Causes of sandstorms in Beijing

Question 1: What are the reasons for frequent sandstorms in Beijing? , close to the northwest region, as well as terrain and climate factors

Question 2: Why are the sandstorms in Beijing applauded? People in Beijing always feel good about themselves and feel that they are in the capital and have an extraordinary status. They look down on outsiders. In the previous few When there was a sandstorm last year, Beijing was not affected, which made some people feel self-inflated. The capital city is good, and its ecological management is awesome. Even if the ear scraper doesn’t slap you in the face, you won’t know the pain. The Northwest is suffering from sandstorms all year round, and no one pays attention to it even after calling for generations. Now I pay more attention to it. After eating hundreds of thousands of tons of sand, I know what it feels like. I have begun to feel pain. I have begun to "severely question" and be "highly vigilant". Okay, great, we should applaud this sandstorm in Beijing. See China report on April 22, 2006. Sandstorms are flying all over the sky these days. According to statistics from relevant departments, this year's sandstorm is relatively rare in recent years. Throughout the spring, there were only a few good days with warm spring flowers and flowers. Either the temperature dropped, or there were sandstorms, especially in the north. On April 18, 300,000 tons of soil fell in Beijing, creating an unprecedented sandstorm. As people in the northwest who have been tortured by sandstorms, I applaud the fact that there is such a big sandstorm in the capital of Beijing! The reasons are as follows: Reason 1: It can expose the true lies of some departments. In the spring of the past few years, the number of sandstorms in our country has decreased sharply. Especially last year, there were only a few moderate sandstorms and basically no sandstorms were seen in Beijing. Therefore, some departments came out to show their merits and sing praises, saying that the country's ecological governance has achieved practical results, saying that several green forest belts for sand prevention have been built around Beijing, how many trees have been planted, how many forests have been created, and how much greening has been achieved across the country. Land, sandstorms have been reduced to a great extent. In fact, it is obvious that my country's ecological environment is deteriorating rapidly. It is ridiculous logic to boast that ecological governance has achieved effective results after only one or two years without any sandstorms. For example, our Yulin City, on the one hand, is engaged in desert control. Every year it organizes a large amount of manpower and material resources to plant trees and prevent and control desertification. It has become a national model area for desert control and has also created several nationally famous desert control heroes. On the other hand, in order to develop the economy, natural resources are blindly exploited, destroying the ecological environment, indiscriminately digging, draining, and mining, and the groundwater system has been seriously damaged. Some of the original rivers have become sewage rivers, and some have dried up. China The water level of Hongjiannao, the largest desert freshwater lake, drops every year. Without paying attention to comprehensive environmental management, environmental protection, and treating both the symptoms and root causes, what is the use of just planting trees? Even if the trees were planted, they would die of drought. The same goes for the country, which only cares about mobilizing the masses to plant trees every year, only falsifies figures, plants dead trees, and brags about political achievements, regardless of survival rates, actual benefits, and does not change the concept of comprehensive management. It only relies on afforestation figures to say how good the ecology is and how great political achievements are. To some extent, this is all a lie. Because a severe sandstorm destroyed all the beautiful lies, and the "real numbers" that reflected political achievements did not contain the sandstorm. Reason two: It allows Beijing’s officials and citizens to experience the bitter consequences of environmental degradation. People in the northwest suffer from sandstorms all year round. Generations of people have asked the country to attach great importance to environmental issues, especially to increase efforts to control the desert and ecological environment in the northwest. But the slogan has been shouted for many years, but it never attracts enough attention. Sandstorms cannot hit Beijing, and senior officials do not feel the importance and urgency of protecting the ecological environment and regulating the environment. Fortunately, this sandstorm is not afraid of the officials in Beijing. It enters Beijing as soon as it blows, blows through the ***, and drops a layer of soil on the leaders and cars. But this may be a good thing for the people of the northwest! Because if sandstorms blow to Beijing every day like these two days, that would be great. Then it would attract the direct attention of the Communist Party. Then the people's problems would be solved faster and faster, and the people's lives would become better and better. . Reason three: It scrapes out corruption and sadness. Even if the sandstorm doesn't blow, we don't know how great the country's ecological governance achievements will be. Just look at the sandstorms flying all over the sky, and you can see how much of the country's ecological management funds have been embezzled and put into personal pockets; how much of the money has been used for image projects and political achievement projects. Relevant departments have to ask themselves in good conscience: How much money has been actually spent on ecological and environmental governance, and how much actual governance results have been achieved? Why is it that while money continues to be invested, the sandstorms get bigger and bigger? In fact, ordinary people have a clear understanding in their hearts: on the one hand, the originally small amount of special funds for ecological management has been withheld by relevant departments at all levels, and then in the hands of ordinary people, very little money is actually spent on environmental governance, and the special funds have become The pretense of some corrupt cadres asking for money has also become an important source of cadre corruption. On the other hand, the special funds for ecological management are far behind the government's administrative expenses. It is reported that the annual consumption of public transportation and public funds for food and drink account for 4% of the national fiscal revenue... >>

