Why is it hotter in summer in Xinjiang than in most parts of China?

1, Xinjiang goes deep inland, and water vapor is difficult to reach, with less precipitation and more sunny days;

2. In summer, the height of the sun in Xinjiang is higher, with more sunny days, longer days and longer sunshine hours, and more solar radiation heat is obtained;

3. Xinjiang is mostly desert, with scarce vegetation and rapid warming in summer;

4. Xinjiang is mostly basin topography, which is not easy to dissipate heat.
