Why do there always be sandstorms in the Northwest?

Due to the sparse vegetation, sandy soil, frequent cold waves and windy weather, coupled with the degradation of grassland and serious land desertification caused by man-made destruction, sandstorms are easy to occur in the spring when the climate is relatively dry

Sand and dust weather concept.

Sand and dust weather is divided into four categories: floating dust, blowing sand, sand and dust storms and strong sand and dust storms.

Floating dust: a weather phenomenon in which dust and fine sand float evenly in the air, making the horizontal visibility less than 10 kilometers;

Blowing sand: a weather phenomenon in which the wind blows dust and sand on the ground, making the air quite turbid, and the horizontal visibility is within 1 km to 10 km;

Sandstorm: A weather phenomenon in which strong winds blow a large amount of dust and sand on the ground, making the air very turbid and the horizontal visibility is less than 1 km;

Strong sandstorm: A weather phenomenon in which high winds blow dust and sand on the ground, making the air very turbid and the horizontal visibility is less than 500 meters.

This is related to the region, this is the same as why there are no plants in the desert, regional factors, lack of water, less vegetation, vegetation has a soil consolidation effect, less map is weathered, into sand, the wind has naturally flown everywhere...

climatic, geographical location and soil quality.

MZMM is afraid of harming the plate.

Recently, there has been a large-scale sandstorm in the northern region, which has brought a lot of inconvenience to people's production, life and travel, and also seriously threatens people's health.

According to experts, the sandstorm weather originated in Mongolia, due to the recent frequent weather changes, affected by the polar cold vortex, coupled with the recent drought and lack of rain, the surface is soft, and the vegetation in some areas is seriously damaged, so as soon as the polar cold air vortex comes, there will be a sandstorm weather.

Therefore, we must take care of the environment, plant trees, fight against desertification, and protect our homeland.

Why is there a sudden sandstorm in the north? What's so strange about this, a natural phenomenon that happens every spring, but to a different extent, like wind, rain, thunder and lightning, the power of nature, human beings have no way to solve it for the time being!

Baptism. Sandstorms are the natural enemies of smog, and they are a killer move. According to the rules of nature, there must be a thing from 1 thing to be restrained in Zen and disgust.

Spring and autumn is the time when strong winds blow. It's normal to have sandstorms. Dust storms are also one of the many climatic phenomena on Earth. He Yuan will travel to the interstellar of mankind in the future. It may be possible to find a more habitable planet without extreme weather.

The frequent occurrence of sand and dust is mainly related to environmental and ecological damage.

1. The weather is becoming more and more extreme now.

The weather in these years has always broken the bottom line and actively melted glaciers. Temperatures of up to 40 in summer and warm in winter are all due to the extreme weather.

In the morning, the sky is still clear, and in the afternoon it becomes a storm, and the environment is becoming more and more unpredictable, which creates a lot of conditions for the dust weather, and the dust weather needs to have two conditions, the first condition is that the desertification of the area is very serious, and the second condition is that there is a strong air flow, if the wind turbine reaches level 7 or 8 or above, it is easy to have dust weather, or even dust storms.

2. The phenomenon of indiscriminate felling is too serious, and animal husbandry is too developed in many places.

Take the sandstorm in Mongolia before, for example, the main reason is that Mongolia's animal husbandry is relatively developed, and many cattle and sheep graze vegetation in herds, resulting in serious local desertification.

3. Typhoons have become more and more frequent in recent years.

One of the conditions for the occurrence of sand and dust weather is to have a strong air flow, if the desertification of the area is too serious, there is no need for a strong air flow to cause sand and dust weather ratio, such as China's Loess Plateau, all year round is a piece of dust, many families if they do not close the window for a day, there will be a layer of ash in the house.

Dust weather is a natural weather, so don't worry too much.

