Why is the sandstorm in Xinjiang so big ~ ~

Song Yudong, director of Xinjiang Institute of Ecology and Geography, said recently that according to the monitoring, the dust in Xinjiang was blown to North China, Beijing and even Japan, and even as far away as the United States, and was carried by high-altitude airflow.

According to experts, there are two main sources of dust in China, namely Xinjiang and Inner Mongolia, especially Xinjiang. The Taklimakan Desert in Xinjiang covers an area of 337,000 square kilometers, which is the largest dust source in China. Xinjiang also has one third of the country's desertified land, with little vegetation protection, and it is also the main sandy land in spring.

According to reports, the dust in Shayuan, Xinjiang, rose to about 6 kilometers above sea level and drifted eastward with the westerly circulation in the northern hemisphere. When encountering a large airflow, part of the dust sinks, forming a sandstorm. In recent ten years, the sandstorm area in Central Asia, one of the four largest sandstorm areas in the world, has become the most active area in the world, and Xinjiang sand source plays an important role in it.

At present, this serious ecological problem in Xinjiang has attracted the attention of all countries. Japan and China signed a contract to carry out sandstorm research, mainly to study the geographical conditions, climate conditions, transmission process and influence range of Taklimakan sandstorm, and thus put forward prevention and control countermeasures.

According to Wei Wenshou, chief expert of China, they set up sandstorm monitoring points in Xinjiang, Gansu, Shaanxi, Beijing and Japan. The project lasted for five years, and the Japanese side invested a lot of instruments and equipment. At present, Japanese experts have entered Taklimakan for observation and sampling.
