Characteristics of temperature distribution in winter and summer in China and its influencing factors

In winter, the temperature difference between north and south is large, the south is warm, and the farther north, the lower the temperature.

In summer, the temperature is generally high in the north and south, and the lowest temperature is on the Qinghai-Tibet Plateau.

The reasons are as follows

Let me start with the winter.

Considering the location of land and sea, the north is less affected by the ocean than the south, and the cooling rate is faster.

Considering the latitude position, the northern latitude is high, the sun height is small and the sunshine is short.

Considering the atmospheric circulation, the north is close to the cold source of Mongolia and Siberia.

Judging from the ground situation, there is much snow in the north, and the solar radiation reflectivity is high, so the ground is not easy to be heated.

So the temperature difference between north and south is large.

Let's talk about summer:

In summer, the sun in the south is high and the sunshine time in the north is long, which offsets each other.

It's cloudy in the south and sunny in the north in summer, which offsets it.

The north is less affected by the ocean and heats up quickly.
