Dust storm weather
A new round of dusty weather is ushered in the north. With the arrival of spring, dusty weather is also ushered in the north. Prior to this, the northern part of China experienced a dusty weather. The dusty weather in the north is inseparable from the climate. The northern region is closely related to the eastward movement of the upper trough and weak cold air, and the dusty weather generally only affects the northern region of China. Affected by the Mongolian cyclone, sandstorms will occur in Inner Mongolia, Gansu, Xinjiang, Beijing, Liaoning and Shandong in northern China on the 26th, and sandstorms will occur in some areas, and the dusty weather will last for at least two days. This sandstorm is the same as last time in Lu Jing, but the intensity is obviously weaker than last time.
The reason for the new round of dusty weather this year is more obvious than in previous years. Although spring is a season with frequent sandstorms, it is directly related to the temperature rise this year. Since the end of February this year, the temperature in the northern region has become unusually warm, the soil has thawed earlier than in previous years, and the precipitation is less than in previous years. The same is true of Mongolia in the north of China. The soil thaws, the temperature rises, there is no precipitation, and the bare plants on the surface have not yet grown. The prevailing westerly winds swept across the northern part of China along with the Mongolian cyclone, which brought the same dust as the cold air.
The reason for the continuous sandstorm weather in northern China In recent years, sandstorms have always appeared in northern China. The main reasons are as follows:
Due to deforestation, the vegetation coverage in northern China is low, especially in the upper reaches of the Yellow River. There are deserts in the north of China, especially in Xinjiang and Gansu, which provide sufficient raw materials for sandstorms. In winter and spring in northern China, there is no vegetation on the surface, and the exposed soil on the surface has little resistance to wind. In addition, the precipitation and windy weather in northern China are prone to sandstorms. At present, the vegetation coverage rate in northern China is gradually increasing, and the effect of wind prevention and sand control is getting better and better. I believe that sandstorms in northern China will improve in the future.
