According to a press conference held by the General Administration of Emergency Situations of Mongolia on March 15th, on the evening of the 14th, snowstorms and strong sandstorms occurred in many provinces such as Kent, Dongfang, Sukhbaatar, South Gobi, Central Gobi, and Gobi Sumbel in Mongolia. In severe weather, wind speeds can reach 20 meters per second and gusts can reach 30 to 34 meters per second. This caused the most intense and wide-ranging sand and dust weather process in China in the past 10 years.
During the interview, experts told the Global Times that a powerful cyclone in Mongolia lifted the local sand and dust to high altitude, and then, under the effect of the continuous eastward movement to the south, a large amount of sand and dust were transported straight into the eastern part of China. Several meteorological conditions worked together to finally form the strongest sand and dust weather in China in 10 years.
Experts also emphasized that the sand prevention and control projects that China has promoted for many years have played a certain role in reducing sandstorms, and that the root cause of fundamentally preventing sandstorms lies in the source of governance.

Sandstorms cannot be cured. This is mainly related to the overall environment of the earth and the development stage of the earth itself. With the current level of science and technology, humans cannot stop this catastrophic sandstorm. From the perspective of the geographical environment, Mongolia’s location is very special. , Far from the ocean, Mongolia’s easternmost Hatebur is adjacent to my country’s New Barhu Banner. This place is 700 kilometers away from my country’s Bohai Bay in a straight line and 1,000 kilometers from the Sea of ​​Japan. There are Daxing’an Mountains, Yinshan Mountains, Yanshan Mountains, and Changbai Mountains in the middle. The sea breeze You can’t blow this place at all. Therefore, the main precipitation in Mongolia is blown from the Arctic Ocean. Second, Mongolia itself is located in the northern temperate zone. The precipitation in the temperate zone mainly relies on atmospheric circulation. When water vapor cannot approach, precipitation cannot be formed. Without precipitation, there will be no surface evaporation, and there will be no precipitation. This determines that it is very difficult for vegetation to grow here. Third, Mongolia itself has a high altitude. The Mongolian plateau has an average altitude of 1,580 meters, which also prevents the arrival of water vapor to a certain extent. In the entire Mongolia, only the capital, Ulaanbaatar, has a flat terrain along the banks of the Selenga River, with sufficient water, suitable for large-scale human settlements. It is the northern part of Mongolia, the eastern central part. Fourth, Mongolia is controlled by the Siberian cold and high pressure from the north all the year round. Its power is so strong that the hot and humid air in the south can’t blow through. Therefore, this is how the large tracts of Gobi in central and eastern Mongolia came from. Besides, Mongolia’s economic development model is the first. Mongolia’s economic pillar is the mining industry. Mongolia is rich in resources, but its technological level is low and it can only rely on the export of raw materials. Second, half of Mongolia’s population is concentrated in the capital Ulaanbaatar, and the remaining herders are also concentrated in the central and northern regions, because further south is the endless Gobi Desert. In terms of this economic development model and population distribution model, Mongolia has neither the ability to deal with sandstorms nor the intention to deal with it. Let’s talk about the role of windbreak forests. Windbreak forests, as the name implies, conserve water to protect the soil and fix the surface. Therefore, no matter how many types of windbreak forests, they can only reduce the harm of wind and sand and prevent the wind and sand from spreading further, but it cannot control the wind and sand. Human beings are too small for the earth and the universe, and people can’t stand a gust of wind on the surface. It has been the same since ancient times. The Great Wall cannot withstand foreign enemies. Therefore, no matter how many trees our country can plant, it cannot withstand disasters from the earth itself. International cooperation is particularly important. The community of human destiny is not something that anyone can choose to join or not to join.

If the sandstorm can be controlled 100%, where will the Loess Plateau be?

As long as there are deserts, sandstorms are inevitable.

Afforestation cannot eliminate the natural desert, but can only reverse the “desertification” phenomenon at the edge of the desert.

Therefore, people can only weaken the dust storm a little bit at most, and it is impossible to eradicate it, and there is no need to shout some bold words.

