There is a temperature difference in the weather

The temperature in the south has exceeded 30 degrees, while it is still snowing in the northeast, from which we can see the temperature difference between the north and the south. Because the north is closer to Siberia, the plains are most vulnerable to cold air. Before the cold air went south, it was blocked by the mountain peak and blocked the way. It's much colder than before, and it has little impact on the south. In spring, the north is also affected by a cold air mass, and the temperature is relatively low.

Why is the temperature difference between north and south so big?

It's actually quite normal. The winter temperature in Mohe, China can be as low as-30~40 degrees, while the winter temperature in the south may only be-4 ~ 5 degrees, with many degrees. On the one hand, the heat far from the direct point of the sun in the north is naturally very small, on the other hand, the north is greatly affected by cold air and will directly come into contact with the cold current. So it snows early in the north and the snow season lasts for a long time. It snows late in the south, and it doesn't even snow in winter in some places. In early spring, there is still some cold air in the north, and the south enjoys the sea breeze, bringing warm air flow, which is naturally hotter.

The latitude difference between north and south is quite large.

In fact, another reason is that the latitude difference between north and south is relatively large. The latitude in the north is relatively high and the temperature in the south is relatively low. In winter, the north is greatly influenced by monsoon, so the temperature is very low, while the south is blocked by Qinling Mountains, and the cold wind has little effect on it. So the temperature difference between north and south is so great that many southerners can't stand the freezing in the north. In the north, you must burn the kang to keep warm in winter, otherwise you will be too cold to sleep. The cold in the south is just a wet cold, with some light snow, and then the home is also very wet.

Be sure to add clothes when you feel very cold, or you will catch a cold. Cold is also difficult to treat now. After all, some pharmacies don't sell cold medicine, and they have to go to the hospital's fever clinic for testing.
