Sunny weather

It's snowing heavily in Harbin recently, but it's sunny in northern cities, and even short-sleeved shorts in Hainan, Guangdong. Then why is the temperature difference between north and south so big? This involves geographical knowledge. In winter, the direct point of the sun will reach the southern hemisphere, and the direct point in the southern hemisphere means that the closer to the south, the higher the temperature. The north is far from the direct point of the sun, so the temperature is lower.

In winter all the year round, the direct point of the sun slowly moves to the southern hemisphere, while the cities in the south are all in the southern hemisphere, which leads to the relatively high temperature in the southern region and the sunny phenomenon. Because there is sunshine in the direct sunlight, there will be more hidden heat, and high temperature is also a natural phenomenon. The farther away from the direct point of the sun, the less energy the sun radiates, which will cause people to be miserable, so it will be as cold as Harbin in the north.

Because the direct point of the sun in winter is in the northern city in the southern hemisphere, it has a long night time, usually it begins to get dark around 5: 30, but now northerners have a hard time because of the low temperature and long night time. In the south, because the direct point of the sun is in the southern hemisphere, it will lead to direct sunlight, and the time in southern cities will be longer, so if the day is as long as the night, it will be hotter in the south. Moreover, the cold air starts from the north and then goes to the south step by step, so the temperature in the north will be lower and more severe.

So the main reason why the temperature difference between north and south is so large is that the direct point of the sun is in the southern hemisphere, so you can watch the heavy snow in Harbin, watch the sunny days in the south, and even see the phenomenon that Cantonese people wear slippers, short sleeves and shorts to eat popsicles, which is normal. Similarly, Renye Fang envies northerners for seeing snow, while northerners envy southerners for their fine weather.
