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.