​Sand control “failed to stop the strongest sandstorm in 10 years”? Expert: It has played a weakening role. Putting an end to sandstorms is fundamentally at the source. A strong sandstorm sweeps across most parts of northern China, causing China’s most intense and widest sandstorm process in the past 10 years. During the interview, experts told the Global Times that a powerful cyclone in Mongolia lifted the local sand and dust to high altitudes. Then, under the effect of the continuous eastward movement and southward airflow, a large amount of sand and dust were transported straight into the eastern part of China. Several meteorological conditions worked together to finally form the strongest sand and dust weather in China in 10 years. Experts also emphasized that the sand prevention and control projects that China has promoted for many years have played a certain role in reducing sandstorms, and the root cause of preventing sandstorms from the root lies in the source of governance. Three conditions have created the strongest sandstorm in 10 years Wang Gengchen, a researcher at the Institute of Atmospheric Physics of the Chinese Academy of Sciences, said in an interview with a reporter from the Global Times that three conditions must be met for the formation of a sandstorm, namely sand source, cyclone and smooth movement. The sand and dust weather affected 12 provinces and cities in northern China from west to east. The Central Meteorological Observatory upgraded the sand and dust storm warning from blue to yellow on the 15th. The State Forestry Administration released information on the 15th. Based on a comprehensive assessment of satellite imagery and ground monitoring information, the dust originated in southwestern Mongolia and then moved south with the airflow. It entered at the junction of Mongolia and the central and western parts of Inner Mongolia on the evening of the 14th. Within China. According to information from a press conference held by the General Administration of Emergency Situations of Mongolia on March 15th, on the evening of the 14th, snowstorms and strong dust occurred in many provinces such as Kent, Dongfang, Sukhbaatar, South Gobi, Central Gobi, and Gobi Sumbel in Mongolia. In severe weather, the wind speed can reach 20 meters per second and gusts can reach 30 to 34 meters per second. Wang Gengchen said that the local blizzards and windy weather in Mongolia are a manifestation of the strong Mongolian cyclone. The Central Meteorological Observatory indicated that the Mongolian cyclone was developing strongly, and the central pressure reached 980 hPa at 2 o’clock on the 15th. It is precisely because of the powerful cyclone that a large amount of sand and dust in Mongolia has been drawn into the high altitude. Wang Gengchen analyzed that the strong cyclone not only means that the amount of dust involved is increasing, but the height of the dust being lifted into the air has reached at least 10 kilometers. “Without a cyclone, sand and dust cannot be carried to high altitudes, but can only move on the surface; but if there is no continuous high air flow, sand and dust will not be transported over long distances and will settle quickly. The higher the dust rise, It will blow farther.” Wang Gengchen said that the sand and dust caught in the high wind experienced continuous cold and high pressure moving eastward and southward, eventually transporting the sand and dust to Beijing and other places. Expert: It does not mean that this intense sandstorm will occur every year. Wang Gengchen said that the source of China’s sandstorm is in the north, northwest, and western regions, involving Mongolia, Central Asian countries, and China’s Inner Mongolia and Xinjiang. However, Central Asia and Xinjiang are far from the eastern region, and the national defense and sand-fixing work between Canada and China is effective. Therefore, the sand and dust from the west will hardly affect the eastern region. On the contrary, because of the close distance, the dust from Inner Mongolia or Mongolia can still spread to eastern China. Chen Guangting, a researcher at the Cold and Arid Regions Environmental and Engineering Research Institute of the Chinese Academy of Sciences, told the Global Times in an interview that according to statistics, about half of the sand and dust weather in China comes from sand and dust in Mongolia. Wang Gengchen said that China has not experienced such a wide and intense sandstorm this time in 10 years. It is the result of the combined action of several meteorological conditions. But this does not mean that these several meteorological conditions work together to be a normal state, nor does it mean that this kind of sandstorm weather occurs every year. Ren Guoyu, chief expert on climate change at the China National Climate Center, analyzed in an interview with the Global Times, “China’s Xinjiang, Inner Mongolia and other northwestern regions, as well as some areas in Mongolia, are the source areas of sand and dust. The precipitation in these areas has been long-term. It seems that it has been increasing, but the short-term situation is difficult to say, because some years will also encounter winter and spring droughts, which may cause sandstorms to reappear. For example, from 2000 to 2002, there were several very strong Sandstorms.” Putting an end to sandstorms is the source of governance. The strongest sandstorms that have not been seen in 10 years have appeared in northern China. What is the role of China’s ongoing sandstorm prevention and control projects in resisting sandstorms? Wang Gengchen believes that the desertification prevention and control project still played a role in weakening the dust storm. He said that China’s continuous advancement of sand control projects has made the frequency of encountering sand and dust weather less and less in recent years. “Nowadays, people rarely see sandstorms. Sometimes they only see floating dust in spring. This is a manifestation of the role of China’s sand control and sand fixation projects.” Ren Guoyu also held this view. He said that northern China has built construction. Many shelter forests, for example, the “Three North” shelter forests have carried out ecological civilization construction and ecological restoration, and the vegetation of the Loess Plateau is also growing. “This year’s sandstorm is mainly a natural phenomenon. China is working hard to build shelter forests, and the effect is obvious. In recent years, the situation has actually improved. The frequency of sandstorms is much less than that of earlier times. Whether it is on a millennium scale or a decades scale, it is declining.” But he also analyzed this. The improvement of surface vegetation is still limited to a small area, a large area is still in a semi-arid area, and the desert area is still very large. He said that the effect of the shelterbelt is to reduce the amount of local sand and dust in the shelterbelt area, which has an inhibitory effect on the local blowing sand. However, there will still be “sand” in places where afforestation is not possible, such as deserts and Gobi. If the material in the dusty weather is not from the local area, but from the sand and dust transported from a distance, it is difficult to achieve good results. Chen Guangting told the “Global Times” reporter that through research, it was found that the control of sand and dust weather only relying on partial control will not achieve fundamental results. Because the research results show that half of the source of sand and dust weather is imported from abroad. Therefore, the fundamental problem of preventing sand and dust weather lies in solving the problem of sand sources, which involves cooperation in global environmental governance, rather than relying on China’s sand control and sand prevention projects. Chen Guangting said, “It’s not that we manage our own place well, so we won’t be affected by sandstorms, it’s not like this.” Ren Guoyu said that after all, shelterbelts are not a controlling factor. The real controlling factor is nature. “God doesn’t give face, mainly because of human activities.” Wang Gengchen also said that preventing the occurrence of sand and dust weather lies at the source of governance.

