There is sand blowing or floating dust in provinces and regions. What is the defense policy?

Dust is a weather phenomenon, which is mainly divided into floating dust, sand blowing, sandstorm and strong sandstorm.

In recent days, China has issued many sandstorm warnings. The sandstorm on March 15 was the strongest sandstorm weather process in China in recent 10 years, and the scope of sandstorm was also the widest in recent 10 years.

According to the latest news, sand blowing or floating dust appears in six provinces of China, so what is the defense policy? Dust is a weather phenomenon, which is mainly divided into floating dust, sand blowing, sandstorm and strong sandstorm.

According to the latest news, sand blowing or floating dust appears in six provinces of China, so what is the defense policy? Let's take a look with Bian Xiao.

One or six provinces have sand or floating dust.

According to the website of the Central Meteorological Observatory, the Central Meteorological Observatory continued to issue a blue warning of sandstorms on March 08 18.

Affected by cold air and strong winds, it is estimated that there will be sand blowing or floating dust in western Inner Mongolia, eastern Xinjiang and southern Xinjiang basin, northwestern and eastern Qinghai, north-central Gansu, Ningxia and northwestern Shaanxi from 20: 00 on March 8 to 20: 00 on March 9, among which there will be sandstorms in parts of western Inner Mongolia and southern Xinjiang basin.

The latest research results of China National Environmental Monitoring Center show that around 19, the dust pollution belt stranded in the central and eastern parts of northwest China is expected to gradually ease due to the influence of large-scale systematic precipitation from west to east. At the same time, a new round of cold air will affect the northern part of China from west to east, and there will be a strong northwest wind around the 20th. Beijing-Tianjin-Hebei and its surrounding areas are at risk of dust or sand blowing, and the concentration of PM 10 may be 0.

Second, what is the defense policy?

1, prepare for wind and sand prevention, and close the doors and windows in time;

2. Pay attention to carrying dust-proof articles such as masks and scarves when traveling to avoid dust from causing certain damage to eyes and respiratory tract, and be sure to seal the precision instruments;

3. Pay attention to building boards, scaffolding, temporary structures, etc. that are easily blown by the wind, and properly arrange outdoor items that are easily affected by sandstorms;

As the visibility is low, the driver should control the speed to ensure safety.

5. Minimize going out. If you have to go out because of need, you should pay attention to slow down when driving and cycling, and try to avoid cycling.
