Who is the animal meteorologist?

1, spider weather forecast method:

On rainy days, if the air pressure increases and the humidity decreases, insects fly high and spiders open their nets to catch them, which indicates that the weather will clear up. On the contrary, the spider closes its net, which indicates that it will rain. As the saying goes, "spiders weave webs, and after the rain, it clears up."

2, frog weather forecast method:

In spring and summer, frogs cry loudly and densely, which indicates that it will rain soon. The proverb says, "When a toad shouts, it must be raining heavily".

3, ant weather forecast method:

Ants came out of the hole in droves, which indicated that heavy rain was coming. As the saying goes, "ants are in droves, and tomorrow will not be sunny."

4, chicken weather forecast method:

Before it rains, the air pressure is low and the humidity is high. Insects fly very close to the ground, and chickens want to find food for insects. Besides, the cage is so stuffy that chickens don't want to go in. As the saying goes, "chickens are worried about the rain, ducks are worried about the wind."

5, dragonfly weather forecast method:

If you fly up and down in the air, there will be heavy rain in about 2 hours.

6, magpie weather forecast method:

Magpies are auspicious birds in our country. According to scholars' research, the degree of magpie nesting is related to the annual rainfall. For example, magpies nest in high places, and it rains a lot all the year round. If magpies nest in low-lying areas, it means that there is little rain all the year round.

7, pig weather forecast method:

The sow lazily pulled open the feed and arched all over the floor, indicating that the sunny weather is about to turn cloudy.

In nature, some animals constantly adapt to the changes of the environment in order to survive, and are sensitive to some weather changes in the long-term evolution process. Animals that can predict weather changes are called "animal meteorologists".

8, termites forecast weather method:

In spring and summer, when the weather is sultry, termites will fly out of the cave. I didn't know the way back to the cave at night, so I jumped at the light, which indicated that it would rain heavily or thunderstorm in a day or two.

9, cats and dogs weather forecast method:

"Dogs wash their faces, cats eat grass, and it rains in less than three days"; "Dogs bite grass, cats bite grass and rain"; "The dog is lying in a pile of ash, and it is raining." In addition, if the cat buries its nose in fur, it also indicates that there is a cold current coming from the north.

10, chicken weather forecast method:

When a chicken climbs high, it will shine. Another expert believes that the sleeping posture of domestic chickens is also related to the weather. If the head of a chicken sleeps outside, the weather will be fine; If the head of a chicken sleeps in, it will become rainy and rainy; If the head of a chicken is nothing more than nothing, the weather will be gloomy.

Example 1

Jellyfish can capture the information of the coming storm before 10 ~ 15 hours, and calmly hide their bodies in a safe place. Bioengineers have found that jellyfish have an "ear" that can feel ultrasonic waves. There is a thin rod at the front end, and there is a ball filled with liquid inside, on which a small stone floats, which is in contact with nerve endings. When the balls receive ultrasonic waves, they transmit them to the nerves through pebbles, and jellyfish know that strong winds are coming.

Example 2

Another kind of loach is called "barometer". On sunny days, it is motionless under the water, and when it is windy and rainy, it will curl up and swim. It may rain soon when it flies up and down in the water.

Example 3

In the animal kingdom, frogs are called "living barometer", which is caused by the characteristics of frog skin. When the air is dry, the evaporation of skin moisture is accelerated, so frogs must stay in the water to keep their skin moist; In the wet and rainy season, the skin moisture does not volatilize and jumps out of the water. Therefore, frogs have become a "living barometer" for African aborigines to observe weather changes. As long as the locals see the tree frog climb from the water to the tree, they will do a good job of rain protection.

Example 4

1794 In the early winter, the French army invaded the Netherlands. Unable to fight, the Dutch had to open the canal gate and try to flood the road with water to stop the French attack. Facing the huge flood, the French army is ready to go home. At this time, the commander of the French army, who knew a little about biology, found that the spider turned the net abnormally, but he urgently ordered the troops to stop acting and stand by. Because he knows that spiders only do this in sunny and cold weather. Sure enough, the temperature suddenly dropped soon, the water soon froze, and the French army went straight into the ice cave. It was the spider's barometer that helped the French army a lot.

So far, humans can't predict the weather very accurately, but there are many "barometers", "hygrometers" and "thermometers" on animals ... These living instruments are very sensitive to all changes in the atmosphere. People have used it in real life since ancient times.

There are many marine animals in the animal kingdom, and they have the ability to observe storms. Based on many observations, bioengineers found that jellyfish is a highly accurate "barometer". It is found that jellyfish have "ears" that can sense ultrasonic waves, and their "ears" can clearly hear the ultrasonic waves coming from the water within 10 to 15 hours before the storm. According to the working principle of jellyfish "ears", scientists have made an "electronic ear" device to automatically forecast strong winds, which can forecast more than 10 hours in advance.