Question 3: Why are there so many sandstorms in Beijing? Regarding the source of sandstorms in Beijing, there are generally three opinions in the academic community:

In situ sandstorms, it is believed that the main source of sand in Beijing is local, and part of the dust comes from other places. In the mid-1980s, scientific researchers measured the content of heavy minerals and unstable minerals in the sand in the Beijing area. The results showed that there was a big difference with the sand and gravel in the Horqin Sandy Land, Hunshandake Sandy Land, and Mu Us Sandy Land, and it was different from the Yongding Sandy Land. Rivers and other local river valleys are relatively close to gravel.

It is believed that the sand in the Beijing sandstorm originated from other places, especially the Bashang area in Hebei, the middle and ancient areas of Inner Mongolia, the northwestern Shanxi area, the Yulin area in northern Shaanxi, and even southeastern Mongolia and eastern Kazakhstan. . In early 2002, the State Environmental Protection Administration's research team on the impact of sandstorms and yellow sand on atmospheric particulate matter in Beijing announced that it had initially identified the source area and transmission path of Beijing's sandstorms. Most sandstorms in Beijing come from overseas source areas. There are three transmission routes for sandstorms into Beijing: North Road, Northwest Road, and West Road.

The opinion of composite origin is that the dust in the Beijing sandstorm comes from both local and foreign sources, that is, the initial source is the Mongolian Plateau and the desert Gobi area on the path of the cold vortex, and the subsequent source is * ** Dusty areas around Beijing.

Question 4: The main reasons for the formation of sandstorms “Abundant dust sources, strong winds and extremely unstable atmosphere are the three indispensable factors that cause sandstorms. The latter two are mainly related to meteorological conditions. The former is related to land desertification. Therefore, although land desertification is not the main factor causing sandstorms and their changes, it is an important factor, and we must not ignore the control of land desertification. "?

Haha, sandstorm expert Qian Zhengan also made mistakes sometimes? ! !

There is no doubt that the cause of sandstorms is desertification of the land! ! There is a ridiculous statement: "Although desertification of land is not the main factor causing sandstorms and their changes"! !

Can you still blame the air flow? Extremely desolate. Air movement is a phenomenon of nature. And land desertification is man-made. It is caused by our current wrong practices: grassland desertification and land desertification. In the past, cattle and sheep were seen in the windblown grass, now it has become quicksand everywhere. Mistakes are mistakes. Don't hide them. If you don't change, it will bring irreparable disaster to future generations.

It also shows the current level of “experts”.

Question 5: Beijing is still very green, why are there sandstorms? Don’t just look inside the city, but also look around.

Question 6: Why is there so much sand and dust in Beijing? Qiao Lin, director of the Beijing Meteorological Observatory, said that there are two main reasons why this sandstorm hit Beijing again 13 years later: On the one hand, before the sandstorm occurred, the upstream areas of Beijing, including Mongolia, Inner Mongolia and other large cities, Sandstorms have broken out in some areas. Sandstorms have a wide range of influence and are strong in intensity. Strong sandstorms have occurred in many areas. On the other hand, the strong winds formed by the intersection of strong cold air and warm air masses this time were stronger. Strong winds of magnitude 6 or 7 appeared in the Beijing area, with gusts reaching magnitude 9. This is conducive to the strong winds transporting more sand and dust to Beijing.

So if you really have to go out in this weather, wear a mask. I can recommend one imported from the United States - Puweixin. Available on JD.com!

Question 7: Why does Beijing have sandstorms in spring? This starts with the conditions for the occurrence of sandstorms:

1. There is a source of sand, 2. Strong enough wind, 3. Dry season, 4. For Beijing, there must be a suitable wind direction.

Why do Beijing have so many sandstorms in spring?

Beijing has a temperate monsoon climate, with northwest monsoon in the winter half of the year. In northwest my country, there are large areas of Gobi, desert, and Loess Plateau. Since most of our country has a monsoon climate, there is little precipitation in the winter half of the year, and the northwest wind blows with strong winds. The northwest wind brings the dust in these areas to the east. Therefore, Beijing is prone to sandstorms at this time (spring drought is common at this time)!

Sandstorms can reach as far as the Hawaiian Islands in the Pacific Ocean. . Can you imagine how powerful it is!

Question 10: Why are the sandstorms in Beijing applauded? People in Beijing have always felt good about themselves and their status in the capital. They look down on outsiders. When there were sandstorms in Beijing a few years ago, Beijing was not affected. These people have greatly inflated their egos. The capital is good and the ecological management is awesome.