The sandstorm on March 15, 2021 is a reminder to us. One, a reminder about the concept of a community with a shared future for mankind. Sand control is not only a problem for our country, but also for our region and the entire planet. When we are immersed in the great success of China’s poverty alleviation and the great achievements of green mountains and green mountains, we should also remember this: the principle of dialectics says that everything is connected; the destiny of people is also the same. China may have been lifted out of poverty, but the people of our neighboring countries are still struggling in poverty. Mongolia is located inland, with low level of civilization development, traffic congestion, backward medical education and poor people. Long-term overgrazing and extensive mining have led to the degradation of pastures and the expansion of deserts, which triggered the 3.15 East Asian sandstorm. In the face of global plagues and meteorological disasters, the virus does not distinguish between skin colors and sand and dust, and is not picky about nationality. No matter how good a country’s self-governance is, sometimes it cannot stand alone in such global events, and it may be hurt by the negligence of other countries. To deal with this kind of crisis, it is necessary for all mankind in the world to coordinate organically. Unless everyone knows that they must face and overcome these disasters, the pain will not leave us. The times call for people to unite and work together on a regional and global level. The world is vast and colorful, and people are closely related to each other. But to this day, there are still many people who claim to be superior, or immersed in the glorious visions of the past, or self-reliant soldiers and will bully the weak; they are always good at accusing perpetrators, but they have never thought about their past crimes and current responsibilities. . The virus plays a prelude, and the old world will eventually be buried. On the other hand, based on China’s work experience in poverty alleviation and development in the whole village and targeted poverty alleviation, in December 2016, the Poverty Alleviation Office of the State Council of China and the China International Poverty Alleviation Center promoted the implementation of the [East Asia Poverty Reduction Demonstration Cooperation Technical Assistance Project]. A number of village-level poverty reduction demonstrations have been launched; these projects have effectively solved the urgent problems of the local people and have become a demonstration and exchange base for learning the most advanced poverty reduction models in the world. They are widely enjoyed internationally, especially in Asian, African and Latin American countries. Attention and reputation. The horn of poverty alleviation is sounded, and a new world is coming soon. I personally hope that China’s governance experience can move from China to friendly neighbors, and then from friendly neighbors to the world. If the people of Mongolia can escape poverty and green mountains, it will not only lead them to a good life, but also protect us from sand and dust. humankind has only one Earth, each nation coexist in one world. Mankind lives in the same global village, and has increasingly become a community of destiny in which you are in me and you are in me. The destiny of mankind is closely linked, and we need to join hands to fight the plague, disasters and poverty, and move towards a better tomorrow.

