What will be the impact of snowstorm

What will be the impact of blizzard? In the snowstorm weather, a lot of snow is carried by strong wind, and it is impossible to judge whether there is snowfall at that time, and the horizontal visibility is less than 1km. In this environment, people will lose their awareness of the direction, and what will be the impact of blizzard? What will the snowstorm do? 1

Snowstorm weather generally occurs in Inner Mongolia and Xizang Autonomous Region. Judging from the statistics of snowstorms over the years, the meteorological department has analyzed that the possibility of snowstorms in northern China is greater than that in southern China. However, once a snowstorm occurs in southern China, the harm will be much more serious than that in northern China. The south of our country belongs to subtropical monsoon climate, and the temperature in winter is generally above ot, and many agricultural crops are overwintering crops. Under such weather conditions, residents generally don't need heating equipment and heating facilities in their lives, and there are no warm clothes at home. Drivers don't have to worry about the freezing of diesel oil. People are not prepared for the arrival of cold waves and blizzards in advance.

Therefore, when the temperature drops suddenly and a snowstorm strikes, the disasters brought to people are more serious and the losses are incalculable. And people's unconscious and unguarded psychology will contribute to the disaster. The snowstorm did great damage to agriculture. Under the attack of the snowstorm, a large number of overwintering crops can't stand the ravages of the cold wave, many of them are frozen to death, and the agricultural harvest is greatly reduced. In some places, agriculture will even fail, for example, winter wheat, overwintering rape and green manure crops will not safely cross the winter.

In addition to crops, animal husbandry will also be seriously affected, and a large number of livestock will definitely be frozen to death and frostbite. It can be seen that livestock will inevitably be hurt by snowstorms. When a snowstorm comes, strong cooling is accompanied by strong winds, resulting in very low visibility. In this weather, it is very dangerous if the livestock are still scattered outside and have no pens.

it will not only lead to the loss of livestock, but also hurt their lives. According to scientific determination, every kind of livestock will have a limit of life body temperature. When the body temperature cannot be constant and decreases beyond this limit, livestock will face the danger of death. In the environment of low temperature and strong wind, it is difficult to keep the body temperature of livestock constant if the blizzard sweeps again.

This is mainly due to non-evaporative heat dissipation, which makes the thermal regulation in livestock lose balance after a period of time. What will the snowstorm do? 2

A snowstorm is a snowstorm, which refers to the weather phenomenon that a large amount of snow is not falling, but flying by strong winds, and it is impossible to determine whether there is snowfall at that time, and the horizontal visibility is less than 1km. Blizzard is a natural meteorological disaster, which is a general term for heavy precipitation weather below -5℃, accompanied by strong cold air flow phenomenon.

the formation of a snowstorm is similar to that of a storm. Usually, in winter, when the temperature in the cloud is low, the water droplets in the cloud will freeze. When these frozen droplets hit other droplets, these droplets become snow. When they turn into snow, they will continue to collide with other small drops of water or snow. When the snow becomes too heavy, it will fall. Although most snow is harmless, once the wind speed reaches 56 km /h, the temperature will drop below -5℃. If there is a lot of snow at this time, a snowstorm will form.

People often talk about snowfall. When someone says "there was 6 inches of snowfall yesterday", what does it mean? Stepping outside, you may or may not be able to see 6 inches (15 cm) of snow. It is more likely that you find that the snow in some places is only 3 feet (7. 5 cm) thick, but in some places the snow is more than 1 foot (3 cm) deep, and in other places there is no snow at all. So how on earth did people get the figure of 6 inches of snow?

Snow is different from rain. As a liquid, rain flows and cannot be compressed. Even when water is squeezed hard, its quantity will not change. On the open ground, if there is nothing to cover it up, 1 inch (25 mm) of rainfall is the same everywhere. Snow doesn't flow, it starts to accumulate after landing, and the wind blows it to certain places, so the snow in some places is thicker than others. Snow is not the same as snow. Wet snow takes up more space than dry powdery snow. Because there are gaps between dry snow particles, they can be compressed.

