Why do southerners like to emphasize that winters are colder than in the north? Is the perceived tem

Because many neighborhoods in the south are not heated, and the winter temperature is lower, southerners like to emphasize that the winter is colder than the north, actuallyFeel the temperatureAnd not too low。Regarding the question of who is colder in the north and south, it will always make netizens argue, many northern friends are tasked with the cold wind in the north, while the southern friends think that the south is cold. Therefore, there is a saying on the Internet that the clammy cold in the south is a "magic attack", while the dry cold in the north is a "physical attack".

Purely from the physical temperature, of course, the cold in the north is better, after all, the temperature of dozens of degrees below zero is really not something that ordinary people can bear, and most cities in the south, the coldest temperature in winter is only about minus 10 degrees, which is far less than the north. The main reason why many southerners like to emphasize the cold of winter is that there is no "way to warm up". As we all know, most of the communities in the north have central heating equipment, although it is very cold outside, but it is warm like spring when you enter the room, which is simply polarizing.

Therefore, even if you are "physically attacked" outside, you can quickly "regenerate" after entering the room. It is said that many people in the area like to buy ice cream in winter to prevent fire. The southern community is completely different, most of them do not have central heating equipment, not only feel cold outside, but still feel cold after entering the house, and there is no relief at all.

If you want to heat the house, you usually need to install floor heating and heating, which is a high investment, and you also need to pay for subsequent operation and use costs, which is not very cost-effective.

In addition, some experts have studied the temperature in the south and found that every 10% of the humidity can reduce the perceived temperature of a person by one degree Celsius.

The daily humidity in the south is usually around 70%, which is why it gives people a feeling of dampness and cold. Many friends in the south have joked that the sun in the south in winter not only cannot warm up, but is like a light in the refrigerator. Therefore, even though the temperature in the south is not low, it gives people a feeling that it is colder than in the north.

There are more cold days in the north than in the south, so the northerners are more cold than the southerners, and the down jackets in the south are thinner than the down jackets in the north, and the pit cold performance is not good, so the southerners like to emphasize that the winter is colder than the north.

Because they have been to the north, they feel that the north is very cold, not as good as the south, because the south is like spring all year round. The lowest temperature in the north can reach a minimum of about 30 degrees. A dog can freeze to death outside.

Really like to emphasize. It's cold. It can reach about minus 40 degrees Celsius. Especially in the Northeast. It's going to freeze you to death.

Winter in the south feels colder than in the north because the relative humidity in the south adds to the chill.

In fact, the north is still colder than the south. One aspect of feeling that the south is colder than the north is, of course, the subconscious is playing tricks, imagining the places with high temperatures to be warmer and the places with lower temperatures to be more cold, and the gap in psychological feelings has created such an impression.

In addition, another factor is naturally related to the fact that there are generally public heating facilities in the north to obtain warmth.

The reason why the same temperature feels colder in the south is that the absolute humidity is about the same as in the north, but the relative humidity is different.

The more humid the air, the greater its thermal conductivity. In winter, the greater the relative humidity of the air, the more likely the human body is to lose heat, and the colder the person will feel. The thermal conductivity of water is relatively large, so moist air is more conducive to heat conduction, so people will feel much colder than dry cold.

The northern part of China is drier and the southern part of the country is more humid, so there is a big difference between the perceived coldness of the human body and the difference between the temperature of the north and the south.

Most people feel that the north is colder than the south, just look at the temperature difference is naturally good, the north is minus ten or twenty degrees, and in some places minus twenty or thirty degrees is also commonplace, while in the south, the lowest temperature is minus two or three degrees, and there are few below minus five degrees, but the cold between the north and the south is not the same, the temperature difference between the indoor and outdoor in the south is not large, and the indoor is very cold in winter; Indoor and outdoor in the north are simply two different worlds, and wearing a thin woolen sweater indoors is just right.

Why? The north is known to be drier, while the south is wetter. The higher the air temperature, the stronger the ability of the air to conduct heat.

This thermal conductivity is somewhat similar to that of wood and iron, and in winter your body feels hotter next to wood than next to iron, because the heat conductivity of the material is different.

The north blows a dry wind, although it is cool, due to the poor heat conductivity, it is not easy to penetrate into the body, and it is not easy to take away the heat of the body. Therefore, the cold in the north is only the low temperature around it, and the cold wind will only take away the heat in the air, so the air temperature is low, and the body temperature of the person has not changed, so we feel that the wind is strong and a little cool. In the south, the wet wind blows, although the temperature is not very low, but it has a strong permeability, which can quickly take away the heat of the human body, and can make the surface of your body as low as the surrounding temperature.

So, we can assume that we are in the north now, and then the temperature around us is minus 10 degrees, but you wear a wool sweater and a down jacket, so your body surface temperature can reach 20 degrees, then you can feel the wind is strong, but you are far from the cold. And in the south, the ambient temperature is three degrees, and you wear a woolen sweater, then your body surface temperature is twenty degrees, wrong! The south is humid and humid, and your skin temperature is close to the surrounding temperature, which is about five degrees.

Look, northerners still have 20 degrees of life in winter, and southerners only have 5 degrees, who is colder? I'm sure fools can see it.

In winter, the north is a little farther away from the sun.

In winter, the direct sun point moves south to the Tropic of Capricorn and then turns back to the north. In the Northern Hemisphere, winter is the coldest season, with temperatures that can drop below 0 even in temperate zones. During the winter months, many places experience snowfall, and the snow and ice in most parts of the north do not melt until spring.

Cold air is generally at high latitudes, near areas of cold air in the north. There is a shortage of water in the north, and from a physical point of view, the specific heat capacity of water is relatively small (that is, absorbing the heat of unit 1 can release more heat). Water is scarce in northern China, while water is abundant in the south.

The north is located at a high latitude, and the sunshine is not as good as that in the south.
