dry seasons followed by variable summer rains. The annual average daily temperature difference in the arid tropical zone of the Sahara Desert is 17.5°C (31.5°F). ?The Cold Canary Current on the western edge of the desert lowers the temperature, thereby reducing convective rain, but the humidity increases and fog sometimes occurs. Winter in the southern Sahara Desert is the period of the harmatan, a dry northeasterly wind that carries sand and other small dust particles. ?

??For a long time, the Sahara Desert has been like a natural barrier that hinders travelers from in-depth exploration. Today, several routes across the desert have been opened, making adventurers' dreams come true. Traveling in the desert is a challenge to one's physical strength and intelligence, but it is also strange and exciting: wandering in the long desert, away from the hustle and bustle of the city. It is one of the 10 most bizarre journeys in the world.