It must be pointed out that when we talk about "6 inches of snow", we must also indicate what kind of snow it is and where this depth value was found. Perhaps there is only one way to solve this problem, that is, carefully choose a place to measure the depth of snow, and then consider snowfall as rainfall. This is the job of meteorologists, and the results will tell them more useful information than the amount of snowfall. The data will tell them how much precipitation there is. They collected snow, then melted it, and finally the snowfall they reported was the same amount of rain. There are some differences in this data due to different temperatures. The table shows the snowfall equivalent to rainfall in a certain temperature range. At 29 ~ 34℃ Fahrenheit, the first snowfall is only equal to 1/1 of its depth of water.

In late July, 1977, the snowstorm in Buffalo, USA, was one of the biggest snowstorms so far. Buffalo is located in the snow belt in the east of the Great Lakes in the United States. In most winters, a few feet of snow is common. However, the snowstorm in 1977 was worse than this. The humid wind from Canada has been blowing at a speed of 7MPH(113km/h) for five days, and 4 feet (1.2 meters) of snow has accumulated on the snow that fell 3 feet (.9 meters) a few days earlier. In some places, it is even deeper, with the snow reaching a thickness of 3 feet (9 meters), which is very rare.

when the wind attracts snow, it doesn't mean that the power of the wind will bring us trouble, but the amount of snow brought by the wind will make us afraid. Wind and snow are inseparable. Strong wind can lift snow from the ground and add them to the falling snow team. This is what happened in Buffalo in 1997. A large amount of snow accumulated on the ice of Lake Erie was swept up by strong winds and dumped in Buffalo.

The energy of the wind is decreasing in the process of blowing, and the amount of objects that the wind can carry depends on how much energy it has. At this point, the wind is like a river. A fast-flowing river carries mud, sand and small stones. After a heavy rain, the river will become turbid, because the river carries a lot of mud at this time. When the river slows down and the energy decreases, heavier substances such as stones will sink to the bottom of the river. Rivers can no longer take them away. With the decrease of energy, more and more substances sink, and the heaviest substances sink to the bottom first. Similarly, when the wind loses its energy, the objects it carries will fall down. When the energy of wind-borne snow is lost, the snow will fall down and form thick snow on the ground. What will the snowstorm do? 3

Blizzard, a natural climate disaster. Blizzard, a general term for heavy precipitation weather below -5℃, accompanied by strong cold air flow. A big, nasty snowstorm. It is also a metaphor for a violent political storm.

The main cause of snowstorm

On the one hand, it is a natural law, and the heat and cold of the earth have a certain relationship with solar activity. Every 1 years or so, there is a low tide of solar activity, and the earth will be particularly cold.

on the other hand, as far as the specific situation is concerned, the greenhouse effect slows down the speed of ocean currents due to environmental problems, and it is getting colder and colder in winter.

in addition, it will get hot in some places and sometimes, but it will get cold in other places and sometimes. The greenhouse effect does not mean that the temperature has been rising. In Europe, global warming will be manifested as getting hotter in summer and colder in winter.

What are the hazards of snowstorms

In a snowstorm, a large amount of snow is carried by strong winds, and it is impossible to judge whether there is snowfall at that time, and the horizontal visibility is less than 1km. In such an environment, people will lose their awareness of the direction, and it is very easy to get lost and freeze to death in the wild. When encountering a snowstorm, the herds are terrified, often rushing with the wind because they can't tell the direction clearly, and can't catch up with the circle. They often fall into lake blisters or fall off cliffs, and die and freeze to death. Pregnant female animals run in adversity, which easily leads to mechanical abortion; Some young animals are even addicted to polluted snow or frozen grass, which causes the outbreak of malignant infectious diseases and leads to a sharp increase in the mortality rate of young animals. Blizzard is one of the disastrous weather in animal husbandry production.
