How to prevent sandstorms (measures)

Sandstorm is a sudden natural disaster, which poses a serious threat to human life safety and health. Dust weather can cause irritation and injury to people's respiratory system and eyes. The following is how to resist sandstorms compiled by Bian Xiao, hoping to help everyone.

How to defend against sandstorms?

Wear a protective mask: Because the dust particles are large, wearing a mask can reduce the dust particles in the air from entering the respiratory system, and choose a mask that can protect the particles, such as N95 mask.

Wear goggles: Particles in the air in sandstorms can easily irritate eyes, so wearing goggles can protect your eyes.

Indoor shelter from the wind: It is best to stay indoors in dusty weather and close the doors and windows to prevent dust from entering the room. You can turn on the air purifier to purify the indoor air.

Maintain indoor air circulation: doors and windows should be opened indoors and electric fans should be used to ensure smooth indoor air circulation and avoid air pollution.

Pay attention to safety when driving outside: if you have to go out, you should pay attention to driving slowly to avoid driving too fast and ensure your own safety.

Reduce outdoor activities: Sandstorms are more likely to cause respiratory system stimulation, so outdoor activities should be reduced as much as possible, while avoiding strenuous exercise and reducing the burden on the body.

In short, we should pay attention to protect our respiratory system and eyes, reduce going out, stay indoors in dusty weather and keep indoor air circulation.

The sandstorm affected 18 provinces, autonomous regions and municipalities.

The Central Meteorological Observatory continued to issue a blue warning of sandstorms at 06: 00 on June 1 1 day: due to the influence of cold air and strong wind, it is expected that from 8: 00 on June1day to 8: 00 on June 12, southern Xinjiang, most of Inner Mongolia, eastern Gansu, Ningxia, north-central Shaanxi, Shanxi and Ningxia will be affected.

Why is the dusty weather so frequent in the north this year?

According to the forecast, this sandstorm weather process will gradually end around April 1 1, but then there will be another sandstorm weather process from June 13 to June 14, and the northwest, north China and northeast China will be hit by sandstorms again.

This round of sandstorm weather process is the eighth time this year, and the number of sandstorms in the same period of the year is about 5 to 6 times. The number of sandstorms is slightly higher this year. Why is the dusty weather so frequent in the north this year? Meteorologist Wang said:

In terms of climatic conditions, in the early stage, the temperature in the sand source area was high, the precipitation was low, the vegetation had not turned green, and the exposed surface conditions in the sand source area were easy to cause dusty weather.

In terms of weather conditions, since March-April, cold air activity in China is still in an active period. During the influence of cold air, Mongolian cyclone and cold front on the ground become favorable pushers, bringing sand dust from sand sources to downstream areas, and even transporting it all the way to the south and beyond.