The idea of this question is a bit strange. The source of this sandstorm is Outer Mongolia. What can we do? In recent years, we have made great efforts to prevent and control sand in China. An example is that large-scale sandstorms have been rare in recent years. Even if we plant every inch of land in China into forests, we will still be affected by another sandstorm like this in Outer Mongolia, but the affected area will be smaller. What can we do? Is it possible to learn from Lei Feng to help Outer Mongolia control sand? Do not make jokes!

We should always be vigilant against the BBC gang. This sandstorm has given them another chance to cheer. Yesterday, they removed the filter of the camera, pressed the shutter excitedly, and took photos that could be exchanged for rewards. They do not care about the source of this sandstorm, nor do they care about the source of this sandstorm. Mongolia has already caused 6 deaths and 80 missing, but they are staring at the sky of Beijing. To hack China, I really broke my heart.

This dust storm has affected the sleep of our people. At about six in the morning, I should have been asleep because I was about to get up in an hour and a half. Young people, the more sleepy you get in the morning, the better your sleep. Suddenly I was awakened by the sound of building a house. Normally, I would continue to sleep in this situation, but today I opened my eyes. Now, I saw the dusk. So I woke up, watched for five more seconds, yellow, and continued to sleep. There is an air purifier in my house. However, when I was about to fall asleep, my teammate who used to slept with me like a pig, usually couldn’t be beaten by thunder, so he got up and watched, watched, and woke me up. As a result, my sleep was shortened by half an hour, and I felt angry when I got up. There is sand in the ears. The air smells of sandy soil. The words are earthy. The topic. Three North Shelterbelt. The planning of the Three Norths project starts in 1978 and ends in 2050, and the current phase 2021-2050 is the third phase. The “Three Norths” Shelterbelt System extends from Bin County in Heilongjiang in the east, to the Uzbel Pass in Xinjiang in the west, to the northern border in the north, along the southern coastal rivers, Yongding River, Fenhe, Weihe, Taohe lower reaches, Karakoram Mountains, including Xinjiang 559 counties (banners, districts, cities) in 13 provinces, cities, and autonomous regions, including Qinghai, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Hebei, Liaoning, Jilin, Heilongjiang, Beijing, and Tianjin, with a total area of ​​4.069 million square kilometers , Accounting for 42.4% of China’s land area. From 1979 to 2050, it took 73 years and was divided into three phases and seven phases. The planned afforestation was 535 million mu. By 2050, the forest coverage rate in the Three Norths will increase from 5.05% in 1979 to 14.95%. This can be regarded as a large national long-term planning level. But local governments also have corresponding protections, such as the Shaan-Gan-Ning Green Belt. What we are doing can only solve the desertification within our country. The source is still in Mongolia. The leaders of this country don’t even think about the situation as they are today. If it doesn’t work, divide it into districts and assign them to China’s provinces. The 70-year plan will give you the whole plan. Are you afraid that the sheep will not be fat and the horses will not be strong? Going early on the road to socialism, desertification does not exist! We are also worrying about it, and we are scattered, and we need to wipe the seat when we go home and ride a shared bicycle.

