As we all know, in fact, in our daily life, we often find that such weather changes are really unpredictable, and such extreme weather is also very common in many cases. I believe that everyone has also seen the fact that the rainfall in the south is capped on a large scale on the Internet, so many people will have such a question, that is, why does the southern region suddenly usher in a large-scale rainy weather? For the answer to this question, I think it may be related to an abnormal phenomenon in the air before. Let's take a closer look.

1 is related to solar halo.

I believe that everyone has a certain understanding of solar halo, and everyone knows that this phenomenon is also a very rare phenomenon. At the same time, when this phenomenon appeared in the sky, it really caught our public's attention. We all know that there is an outline and a circle in the sky, and its periphery is very shiny. This means there will be some extreme weather in the future.

Seriously affect people's lives.

As we all know, this rainy weather in the south has something to do with the grass halo in the sky the day before yesterday. In addition, this large-scale rainy weather has seriously affected people's production and life. We can see on the internet that there is such a large range of rainfall in many areas, and the ground is directly covered by deep water, which directly leads to people's travel difficulties and traffic is hindered to a certain extent.

So in our daily life, we should also pay more attention to this problem. For everyone, when we look at the weather forecast, we find that the weather is abnormal. We should take certain preventive measures in advance to avoid some losses in this rainstorm, which will also have a certain impact on our production and life.