Dust weather is the same as a tornado, both belong to a kind of weather in nature, that is to say, no matter how we protect the environment, dust weather may occur, but we can reduce the frequency of its occurrence through our own efforts, usually in daily life to plant more trees and grass, can not destroy vegetation, try not to pollute the air, pollute the environment, the consequences of polluting the environment, is to make the weather become extreme, once the weather is extreme, it is easy to cause natural meteorological disasters, For example, tornadoes, tsunamis, typhoons, etc.

We must also do a good job of self-protection in dusty weather.

In recent years, sand and dust weather has become more and more frequent, we must not only understand the decision-making of sand and dust weather, but also know how to protect ourselves in the event of sand and dust weather, try not to go out in case of sand and dust weather, if you have to go out, you must wear a hat, wear goggles, wear two layers of masks, and avoid sand from entering the eyes or nasal cavity, <>

In addition, do not drive, the visibility in dust weather is very low, and it is easy to cause traffic accidents.

Because of the invasion of cold air, sandstorm weather occurs in the sandstorm of windy weather carriers, and we must pay attention to precautions.

The main reason is that the environmental protection situation in Northwest China and North China is not particularly good, so there are more sandstorms in these areas.

This is because of the severity of the sandstorms in Mongolia this year, coupled with the low forest vegetation coverage, and the sand and dust are also relatively serious.

The main reason is that it is affected by extreme weather, so it causes sand and dust to appear frequently.

The main reason is that this year's wind is relatively strong, coupled with the pollution of the environment in recent years, and a large number of trees have been cut down, and because of this, it has led to the destruction of the forest and caused a very serious sandstorm.

Because the earth's bearing capacity is limited now, and the environment in many places has been seriously damaged, there have been great changes in temperature and environment.

Because the destruction of trees is causing desertification to approach people and constantly endanger people, which is at people's own fault.

"The smell of spring is mixed with the smell of earth. "Since the beginning of this year, the north of our country has encountered five dust weather processes. According to the forecast, from tomorrow (March 26) to the 28th, there will be a large-scale sand and dust weather process in the north, and Beijing and other northern China regions will be blowing sand or floating dust this weekend, and there will be local sandstorms.

Why is there so much dust this year? China Weather Network analysts answer in detail. The north will welcome a new round of sand and dust weather Beijing's air quality deteriorates on Sunday Today, affected by the eastward movement of the upper-air trough and the eastward movement of weak cold air to the south, the sand and dust weather mainly appeared in the northwest region.

Starting tomorrow, under the influence of the eastward movement of the Mongolian cyclone, there will be a strong sand and dust weather process in northern China. It is expected that tomorrow, there will be sand or floating dust weather in central Inner Mongolia and northern Hebei. This weekend, the scope of sand and dust weather will expand, and there will be sand or floating dust weather in Gansu, Inner Mongolia, Ningxia, Shaanxi, Shanxi, Hebei, Beijing, Tianjin, Liaoning, Shandong and other places, and there will be local sand and dust storms.

Because of the serious global climate change in recent years and the pollution of the environment, in fact, these natural disasters are the earth's punishment for human beings.

Wind erodes soil, destroys vegetation and buries farmland.

Polluting the air. Affect traffic. The impact of sandstorms on traffic is mainly manifested in the following ways: first, reducing visibility and affecting driving and aircraft take-off and landing, and second, sanddust burying roadbeds and obstructing traffic.

Affect the use and production of precision instruments.

Endangering human health.

Cause weather and climate change.

Sandstorms swept North China, what are the hazards of sandstorms to the human body? How to do a good job of personal protection?

This year's sandstorms have been there for many days, but they have not been effectively controlled and spread in areas that are still very extensive, at this time, we will wonder, why this year's sandstorms will not be controlled, even though we are involved in planting trees every year, why is it still so serious? This may have something to do with this year's climate, because the areas affected by the recent sandstorms were relatively hot, and the recent winds have been stronger, which has created good conditions for the sandstorms, so they have not been controlled. <>

Recently, there has been a phenomenon of sand and dust in many places in northern China. Many people question why this kind of bad weather still happens when we plant a large number of trees every year. For this, Bian Xiao guessed that it should be related to the change in weather.

