China, too. Why is the temperature difference between north and south so big?
1. Geographical location and latitude are different: the north is located in high latitudes and receives less solar radiation, so the sun shines directly into the southern hemisphere in winter, resulting in less solar radiation and lower temperature in the north. On the contrary, the south is located in the low latitude area and receives more solar radiation, so in winter, the sun shines directly into the southern hemisphere, and the south still receives more solar radiation, and the temperature is relatively high.
2. Different climatic conditions: The northern winter is affected by the cold high pressure in Mongolia and Siberia, and the cold air often goes south to form a cold wave, which greatly reduces the temperature. The south is warm and humid by ocean currents, and the winter is mild. In addition, the southern coastal areas are rich in water vapor due to the warm current, and the inland water vapor is relatively scarce, which also affects the temperature.
3. Different topographical factors: the northern terrain is flat, cold air and moisture are easy to spread and communicate, and the climate changes drastically. The south is dominated by mountains, criss-crossing, cold air and moisture are difficult to spread, and the climate is relatively stable.
To sum up, the large temperature difference between north and south is the result of the joint action of geographical location, climatic conditions and topography.
