“The bees go out of the nest and the weather is fine.” “The bees don’t work, the heavy rain is coming.” “The bees bring rain and the honey will be fine.” These proverbs are about the bees’ ability to predict the weather. The front and rear wings of the bees are very thin and light, and they are used to flying in clear weather and high air pressure. Before the rain, due to the increase of atmospheric water content, high humidity and low pressure, the bees are easy to get on the fine water droplets, the weight gains, the wings become soft and heavy, and the frequency of the flaps slows down, which makes the flight difficult. Stay out of the hive. In the morning, if a large number of bees rush to fly out of the beehive, it may be a big sunny day; if the bees don’t go out of the box, get out of the box, or leave the beehive, it will indicate that there will be rainy weather.
Jellyfish can capture the information of the storm 10 to 15 hours ago, and calmly hide the body in a safe place, because the jellyfish has an “ear” that can feel the ultrasound. On the ocean, infrasound waves (frequency 8 to 13 times per second) caused by air and wave friction are the preludes to the storm. This infrasound is invisible to the human ear, but the little jellyfish is very sensitive. Inside the jellyfish ear, there is a very small listening stone. It is the infrasound wave that vibrates the stone. The stone listens to the vibration of the infrasound wave to the nerve receptor in the ear wall of the jellyfish. The jellyfish can hear the storm sound. Since the infrasonic wave travels much faster than the storm and the waves, the jellyfish can receive the “pre-announcement” of the storm in advance and quickly take evasive measures. The bionics modeled the jellyfish ear storm predictor according to the structure and function of the jellyfish ear, which is of great significance to the safety of navigation and fishery.
In the animal kingdom, frogs are called “live barometers”, which are caused by the characteristics of frog skin. When the air is dry, the skin moisture evaporates faster, and the frog has to stay in the water to keep the skin moist. In the wet and rainy weather, including the eve of the rain, when the air moisture is high, the skin moisture is not volatile, and the frog will jump out of the water and scream. Some indigenous people in Africa use the tree frogs to understand the weather. If the locals see the tree frog crawling from the water to the tree, they will do the rain protection work.
Sparrows are sensitive to weather changes. In the winter, if you find that the sparrows are looking around, they are flying all the time. When they enter the nest, they still have weeds, seeds and the like in their mouths. This indicates that the sparrows are hoarding food, and it will snow in 3 to 5 days. In summer and autumn, the weather is hot and the air is humid. The sparrow feels itchy and flies to the shallow water to take a shower. This situation will indicate that there will be rain in a day or two. If a large group of sparrows take a bath, there will be heavy rain in the future, so the folks say: “The group of birds are cold, and the rain is big and strong.”
“Look at spiders and know the weather.” Although spiders are small animals that are not well-known, they have played a key role in historical military events. In the summer of 1940, Hitler developed the “Eagle Plan”, trying to bomb the British factory with heavy fog, and the United Kingdom will be at a disadvantage in the fog. On August 15th, the German army began to bomb. On this day, the British army learned from the phenomenon that a large number of local spiders spun silk nets that the weather would be better and the fog would be exhausted. So they prepared for the battle and soon they will most of the Germans. The bomber was shot down and Hitler’s “Eagle Plan” went bankrupt.
Pansy is a common wildflower species in Europe. Its leaves are very interesting. They can measure the temperature as a thermometer, so they are called “temperature grass.” Its blades are extremely sensitive to temperature. When the temperature is above 20 °C, the blades extend obliquely upwards. If the temperature drops to 15 °C, the blades slowly move downward until they are parallel to the ground; when the temperature drops to 10 °C At the same time, the blade protrudes obliquely downward; if the temperature rises, the blade returns to its original state. People can know the temperature according to the direction in which their blades extend.
In the summer, the willow leaves sag and sway with the wind as a kind of scenery, but if the willows turn white, it is predicted that the rainy weather will come. A closer look reveals that instead of the willows turning white, the willows will all reverse before the rainy days, while the opposite side of the willows will be light green with a layer of “white frost” on the surface.
“There is a lot of rain in the water, and there is a lot of rain.” This is because the temperature plummeted before the rain, and the pressure on the pond surface decreased, causing the moss at the bottom of the river to surface.
Touching the mimosa with your hand, its leaves will shrink. If the contraction is slow or the leaves are closed, they will open immediately, indicating that it is about to rain. If it is quickly closed, it will be restored for a long time, indicating that it will be clear.
The top of the pumpkin vine usually grows slowly toward the bottom. If the top of the pumpkin vine is generally upwards in the summer morning, it indicates that the weather will turn from sunny to rain; if it is found in the rainy weather, the top of the pumpkin vine is common. Looking down, it indicates that the weather will turn fine.