Also, although we plant trees every year, it takes some time for the small trees to grow. Therefore, at present, the saplings cannot withstand the invasion of wind and sand. So sandstorms are still going to happen today.

Why doesn't tree planting mitigate sandstorms? Every spring, many departments and people spontaneously take to the streets to plant trees and protect the environment, but it seems that no good results have been achieved. Efforts have not slowed down the occurrence of dust storms.

In this regard, relevant experts have already known the reasons for the occurrence of sand and dust weather. Experts say that from late February to May, Inner Mongolia is prone to cyclones. This phenomenon creates the conditions for the emergence of dust storms.

The second cause of the dust storm is the generally high temperature in the previous period. Affected by high winds, this creates favorable conditions for the occurrence of sand and dust weather.

It's spring, and everything is slowly starting to recover. So the surface is not covered with a lot of greenery as everyone thinks. Although many branches are starting to spit green, they can't stop the wind and sand at all.

So this kind of severe sandstorm weather has been seen in many places. In fact, afforestation is a public welfare activity that cannot achieve results in a short period of time. If we keep planting trees, we will definitely achieve good results in the future.

Nature is the living environment we rely on for survival, and we should take care of the natural environment at all times, do not litter, do not cut down trees, and do not kill animals. Only when people live in harmony with nature can we create a good ecological environment for ourselves. <>

After this incident, we should be more aware of the importance of planting trees, and we should not cut down a large number of trees, if that is the case, the consequences will be more serious, and it will also bring great inconvenience and threat to future life.

Because a lot of vegetation in the northwest may be cut down, and the ecology has been greatly damaged, and the vegetation may be difficult to survive in sandstorms, it is difficult to control sandstorms.

This year's sandstorms have been uncontrollable to a large extent due to this year's climate, because the areas of the previous sandstorms were relatively hot, and the recent winds have been relatively strong, creating conditions for the continuation of the sandstorms.

Because China's forest resources have been greatly damaged, especially in the northwest and north China, it is difficult to control sandstorms.

In the spring of March and April, it is the season of frequent sand and dust weather, coupled with the warm temperature in the north this year, the loose soil, and the lack of precipitation, coupled with the recent cold air activities are more frequent, if there is a relatively strong sandstorm weather in the upper reaches of Mongolia, it will be transmitted to the downstream areas under the influence of cold air winds, so the northwest region will frequently encounter sandstorms.

Recently, there has been news that sand and dust weather will once again invade northwest and northern China, which has attracted the attention of many people. Everyone is terrified and worried about the coming sandstorm. So what exactly is a sandstorm and how is it formed, in fact, sandstorm is caused by the interaction between sand and wind, and it is also related to factors such as the greenhouse effect, population increase, and vegetation loss.

1. Because there are more and more sandstorms, we should protect our ecological environment. When you go out, try to choose low-carbon travel. Choose to walk, or take a bicycle, subway, etc.

Drive less cars, because the exhaust fumes emitted by cars not only pollute the air, but also create a greenhouse effect that is getting worse and worse. In addition, walking out can also play a role in strengthening the body.

2. Plant more green plants. We all know that the cause of sandstorms is also related to the loss of greenery. Then in normal times, we should plant more trees, flowers and plants.

Because trees and flowers can absorb the carbon dioxide emitted and release oxygen. This not only provides sufficient oxygen, but also purifies the air. It also has an effect on the greenhouse effect and sandstorms.

I believe that if we plant more trees, our air will be cleaner and better. Not only that, but when we plant more greenery, we should also protect the trees, flowers and plants around us. Don't trample on grass, cut down trees, and don't pick flowers.

Otherwise, they will not be able to purify the air without life. In areas where sandstorms are frequent, such as Northwest China and North China, more trees should be planted and car travel should be reduced. I believe that if we do these things, our air quality will be better and better, and our ecological environment will be better and better.

Not only are we surrounded by beautiful flowers, trees, and vegetation, but we also have clear blue skies.
