Why is the weather so different between the north and the south?

The climate difference between north and south is obviously manifested in:

1, large temperature difference. The northern region is hot in summer and cold in winter, and the temperature is high all year round. The south is hot in summer and warm in winter, and the annual temperature difference is smaller than that in the north.

The main reason for the large temperature difference in winter is the large latitude difference and the high latitude in the north. Compared with the south, the solar altitude angle in winter is small, the daytime is short, and there are many sunny days, and the received solar radiation energy is not much different. The northern region is close to the source of winter wind, which is greatly influenced by winter wind and has low temperature; Due to the blocking of Qinling Mountains and other mountains, the southern region is less affected by the winter wind and warmer.

2. The precipitation varies greatly. The climate in the south is humid, with more precipitation and less precipitation in the north.

Reason: The summer monsoon landed from the southeast coast, and the precipitation brought by it affected our country from south to north. So there is a lot of precipitation in the south. The rainy season starts in April and ends at 10. The rainy season in the north is in July and August, and the rainy season is very short.
