What are the characteristics of temperature distribution in winter and summer in China? What is the reason?

Characteristics of winter temperature distribution in China: the farther north, the lower the temperature, and the farther south, the higher the temperature; The temperature difference between north and south is large.

Reason: In winter, the direct point of the sun is in the southern hemisphere. In the north of China, the height of the sun is small at noon, and the day is short, so the ground gets less heat and the temperature is high. The south is the opposite.

Characteristics of summer temperature distribution in China: the temperature difference between north and south is not big, and the temperature in the whole country is generally high.

Reason: In summer, the direct point of the sun is in the northern hemisphere. In the north of China, the height of the sun is small at noon and the days are long, so the heat gained on the ground is not much different from that in the south. The sun is higher in the south at noon, but shorter in the daytime, and the ground gets a little more heat than in the north, so the temperature in the whole country is generally higher.
