It is very cold in the north. Where is it hot?
First, because the north is closer to the North Pole, cold air has a greater impact on the north. Compared with the south, Dabei is closer to the North Pole, and cold air moves from the North Pole to the south. So cold air will have a greater impact on the north. The power of the same cold air is greatly reduced in the south, and it is not so cold in the south.
Second, the daylight hours in the north are shorter than those in the south. In the north, the sunshine time in winter is very short. Relatively speaking, the sunshine time in the south is much longer. Therefore, on the same day, the sunshine time in the south is long, and naturally the temperature in the south will be higher. In fact, this is because the direct point of the sun in winter is in the southern hemisphere, so the closer to the south, the longer the sunshine time will be.
Third, the sunshine intensity in the north is weaker than that in the south. At the same time, the sunshine intensity in the north is not as strong as that in the south. In the north, the winter sun doesn't seem to feel much about the skin. But in the south, the sun will feel very hot when it hits the skin. So because the sunshine intensity in the north is weak, the temperature in the north is lower.
Therefore, it is not difficult to understand why the temperature difference between north and south is so large through the above analysis. Do you think this explanation is understandable?
