Why is the weather in the north colder than that in the south?

In winter, the north is farther away from the sun.

In winter, the direct point of the sun moves south to the tropic of Capricorn, and then turns back to the north. In the northern hemisphere, winter is the coldest season, and even the temperature in temperate zone may drop below 0℃. In winter, there will be snowfall in many places, and the snow and ice in most parts of the north will not melt until spring.

Cold air is generally at high latitudes, and the north is close to the cold air area. The north is short of water. Physically speaking, the specific heat capacity of water is relatively small (that is, absorbing 1 can release more heat). The north of China is short of water, while the south is rich in water resources. The north is located at high latitude, and the sunshine is not as good as that in the south.

Extended data:

The northern part of China is mainly characterized by north temperate zone and temperate monsoon climate. The climate is characterized by four distinct seasons throughout the year, high temperature and rainy summer and cold and dry winter.

The annual precipitation in the northern region is mostly 400-800 mm, and it is concentrated in July and August, with heavy rain. At this time, the river is skyrocketing and the river is easy to flood. But every spring, there is little rain and frequent drought (severe spring drought and heavy rain in summer).

Since 1992, except for 1998, the precipitation in northern China in February and April in other years is lower than the average for many years. At this time, under the influence of La Nina phenomenon, the northerly airflow prevails in northern China, while the warm and humid airflow in the southeast is relatively weak. Coupled with the unfavorable cooperation of cold and warm air, the northern region has not formed ideal rainfall conditions, resulting in continuous lack of rain and drought.
