Does the extreme high temperature in Henan indicate that there will be another rainstorm in Henan this summer?

According to the forecast, in July, the rainfall in northern and central Henan is 20% ~ 50% more, and the rainfall in southern Henan is close to the same period of normal years, so it is very likely that there will be a torrential rain. This also reminds us of the rainstorm in Zhengzhou on July 20th, 2 12 1:

In the end, 302 people were killed and 50 people were missing. The affected area of crops 1 0,048.5 thousand hectares, the affected area of crops 1 0,98.2 thousand hectares. There were 57,600 houses with 65,438+800 households collapsed, 46,400 houses were seriously damaged, and 665,438+8,800 houses were generally damaged135,400 households.

This is a very painful experience, which we will never forget. The extreme high temperature this year will definitely cause evaporation and gasification of surface water, especially the Yellow River basin just flows through Henan, and a large amount of river water rises into the air. When it accumulates to a certain amount, it will form rain. As for whether there will be a rainstorm, we have summarized the following signs before the rainstorm. I hope that friends in Henan and the whole country will keep these phenomena in mind and prepare for flood control and self-protection in advance:

1. Always pay attention to the weather forecast, and there will be red, orange and yellow warnings or typhoon warnings before the rainstorm.

2. In hot weather, small clouds suddenly appear, and black clouds are overwhelming, which even makes people feel difficult to breathe. This is usually caused by low-pressure weather, which is often a signal that heavy rainfall is about to happen.

On a hot night, when you hear dull thunder not far away, it is usually a signal that a storm is coming.

In the morning, you can see the formation of pagoda-shaped ink clouds in the distance, and there will be strong thunderstorms in the afternoon.

For several days in a row, the weather was clear and cloudless, especially hot. If you suddenly find that there are small clouds rising on the windward slope of the mountain, there will be a strong thunderstorm at midnight or early morning.

Hearing the dull thunder is usually a sign that a storm is coming.

7. When you see funnel clouds or dragon tail clouds in the sky, it means that the weather is extremely unstable and thunderstorms and strong winds may come at any time.

When we find some warning signs above, we must take the following precautions, and never make fun of our lives:

1. If there are signs of lightning, don't stand in an open place with an umbrella, don't hide under a tree, pay attention to the safety of electricity use and turn off the power in time.

Try to stay at home and don't go to dangerous places, such as hillsides, whirlpools and underground.

With the sudden arrival of the flood, I decided to abandon the car and run to a higher place immediately.

4. Pay attention to water safety after the rainstorm, and don't eat polluted water.

Nature is ruthless, and painful experiences always warn us that it is not too much to take adequate precautions in advance. Finally, I hope this extreme weather disaster will not happen and everything will be safe and smooth.
