It’s another year, north and south"hidden temperature difference"It’s the biggest season. Some people say that the biggest misunderstanding between people in the north and the south is that southerners think northerners are more frost-resistant, while northerners think that winter in the south is not cold. In fact, apart from the temperature difference between the north and the south, there are also these. ……
Recently, there are always friends who punch in one after another in Weibo:
"It’s cool to have heating!"
"I can finally have a good bath."
"It was too hot to sleep, so I opened the window."
"I just hoarded three boxes of Mattel."
……
At the same time,
The mood of the babies in the south is sauce purple
So, what is the real situation in winter in the north and south?
Let’s start with two scenes.
Outdoor articles
Judging from the weather forecast, after entering the deep winter, the average outdoor temperature in the north is basically below zero, and the northeast, Inner Mongolia and other places can even reach below-30℃, which is properly cold!
However, the average temperature in winter in many places in the south is basically above 0℃, which is obviously higher than that in the north in terms of temperature figures.
However, friends who have experienced winter in the north and south all feel that it is colder in the south. ……
What is the reason?
As for whether it is cold in winter in the south or cold in winter in the north, there is a saying circulating on the Internet:The cold in the south is a "magic attack" and the cold in the north is a "physical attack".
Obviously, the temperature is higher but it feels colder. This is actually the feeling of "somatosensory temperature". Somatosensory temperature is a kind of feeling that people get physically or mentally when they come into contact with the external environment through the skin. Because of other climate-related conditions, the thermal convection between air and human body is affected, which makes the temperature that people feel different from the actual situation, so it is also called apparent temperature or perceived temperature, which is affected by many factors such as temperature, humidity, wind and solar radiation.
For example,Humidity effect-Although the temperature in the south is not very low in winter, it is humid wind blowing in the south. The thermal conductivity of humid air is much higher than that of dry air. In cold winter, people will lose more heat in contact with the outside world, and the temperature of the human body is easy to radiate. The temperature of the human body surface is often as low as that of the surrounding area. It is dry wind blowing in the north. Although it is cold, it is only that the surrounding temperature drops, and the temperature of human body surface has not changed much. This is dry and cold.
Studies have shown that for every 10% increase in humidity, people’s somatosensory temperature will decrease by 1℃. In other words, even if the temperature in the south is 3℃ higher, if the humidity is 30% higher than that in the north, the somatosensory temperature will be the same.

Indoor articles
It is often said on the Internet that "I show my waist in the bright sun in the south, and you are wrapped in mink in the cold winter in the north". However, after the heating came in the north, the painting style changed into "You are snowing in the sunny south, and I am like spring in the cold night in the north".
Except for the occasional outdoor activities, most of us spend most of our time indoors during the day. Therefore,From the outdoor to the indoor, this began the real contest of the temperature pk between the north and the south.
Heating is widely used in the north in winter, whether it is unified heating or self-heating, the indoor temperature is generally above 20℃, which is still very warm compared with outdoor. From the outdoor to the indoor, the temperature difference is 30℃ upward, which often has the feeling of changing seasons.
In the south, although it is cold outdoors, it is occasionally blessed by sunlight. The warmth index is not high, but it is not as cold as indoor. There is no sunshine indoors, and the temperature is the same as that outside. The "wet and cold" version is cool for you.

Maybe a little friend asked,
I’m in the south. I’m not cold here. ……
In fact,Not all places have four seasons.. For example, Kunming, Xining and Lhasa have no summer all the year round because of their geographical location and topographical characteristics, and spring and autumn are connected. However, Fuzhou, Guangzhou, Nanning, Haikou, Taipei, Hong Kong and Macao are connected by autumn and spring because of their southerly latitudes.
It’s getting colder every day,
Whether it is a northern friend who lives by heating,
Or the friends who are blessed by quilts in the south,
Keeping warm is king!
