< p>The weather has been unpredictable recently. Weather forecast has become an important information that people rely on in their lives. Without advanced instruments and equipment, humans would be far behind animals and plants in predicting and sensing the weather.

For animals and plants in nature, in order to survive, the organs in the body will gradually adapt to changes in the external environment; this "adaptability" is inherited from generation to generation, forming a response to changes in the external environment. Perceptual abilities. Among them, some animals and plants can show unique responses before weather changes, which can predict whether it will be warm or cold or sunny or rainy.

■Weather forecast competition, cattle farms won the Weather Bureau

The United States held a special event in the 1990s The weather forecast competition was conducted between the Houston Weather Bureau, which has modern equipment such as weather satellites, radars, and computers, and a cattle ranch that only owns cattle. The cattle ranch won, with a score of 39 to 61. Of course, such results are accidental and unlikely to occur often.

Cows and sheep are often compared. Cows can predict the weather, and sheep are no exception. The great scientist Newton once heard a shepherd say that it was going to rain, and he expressed doubts because the weather was unusually sunny at the time. But within half an hour, it started to rain heavily. Newton was so amazed that he went to ask for advice. The shepherd said that the sheep is a "living hygrometer". If it likes to lie under the eaves, it will rain; if the sheep jumps on the grass, it will be sunny.

Frogs are called "living barometers" in the animal kingdom. When the air is dry, the moisture in the frog's skin evaporates faster, and the frog will naturally stay in the water (to keep the skin moist); and in humid and rainy seasons, including when there is more moisture in the air before rain, the frog will jump out of the water. Because of this, as soon as the indigenous residents of Africa see tree frogs climbing from the water to the trees, they begin to take some measures to prevent rain and moisture.

The sparrow is the "least precious" among birds, but it is "sensitive" to weather changes. In winter, if you find sparrows looking for food everywhere, flying non-stop, and carrying weeds, seeds and other things in their mouths when they enter the nest, it means that the sparrows are hoarding food. Generally, it will snow in 3-5 days. . In summer and autumn, the weather is hot and the air is humid. When sparrows feel itchy, they fly to shallow water to take a bath to dissipate heat. This situation will indicate rain within a day or two; if a large group of sparrows take a bath, there will be heavy rain in the future. An old folk proverb goes: " The birds are cooling off, and the rain is heavy and strong."

Spiders are also small animals with an inconspicuous appearance, but military strategists in history like to "look at spider webs and measure the weather"! In the summer of 1940, Hitler formulated the "Eagle Plan" in an attempt to use the foggy weather to bomb large British factories. The tall chimneys protruding above the sea of ??fog were targets for German bombing, and British aircraft were bound to fight in foggy weather. unfavorable. On August 15, the German army began bombing, but it was on this day that the British army learned from the phenomenon of local spiders spinning a large number of silks and webs that the weather would get better and the fog would clear, so they prepared for battle and soon Most of the German bombers were quickly shot down, and Hitler's "Eagle Plan" was completely bankrupt.

The chipmunk lives in cold Siberia and can also predict the weather. On a sunny day, if the chipmunk makes a shrill scream and scurries back and forth, it means that dark clouds will soon cover the sky and heavy rain is coming; if the chipmunk screams loudly in the morning, it means that around the evening There will be bad weather.

■Plants also know whether it is cloudy or sunny

In the summer, the willow leaves droop and sway with the wind, which is a kind of scenery; but if you find the willow leaves turn white, it is a sign of danger. Rainy weather will come. In fact, if you observe carefully, you will find that it is not that the willow leaves turn white, but that the willow leaves will all turn over before rainy days, and the reverse side of the willow leaves is light green, with a layer of "hoar frost" on the surface. If you are interested, you may wish to observe and verify it before and after rainy days in summer and autumn.

The tops of pumpkin vines usually grow slowly downward. However, if you find that the tops of pumpkin vines are generally pointing upward on a summer morning, it indicates that the weather will turn from sunny to rainy. On the other hand, if you find that the tops of pumpkin vines are generally pointing downward in rainy weather, it indicates that the weather will turn fine.

Peach bamboo is a plant in southern my country that grows bamboo shoots every year. When the bamboo shoots grow in the middle of the mother bamboo (commonly known as "the mother holds her baby"), it indicates that the winter of that year will be colder; conversely, when the bamboo shoots grow outside the mother bamboo (commonly known as "the mother holds her baby"), it means that the winter will be colder. It indicates that the winter of that year will be warmer.

Mimosa is very strange: if you touch it, its leaves will close up and then hang down, as if shy. Among them, because the degree of "shyness" is different, the predicted weather is also different: if the touched mimosa leaves quickly close and droop, and then it takes a long time to return to their original state, it means that the weather will be bright and sunny. The sun is high and the sky is clear; on the contrary, if the leaves shrink slowly after being touched, droop slowly, or the leaves open after closing for a while, it indicates that wind and rain are coming.
