In Xinjiang, the temperature is high in summer and low in winter. Please explain the reason.

Xinjiang lives in the hinterland of the Asian continent, far away from the ocean and surrounded by high mountains, which blocks the warm and humid air flow from the ocean and forms a dry continental climate in Xinjiang. This climate is characterized by drought, little rain, heavy wind and sand, hot summer and cold winter, and large temperature difference between day and night. The reason is that the specific heat capacity of inland areas is very small, and the heat absorbed during the day is not much, which will soon be lost. There is strong sunshine during the day, so the temperature is high during the day. At night, the heat can't be preserved and will be lost soon, so the temperature will drop greatly. In addition, there are many sunny days, and there is no atmospheric reverse radiation at night, so the temperature difference is very large.

I wish you learn geography well.
