National weather Mongolia cyclone

These two relations complement each other, that is to say, the cyclone in Mongolia has affected our country, and the desertification area in our country is more serious, which adds up to the current dusty weather.

1, dusty weather must meet two conditions,

Generally speaking, there are two situations that can produce dusty weather. 1 The condition is that the desertification in this area is serious, the vegetation has been destroyed, and there is no ability to resist dust weather. The second condition is strong airflow.

I take the sandstorm in Mongolia as an example, which is quite serious in itself. When strong airflow enters Inner Mongolia, Northeast China, North China and Central China, coupled with serious desertification in some parts of China, dusty weather reappears in northern China.

2. There is serious desertification in front and strong airflow in the back.

Dust weather must meet these two conditions. If these two conditions are not met, it will be difficult to cause dusty weather. In some areas of our country, the greening is very good and there is basically no desertification. When this area encounters strong airflow or strong winds of magnitude 7-9, it is simply windy and will not cause natural disasters such as dusty weather.

But for some areas with serious desertification, such as the Loess Plateau and Inner Mongolia, even if there is no strong airflow, it can still produce dusty weather. People who live there must close the windows. If the windows are not properly closed, it only takes one day to find a layer of soil in the house. These are all potential dusty weather.

3. Dust weather is a kind of natural weather.

We have to understand one thing, that is to say, no matter how we protect the ecological environment, it may cause sandstorm, and it can't disappear completely, but we can reduce its frequency and frequency through our own efforts. For example, in some areas with serious desertification, returning farmland to forests and grasslands and inserting useless straws in the desert can also effectively prevent sandstorms and dust storms to some extent.

4. In case of dusty weather, you must take self-protection measures.

In addition to understanding the influence and conditions of dusty weather, we should also take self-protection measures and try not to go out in dusty weather. If we have to go out, we must wear protective hats, goggles and two-layer masks to prevent dust from entering the nose, because dust entering the nose is likely to cause upper respiratory tract infection.

Secondly, don't drive a private car out, dusty weather is easy to cause traffic accidents.
