Why is the temperature difference between day and night large in Xinjiang?
The weather is clear during the day, and the air has a weak weakening effect on solar radiation. The solar radiation reaching the surface is more and the temperature is higher. The weather is clear at night, and the air has a weak heat preservation effect on the ground (the atmospheric inverse radiation is weak), so the heat stored on the ground is greatly lost, the heat stored on the ground is greatly reduced, and the temperature is low.
The temperature difference is large, the sunshine time is sufficient (the annual sunshine time is 2500 ~ 3500 hours), the precipitation is small and the climate is dry. The average annual precipitation in Xinjiang is about 150 mm, but the precipitation varies greatly from place to place. The temperature in southern Xinjiang is higher than that in northern Xinjiang, and the precipitation in northern Xinjiang is higher than that in southern Xinjiang.
According to the extended data, Leng Yue in Xinjiang is the most (65438+ 10 month), and the average temperature in Junggar basin is below minus 20℃. The absolute minimum temperature in Fuyun County on the northern edge of the basin reaches-50. 15℃, which is one of the coldest areas in China.
In the hottest month (July), the average temperature in Turpan, known as "Huozhou", was above 33℃, and the absolute maximum temperature reached 49.6℃, ranking first in the country. Due to the great temperature difference between spring, summer, autumn and winter in most parts of Xinjiang, there has always been a saying that "wear leather clothes at noon and eat watermelon around the stove".
Xinjiang is located in the hinterland of Eurasia, with a land border of more than 5,600 kilometers, bordering Russia, Kazakhstan, Kyrgyzstan, Tajikistan, Pakistan, Mongolia, India and Afghanistan. Historically, it was an important passage of the ancient Silk Road, and now it is the only place where the second "Eurasian Continental Bridge" passes, and its strategic position is very important.
There are 46 ethnic groups in Xinjiang, mainly Han, Uygur, Kazak, Hui, Mongolian, Kirgiz, Xibe, Tajik, Uzbek, Manchu, Daur, Tatar and Russian. It is one of the five minority autonomous regions in China. According to the results of the sixth national census, Xinjiang ranks fifth in the proportion of people with higher education in 24 provinces and cities.
Xinjiang will fully implement the 14 free education policy in southern Xinjiang, promote 14 free education in other regions, and gradually realize 15 free education in the whole region, that is, 3 years before school, 6 years in primary school, 3 years in junior high school and 3 years in senior high school.
