What s the coldest weather you ve ever experienced?

Steel below minus 20 degrees is fruity, they all licked it as children, it's better not to try it, the tongue will stick. Because the heat of iron is transmitted quickly, the tongue is quickly cooled, the saliva on the surface of the tongue freezes, and the tongue is frozen on the iron frame. This is also the case with metals such as copper and aluminum.

This is because when a large amount of moisture comes into contact with metal placed outside the cold room, the metal quickly transfers heat from the contact area, causing the moisture on the surface to freeze. Adhesion is caused by icing, and if you pull hard, it will cause peeling and straining of the tongue. But after a while, it will soon dissolve through the flow of blood in the body.

In the winter of Tohoku, it is not easy to touch outdoor metal objects without gloves, so as not to stick a layer of skin, this is the reason.

The water sprinkled on the ground is completely frozen for 5 minutes, the wind blows the face and feels like a blunt cut, there is a thick layer of frost on the window, and you must go out with a down jacket, thick cotton pants and big cotton shoes! I didn't bring an ear bag when I went out yesterday, and I didn't feel my ears when I came back! There is an answer that Zhengzhou is cold, although I have never been to Zhengzhou, but it is definitely a different cold method.

The area in the south is cold without heating, and the wind blows in the east wind. Fortunately, there is heating, there is an earthen kang, and there is sun. If it is not windy, the temperature will rise by 3-4 degrees immediately!

Go out and cover it like a ball.,It's very cute.,Seeing the clean snow in the open space can have a snowball fight at any time.,It's very warm when you enter the house.,It's no problem to wear short sleeves.,Running around barefoot.。

The cold in the northeast is a physical attack.,It's basically fine before the wind breaks through the armor.,Once the wind blows through the armor.,It's over.,The next thing is the rhythm of the heart that immediately penetrates the heart.,It's really like a pinprick that can be frozen.。

At that time, the snow had already fallen, and when I went downstairs, the car was gone, all covered by snow, and I couldn't get out, everyone was wearing very thick clothes, wearing hats and masks, and some of them were freezing and didn't dare to go out.

In the early spring, the weather warmed up very quickly, and I took off my autumn pants, but it suddenly cooled down, and it snowed, and when I went out, I was so cold that I doubted my life.

I went to school in Datong, and it was really cold in winter, more than 20 degrees below zero, and the wind blew on my face with a stinging feeling, so we basically didn't go out on Sundays.

After washing the clothes, they were dried outside, and in a minute, they were frozen hard, like ice cubes.

When practicing in Changchun, the coach of the car field poured water on the ground and encountered the air freezing ice.

Not necessarily, it is impossible to determine which day, because the temperature is related to many factors, but the coldest time in northern China generally occurs around the Great Cold Solar Term.

The period from the winter solstice solar term to the "small cold" and "big cold" solar terms will be the coldest period of the year. The "winter solstice" also marks the beginning of the number nine, and the ground receives the least amount of solar heat from the shortest day, but the heat stored by the ground in summer and autumn can be replenished at this time, so the temperature is not necessarily very low. By the time of "39", the heat stored on the ground will be exhausted, as long as the cold air comes, it will be cold, and that is the coldest season.

Winter in Hohhot, minus 38 degrees. Wrapped in three layers of extra-thick clothes, the cold wind can still blow into the bones, and the stinging hurts.

The spit is frozen, almost frozen like a dog, every time I wear it like a pig, but I still can't stretch out my hands. The weather is getting unbearable.

In the winter fishing in Qiqihar, everyone drove their cars to the river, minus 40 degrees, and the ice was as thick as 50 centimeters, and that winter fishing was the coldest weather I had ever experienced. ‍‍

It's 42 degrees here, dripping into ice, and remember to bring a stick when peeing. Needless to say, damn it, I'm still freezing.

It is rumored on the Internet that the lowest temperature of the weather this year will break the record again, and my city is now in the autumn of the four seasons, the autumn is high and cool, although it is a little cold, but it is almost the same as in previous years, and the temperature does not fluctuate too much. Although, it is rumored on the Internet that this year's winter will be a cold winter and no longer a warm winter, the main reason is caused by the La Niña phenomenon. However, experts have refuted rumors about this matter, experts say that although the La Niña phenomenon does exist, it will not have a great impact on our country, and this winter will be the same as in previous years, and the temperature will not fluctuate very much.

The experts' refutation of the rumors has made it clear that this winter will not be an extremely cold winter, of course, whether it is a warm winter or not, experts have not given an accurate statement. La Niña has indeed caused abnormal temperatures in some parts of the world to drop sharply and snow to close the doors. But the latitude we are in, with its four distinct seasons, is largely unaffected by La Niña.

Now it is the late autumn season, the autumn is high and cool, the sun is very good, not very cold, and the body feels very comfortable. Because this year is a leap month, it is said that this year should be colder, but the temperature is still very stable so far, in line with the characteristics of this season. Therefore, the minimum temperature will be broken this winter, and in my opinion, the chances of it happening will not be very high.

