What kind of scenes appear in the sky, which will make human beings extremely panic?

Panic is a state of human and biological psychological activities; Usually called an emotion, it refers to a person's psychological state when facing a dangerous situation, and often refers to being scared. Throughout nature and real life, there are many things that make human panic, but when we look up at the sky, what kind of scenes will make human panic?

1. Sandstorm Sandstorm is the general name of sandstorm and sandstorm, and it is a sign of desertification, which mainly occurs in winter and spring in semi-arid and arid areas.

It refers to a weather phenomenon that strong winds roll up a lot of dust on the ground, making the horizontal visibility less than 1 km. It has the characteristics of suddenness and short duration, with low probability of occurrence, but great harm.

Among them, sandstorm refers to a sand-laden storm formed by strong wind blowing a large amount of sand near the stratum; Sandstorm is a storm formed by strong winds, which brings a lot of dust and other particles into the sky.

Soil wind erosion is the primary link in the occurrence and development of sandstorms, and the direct driving force of soil wind erosion is wind. Before the sandstorm came, we could see a black sandstorm blowing in the direction of the wind, moving as fast as a wall and towering as a mountain.

If there is a strong sandstorm, when the wind is above 8, the strong wind will roll up stones and sand at the same time. As more and more dust flies into the air, it will gather together, blocking the sun, causing a dim scene all over the sky, making people unable to see anything for a while, and day is like night.

In addition, the dust on the wall of sandstorm is thin, fine and small, and the sunlight can almost penetrate through the dust, so it turns yellow and red. The dust in the lower layer has a large concentration, coarse particles and large volume, and the sunlight is almost completely absorbed or scattered by the dust, so it is black.

Where the sand wall has moved, the sky is flickering and changing. 20 15 Mali * * * and high, the whole sky has never been red, the visibility is only a few meters, and the atmosphere is cold, giving people a feeling of depression and panic.

2. Tornado Tornado is a rare local, small-scale and sudden strong convective weather. It is a strong and small-scale air vortex caused by air convection movement under strong and unstable weather conditions.

Tornadoes are common in tropical and temperate regions, including Western Australia, the interior of the United States, and the northeastern part of the Indian Peninsula. The common occurrence time is spring and summer, and it is most common in the afternoon to evening.

Before the tornado came, the sky was often thunderous, stormy and dark. Tornadoes are often accompanied by strong winds such as typhoons. In China, typhoons often occur in the southeast coastal areas, even at sea. Like sandstorm, it lasts for a short time, but the harm is very great and unpredictable.

When a tornado happens, it will cause trees to be uprooted and cars to blow straight, which will make human beings extremely panic.

Third, the locust plague refers to the catastrophe caused by locusts that mainly feed on gramineous plants. Its main performance is that a large number of locusts gather together, devour grain and destroy agricultural products. Why are locusts so destructive?

On the one hand, locusts have the habit of living in groups and have strong reproductive ability. When the climate is dry, the soil becomes more solid, the water content decreases, and locusts lay eggs in the soil, which leads to the rapid reproduction and growth of locusts, and because the eggs are deeply hidden in the ground, it is difficult to be eliminated.

Secondly, locusts are omnivorous. Not picky about food? You can eat many kinds of plants. On the other hand, locusts fly fast and have strong flying ability, which is difficult to control. When locusts gather to prey on crops, the sky is dark, like a big net, covering the sky, and it is dark. Isn't that scary?

4. Giant UFO UFO is the Chinese meaning of English UFO. This word comes from the United States Air Force? Blue Book Project? In ancient China, UFO was also called Star Tea.

UFO phenomenon can be roughly divided into four categories: misunderstanding of known phenomena, unknown natural phenomena, unknown natural creatures and flying saucers of alien civilization. Humans often pay attention to the flying saucer of alien civilization, which is the product of high civilization outside the earth.

Since the late 1940s, the number of UFO sightings has increased dramatically, which has caused a debate in the scientific community. Many scientists hold a negative attitude towards this, thinking that UFOs do not exist, but people's illusion or eyewitness's misinterpretation of natural phenomena, and the reason for the misinterpretation is a speculation based on the inability to understand what is observed and make judgments.

Up to now, the debate about UFO continues, and the official has not given an explanation, and there is no official proof of the existence of outer space civilization. But imagine how human beings would feel if a huge UFO suddenly appeared in the sky. Curiosity or panic?

From various case reports, when UFOs are small, people are curious, but when UFOs are large, people will feel extremely scared.

In a word, the sight in the sky will do great harm to human beings, make them helpless, or make them feel extremely scared when they can't explain it.
