Do you want to take an umbrella when it snows? 1 Yes.

Snow is divided into dry snow and wet snow according to the degree of water content. There is almost no moisture in the dry snow, so it is easy to form thick snow when rubbed by hand, which is blown by the wind and flies with the wind. Wet snow contains a lot of water, so it is obvious that there is liquid water in the snow layer, which is easy to attach to the surface of objects and freeze into ice.

When it comes to wet snow, it is easy to get wet clothes and the temperature of the body will drop. Taking an umbrella at this time can effectively solve this problem, so take an umbrella when it snows.

Formation of dry snow and wet snow

Snowflakes are made up of ice crystals, and only when the temperature is below 0℃ will the ice crystals not melt. Because they fall from the sky, the temperature of some snowflakes is always below 0℃ during the falling process, which makes them fall to the ground as snowflakes and become "dry snow".

Sometimes, the temperature in the sky is below 0℃, but when it is close to the ground, it encounters a layer of gas that is not very thick and slightly higher than 0℃. After falling, the snow fell to the ground before it melted completely, so it became semi-melted "wet snow"

The snow in the north is not easy to melt when it accumulates on clothes, and it will fall off when it shakes. It is different when it snows in the south. On snowy days, the temperature is two or three degrees below zero. Sometimes the temperature is even above zero. Snow falls on clothes, melts quickly, and clothes get wet. It is necessary to take an umbrella in the snowy days in the south.

It snows in the south, and the umbrella is accused of being "too melodramatic"

In recent days, it has snowed in many cities in the south. On the street, citizens travel with umbrellas. "It's snowing with such a small amount of snow, so what should we do? If you go for a walk in the north, no matter how heavy the snow is, it is hard to see someone going out with an umbrella! " On the internet, many northerners expressed their feelings about whether to take an umbrella when it snows. Netizen "Fox Xuanxuan" said in surprise: "Of course, you should bring an umbrella when it snows. Isn't it water that falls on your body? " Netizen "The most beautiful Ling Hua" explained: "I have been to the south from the northeast, and now I understand. The snow in the south is like rain. It will melt in a short time, and it will be very wet and cold. Take an umbrella. Snow in the north will not melt, and snow is snow. If you shoot it on your body, it will fall. " In fact, northerners are full of surprises when they see southerners playing umbrellas on snowy days. Netizen "LaVida 2297" said: "Seeing the snow in the south and wanting to open an umbrella, the first feeling is so sentimental. I thought I was playing TV. Later, it was discovered that what exists makes sense. "

The way netizens spend the winter in the two places is very different, with the north showing off in an ostentatious manner and the south shivering.

Careful southerners find that whether northerners and southerners take umbrellas or not has a lot to do with snow. It is said that the snow in the south is different from that in the north. The snow in the south is small in crystallization, and it melts easily when it falls to the ground, unlike the snow in the north. However, the snow in the north has a unique scenery. The heavy snow falls on the bare tree trunk, the earth and the hills, which is very desolate, spectacular and atmospheric. Snow crystals are big and white, and they don't melt easily.

A comparison map circulated on the Internet vividly expresses how northerners and southerners spend the winter. I saw southerners hiding in the thick bed, wearing big hats and carrying thermos bottles, shivering with cold. In contrast, northerners are much more chic: wearing single clothes and pants, sitting in a heated room and eating ice cream. Netizens describe it with pictures-it's the season of "northern students show off in an ostentatious manner and southern students tremble". There is also an explanation circulating on the Internet about the difference between north and south in winter: cold skin in the north and frozen bones in the south. For example, the cold in the north is a physical attack, just wear thick clothes; The cooling in the south is a magical attack. It's no use wearing more clothes. You should be resistant! Some netizens also pointed out the difference between the north and the south: "The anti-freezing device in the north is high, and the anti-freezing performance in the south is high."

Southerners practice "frost resistance" in winter.

Netizen "Mr. Xiao Lei" has lived in both the south and the north, and he is deeply touched. "It is normal to rain in winter in the south. In the north and south of the same season, the plants in the whole city in the south are still full of vitality, but it rained and it was cold. Although the scenery in the north is mostly gray and white, it is dry and clean. " Netizen "What do you believe?" Tucao: "In the winter in the south, the chill has spread all over the body. Dry and cold is not cold, wet and cold is really cold! "

However, when it comes to frost resistance, netizens in the north may be far less powerful than those in the south. There used to be a joke that the heating pipe in a certain section of a city in the north burst, causing the indoor temperature of residents to drop to 17℃. They all said they couldn't stand it. It was too cold. In this regard, the southern netizen "Sydney Orange Shirley" lamented, "It turns out that children in the south are the most frost-resistant!" For the cold in the south, some netizens took advantage of making weather to tell a cold joke: Today, I made a special trip to burn a pot of boiling water and make a cup of hot black tea. It's too hot, so I put it aside to brush Weibo. Without brushing a few, I picked up the teacup-Oh, my God, it's already iced tea!

What are the benefits of snowing?

The advantage of snowing is that it is beneficial to the growth and development of crops. Snow is beneficial to the growth and development of crops. Snow is a kind of material with good thermal insulation effect, which can protect plants from frostbite in cold winter, and the melting of snow water in the next spring can provide a good water source for vegetation. The power of nature is definitely not a coincidence. Because of the poor thermal conductivity of snow, covering the soil surface with a layer of snow can reduce the diffusion of soil heat and block the invasion of cold air on the snow surface. Therefore, crops protected by snow can survive the winter safely. The standard of snowfall grade usually refers to the standard of continuous snowfall or the transformation of snowfall into rainfall within a specified time. This standard generally adopts two standards: duration 12 hours and 24 hours.