Whether the temperature is high or low requires scientific data to speak, not hearsay, and not according to some proverbs. Although the proverb is based on the experience accumulated by the older generation of farmers based on farming, there are also discrepancies. If you want to know whether this year is a warm winter or a cold winter, you still have to pay more attention to the ** of the meteorological station.

According to the meteorological observatory, it is very accurate to do a good job of prevention and preparation.

Although I was looking forward to the winter when the snow was falling and the road was covered with snow. But whether this will happen this winter is still unknown. Most people hope that this winter will still be warm, but in fact, a warm winter is not necessarily good, and it is not a good thing for crops.

It's already starting to get cold where I'm located. I believe that in a few months, it will be colder and colder in Wuhan.

My current location is in the northern region, and the temperature is relatively cold now. Based on personal experience, the temperature this year is a little colder than usual, and it is estimated that the snow may be earlier this year.

The place where I am is is still very warm, basically a shirt is fine, there is no need to worry about how cold it is, and the state is very good.

Why is it cold in winter and hot in summer? Some people may think that we are far away from the sun in winter, and the opposite in summer, but in fact, this idea is completely wrong, the earth revolves around the sun is an ellipse close to a perfect circle, the closest date to the earth is in early January, and the farthest distance is in early July, that is to say, it is precisely when we are closest to the earth that it is the coldest season in the northern hemisphere, which also shows that in the process of the earth orbiting the sun, the distance of the earth from the sun is not a factor that determines the temperature or cold. The correct explanation is this:

The four seasons are formed mainly because the equator and the ecliptic (the path through which the sun travels as seen on Earth) are obliquely intersected. When the Earth moves, the direction of its axis in space does not change. In winter, the sun's rays are obliquely on the ground, and the heating per unit area on the ground is less, and the days are short, and the daily sunlight is short, that is, the heating time is short, and then because of the atmosphere around the earth, it absorbs a part of the light and heat, and when the light is irradiated, the thicker the atmosphere, the more it absorbs, so it causes cold in winter.

In summer, on the other hand, the sun hits the ground directly, the days are long, and the light passes through the atmosphere and is thin, so the climate is hot. The spring and autumn rainy seasons are between winter and summer, so the climate is mild. It is because in winter, the height angle of the sun is smaller, the sunlight is obliquely shining on the earth, the energy density of the sun reaching the earth is smaller, and the earth gets less energy from the sun, so the winter is cold; And in summer, the height angle of the sun is large, the sunlight is almost direct to the earth, the energy density of the sun reaching the earth is very large, and the earth gets more energy from the sun, so the summer is hot.

Because the Earth's orbit around the Sun is an ellipse, in winter, our Earth is closer to the Sun; In the summer, our earth is far from the sun.

Recently, there has been a long period of rain and snow in a large area of China, and some places have shown snow scenes that have not been seen for many years, and heavy snow has affected traffic and vehicles in many areas. The weather continues to be cold, and it has also caused frequent respiratory and cardiovascular diseases, and people generally feel unwell, so they can't help but wonder: Didn't you say that the climate is warming, why did you come to a "cold winter" this year?

This phenomenon has also occurred in previous years. In 2002, after 16 consecutive years of "warm winters", there were several large-scale snowfall processes in the winter, and the average temperature was lower than normal for the same period of the year. This year, the situation is more complicated due to the influence of La Niña, such as the recent cold snap in the Gulf region, which has an average temperature of around 25 degrees Celsius throughout the year, and the minimum temperature dropped to minus 3 degrees Celsius for two consecutive days on January 15 and 16; In the northern part of Saudi Arabia, 10 people have even died due to the cold weather.

Therefore, whether this winter is "warm" or "cold" seems to be a little confusing. In fact, climate is a complex system. This year, there is more rain and snow, the reason is precisely that the warm and humid air is active, and the cold air is not strong enough, and the cold and warm confrontation are difficult to distinguish, which has caused the increase of cold and rainy and snowy weather in a wide range of areas in China.

So, in the final analysis, it is still the climate that is causing the trouble. In the context of global warming, it is not impossible that there will be temporary cooling or even extreme cold weather locally. This is reminiscent of the scene depicted in the American film "The Day After Tomorrow".

The Day After Tomorrow tells the story of the sudden and sharp cooling of Europe and the United States due to global warming, and the ice age. Although the film is fictional, it has a scientific basis. It turns out that global warming has caused a large amount of snow and ice to melt in Greenland and the Arctic, and the balance of the "thermohaline circulation" has been changed by the flow of cold fresh water into the North Atlantic.

The film reminds us that a warming climate can lead to extreme events such as flooding, hailstorms, typhoons, heavy rainstorms, and severe cold. Although we have not yet had a climate disaster similar to the one in "The Day After Tomorrow", this year's widespread continuous rain and snow across the country, as well as the severe haze and fog in the past few days, have sounded the alarm bell for us: we must have a fuller and more complex understanding of the harm caused by climate warming.

Don't think that the global temperature is a few degrees higher, it just makes people warmer. "Warming" is a beast, a ferocity, and a chameleon. Humanity should act now and not let "The Day After Tomorrow" really appear tomorrow, or even today.

Global warming is the main culprit.
