How did the forecaster of the Meteorological Observatory introduce the self-stop dust in Qinling Mountains?

Experts pointed out that it is not the Qinling Mountains that block the dust themselves, which is related to the direction of air flow. The direction of airflow is a process of east road transportation, so it has little impact on Hanzhong.

Sandstorms have reduced the air quality in many areas and become seriously polluted areas. However, although many cities have been affected by the dusty weather, the air has been seriously polluted and become a seriously polluted city. However, only the air quality in Hanzhong is excellent. After a light rain, the air in Hanzhong City has become fresher.

The Qin Mausoleum blocked the dust by its own efforts.

When sandstorms raged, the air in Hanzhong was really fresh. Netizens guessed that it would be the Qinling Mountains north of Hanzhong, and stopped the sandstorm from going south by themselves. Zhu Min Street, Hantai District, Hanzhong City, Shaanxi Province and Liangshan, Nanzheng District, which are more than 10 kilometers away, are faintly visible with high air visibility. So some people say that the Qinling Mountains in Hanzhong area have blocked the quicksand and dusty weather at the bottom of the atmosphere and will not affect Hanzhong area. For a time, Qinling stopped the dust from going south by its own efforts, and went on a hot search, which ushered in the praise of netizens in the south.

The expert gave a professional explanation.

For this sandstorm that ravaged many areas, let the air quality in these areas? Floating red? Only Hanzhong has fresh air and good quality. So some people speculated that Qinling stopped the dust by its own efforts. However, meteorologists pointed out that this statement is not accurate because it is related to the direction of airflow. This time, the airflow direction is an eastward movement process. Although the Qinling Mountains blocked some of the wind, because of the wind direction, the Qinling Mountains had little influence on Hanzhong itself. The expert's explanation broke the argument that Qinling stopped dust on its own. So some things can't be based on your own subjective assumptions and guesses. You must listen to the experts.

We should take protective measures in the face of sandstorm.

The arrival of sandstorm will bring us a lot of inconvenience and reduce the air quality. Therefore, for some people with respiratory diseases, it is recommended not to go out, especially some old people and children. Close the doors and windows at home to prevent sandstorms from causing some old respiratory diseases. If you have to go out, you should also take protective measures, put on protective clothing, protective mask and protective glasses. Stay away from trees and some outdoor billboards, so as not to be hurt by fallen trees, fallen billboards and other objects. And don't ride a bike. In sandstorms, accidents are easy to happen because of low visibility and strong wind.
