There is also a wide range of dusty weather in the north. Why is there frequent dust this year?
Up to now, there have been five large-scale sandstorms in China this year, among which the northwest sandstorm from June 5438+04 to June 5438+05 was the strongest sandstorm in China in recent 10 years, and the scope of sandstorm was also the widest in recent 10 years. Faced with this situation, many northern friends can't help but feel uneasy: Why is there so much dusty weather this year? Is the sandstorm family going to return to the Jianghu again? ?
What is the reason for frequent sandstorms this year? Zhang Juan, an analyst with China Weather Network, said that since the middle and late February, many places in the north have been unusually warm, while the warm range of sand source areas in the central and western Inner Mongolia is rare in the same period. The soil thawed ahead of time, and the precipitation continued to be less. A similar situation has occurred in Mongolia, so under the influence of strong winds brought by Mongolian cyclones and cold air, dust weather processes will occur frequently.
In addition, March and April of each year are the time periods with frequent sandstorms. In addition, the temperature rose rapidly this spring, and the soil was thawed and loosened in advance. As long as cold air passes by, it is easy to blow up the floating soil on the soil surface and form dusty weather. Therefore, in the face of frequent dusty weather, don't worry, just pay attention to protection.
Dust weather is very harmful to human body outdoors. Fine sand particles inhaled into the body are easy to cause respiratory diseases, and blowing on the face will also cause great harm to human skin. Therefore, in dusty weather, the public should minimize outdoor activities, and if they need to go out, it is best to wear masks and take sand prevention measures.