“The wind going down the Mongolian Plateau, what should be written?” (Jay Chou’s “Dragon Fist”) In the past two days, “the wind going down the Mongolian Plateau” has caused heated discussions. “Beijing suffered the worst sandstorm in the past ten years” has become a domestic issue. In the headlines of major foreign media, the term “sandstorm”, which has gradually faded out of people’s vision, was brought up again. Some foreign media and netizens took the opportunity to criticize China’s environmental protection policies, and the Ministry of Foreign Affairs also slammed back “China is not the source, and there is no air pollution problem.” national boundaries”. First of all, I have to say that some people confuse sandstorms and smog. Although they are both air pollution incidents, there is a fundamental difference between sandstorms and smog incidents. The sources of smog are diverse, such as industrial sewage and automobile exhaust. However, in strong winds, smog can often “smoke and disperse”, while sandstorms are different, and their occurrence must be accompanied by windy weather. Our country’s air pollution control and tree planting have reduced smog and sandy weather in recent years, so many people are more likely to confuse the two. Smog can be said to be a by-product of economic development, but what about sandstorms? Compared with the man-made interference such as smog, is the sandstorm a “natural disaster” or a “man-made disaster”? Why is there no “spring breeze for ten miles” in March in the north, but “a hundred miles of sand and dust” instead?
Most of the sandstorms in the north are the product of natural atmospheric circulation and a specific underlying surface, and they have existed in ancient times. For example, the earliest record of sandstorms in Beijing can be traced back to the reign of Emperor Taiping Zhenjun of the Northern Wei Dynasty (440 AD) [1]. I say most of them because there are still some exceptions that “man is sure to conquer the sky”, and these exceptions do not directly cause sandstorms, but can exacerbate their scale. For example, my country’s unreasonable exploitation of resources before the 1970s aggravated the frequency of sandstorms. At that time, the nearest source of sand to Beijing was Chengde, which was only 180 kilometers away. Another example is Mongolia, the source of this sandstorm. Due to its long-standing problems of illegal coal mining and overgrazing, the surface of the sandy land is soft and the vegetation cover is little. It is an inexhaustible source of sand and dust. So why do you say that human interference will not directly cause sandstorms?
The formation of sandstorms requires three basic elements: sand dust, strong winds and unstable air turbulence. Human activities can expand the source of sand, but the formation of meteorological conditions is determined by the special geographical location of Eurasia. The weather is cold in autumn and winter, and the smaller specific heat capacity of the land causes the Eurasian continent to cool faster than the Pacific. Therefore, the lower atmosphere in contact with the land is also cooler than the lower atmosphere, forming from the cold north (high pressure) to the warm south (low pressure) The moving mass of cold air, the Mongolia-Siberian cold high pressure. As the world’s largest continent, the sea route difference between Eurasia and the Pacific is particularly obvious. However, because northern China is also very cold in winter, the heavier cold air is not easy to form “air instability conditions”, so there are fewer sandstorms in winter. In spring, as the sun’s direct rays move northward, the northern part of our country warms up. The warm air and the strong cold air going southward in Mongolia “cross” and form extremely unstable air conditions, and sandstorms follow.

There is nothing to do. Natural disasters are not man-made. Appeals and suggestions are not acceptable. Donation of saplings is not acceptable. Planting trees means reducing the area of pastures. Don’t think that Outer Mongolia has a large area and is a grassland. The place where grazing is possible is Mongolia. To the south, bordering us, this is the root of the sandstorm. Mongolia is full of mountains to the north and rich in water and grass in the central and eastern regions. In spring, these pastures are the origin of the sandstorm. Planting trees here is equivalent to a direct collapse of Mongolia.

I don’t even bother to answer this kind of question. What is going south from Mongolia? The situation in the northwestern part of the country is very good. However, the root cause of China’s sandstorm is indeed not in the country, and it has nothing to do with man-made, it is a problem of the natural environment. The warm and humid Atlantic air blows across the Eurasian continent from west to east. Europe is very warm and humid, and Central Asia is very dry and there are many sandy soils. When the wind blows, it is naturally carried to China. The Loess Plateau is actually an accumulation-type plateau. There is more than one Loess Plateau in China. There are also topography of sand accumulation at the junction of the Taihang Mountains, Daxinganling and Qilaotu Mountains. When the wind blows over, there will be sand and soil accumulation, it’s that simple. And because of the existence of the Arctic, the warm and humid Atlantic air currents are more windy in winter, so just planting trees in Central Asia is not enough. You have to plant trees in Europe in winter. Because as long as there is bare sand on the surface, it will be blown to China by the wind. Let Europe, Central Asia, and the Great Northwest have green trees all year round. Think about it, how unrealistic it is. Therefore, planting trees in Dafa is basically equivalent to dreaming.

This wave of multinational express delivery in Mongolia has a great impact on our country. Obvious sand and dust weather has appeared in 12 northern provinces of my country. This is the biggest sandstorm in 10 years! How serious this sandstorm is, go directly to the video. The video was shot on March 15 in Tianjin. The prevention and control measures against sandstorms are mainly the construction of the Three North Shelterbelt Project. The Three Norths Shelterbelt Project began in 1979, and the Three Norths include: Northeast, Northwest and North China. The planned construction period took 73 years, involving 559 counties in 13 northern provinces, with a total area of 4.069 million square kilometers. By 2020, my country has completed 301,400 square kilometers. The main function of the shelter forest is to prevent and fix the local sand, increase the humidity, reduce the wind force through vegetation cover, and prevent the local sand and dust from being drawn into the air by the airflow to form large-scale sand and dust. That is to say, no matter how good our shelter forest is built, it will not solve the sandstorm in Mongolia. This time it was a transnational crime, and the role of the shelterbelt in foreign dust was very limited. Sandstorms are a global problem, and neighbouring countries need to work together!
