Affected by the Mongolian cyclone, strong winds and sandy dust appeared again in the northern region! What is the causal relationship between the two?

These two relationships are complementary to each other, that is to say, the cyclone in Mongolia has affected our country, coupled with the severe desertification areas in our country, the two together have caused the current sand and dust weather. ,

1. Sand and dust weather must meet two conditions.

Generally speaking, the following two conditions must be met to produce sand and dust weather. The first condition is desertification in the area. It is more serious. The vegetation has been damaged and has no ability to resist sand and dust weather. The second condition is to encounter strong airflow.

I take the sandstorm that occurred in Mongolia as an example. It has already survived. Seriously, when strong airflow enters my country's Inner Mongolia, Northeast, and North and Central China, and desertification is more severe in some places in my country, sand and dust weather appears again in the northern region.

2. Severe desertification comes first, followed by stronger airflow.

Sand and dust weather must meet these two conditions. If one of these two conditions is not met, it is difficult to cause sand and dust weather. The greening of some areas It's done very well. There are basically no desertification areas. When this area encounters strong air currents or strong winds of level 7 to 9, it is just strong winds and will not cause natural disasters such as sand and dust.

But for some areas with severe desertification, such as the Loess Plateau and Inner Mongolia, even if they encounter not very strong airflow, sand and dust weather can still occur. People living there must close their windows. If the windows are not closed properly, it only takes a day to find a layer of soil in the house. These are potential sand and dust weather.

3. Sand and dust weather is a natural weather.

We need to understand one thing. Sand and dust weather is a kind of natural weather, which means that no matter how we protect the ecological environment, it may cause sand and dust weather. It cannot completely disappear, but we You can reduce the frequency and frequency of its occurrence through your own efforts. For example, converting farmland into forests and grasslands. In some areas with severe desertification, using useless straw straws inserted into the desert can also effectively prevent sand and dust weather to a certain extent. To prevent sandstorms,

4. We must take self-protection measures when encountering sandstorms.

In addition to knowing the impact of sandstorms and the conditions that cause them, we must also Take self-protection measures and try not to go out when encountering sandy weather. If you must go out, be sure to wear a protective hat, goggles, and two layers of masks to prevent sand and dust from entering your nose, because Sand and dust entering the nose is likely to cause upper respiratory tract infection.

Secondly, do not drive a private car out. Sand and dust weather can easily cause traffic accidents.
