What are the natural phenomena to predict the weather?

Cows and sheep are often compared. Cows can predict the weather, and sheep are no exception. Newton, a great scientist, once heard a shepherd say that it was going to rain. He was skeptical because it was unusually sunny. But within half an hour, it really rained heavily. Newton was surprised and asked for advice. Shepherds say that sheep are "hygrometers". If it likes to lie under the eaves, it will rain. If the sheep jump on the grass, it will be sunny.

It is called "living barometer" in the animal kingdom. When the air is dry, the frog's skin water evaporates quickly and naturally stays in the water (keeping the skin moist); Frogs will jump out of the water in wet and rainy seasons, including when the air humidity is high before rain. Because of this, as soon as African aborigines saw the tree frog climb from the water to the tree, they began to take some measures to prevent rain and moisture.

Sparrows are the "least precious" birds, but they are the "sensitive person" of weather changes. In winter, if sparrows are found foraging everywhere, flying nonstop, with weeds and seeds in their mouths when they enter the nest, it means sparrows are hoarding food, and it will snow in 3-5 days. In summer and autumn, the weather is sultry and the air is humid. Sparrows feel itchy and fly to shallow water to take a bath to dissipate heat, which will indicate rain in a day or two. If a large group of sparrows take a bath, it will rain heavily in the future, so the folk proverb says, "When sparrows take a bath, it will rain heavily and violently."

Spiders are also ugly little animals, but military strategists in history like to "watch cobwebs and measure the weather"! /kloc-in the summer of 0/940, Hitler made the "Eagle Plan", trying to bomb large British factories in foggy days. The tall chimneys protruding from the sea in foggy days were the targets of German bombing, and foggy days would be unfavorable for British aircraft to join forces. On August 15, the Germans began bombing, but it was on this day that the British learned from the local spider web-forming phenomenon that the weather would improve and the fog would disperse, so they prepared for the battle, and soon shot down most of the German bombers, and Hitler's "Eagle Plan" went bankrupt completely.

Artemisia annua (mainly Artemisia annua and Artemisia ordosica) is a drought-tolerant wild plant of Compositae, which is distributed all over China. If it is found that many tender buds are born at its roots in dry weather, it indicates that it will rain soon.

Ligustrum lucidum is an evergreen tree, and its leaves grow with autumn. If there is an abnormality in summer, there are only fallen leaves and few leaves (or long leaves), as if it is going to sleep in winter, it indicates that there will be rainy weather in autumn in the next 2-3 months, that is, as the saying goes: "Privet Ye Quan falls, and there will be showers in autumn."

Ants in the way? Heavy rain is coming. When ants move, it will rain heavily. " ? Before the rain, there was more water in the air, and the ant nest became wet, which made the ants unable to live peacefully and leave the ant nest. ?

Dragonflies fly low? Rain in No Wind. ? Before the rain, the air pressure was low, and insects mostly floated at low altitude. Dragonflies often fly in the air two or three meters above the ground in order to feed, which is a sign of impending rain.

Hair ringing? It's windy. " ? Comb your hair with a wooden comb, and sometimes it will giggle. This is because the air is dry and the wooden comb rubs your hair to generate static electricity. This kind of situation often happens when strong winds come in spring and autumn. The dry air comes from the northwest of our country, and there is often strong wind in front of it.

Mimosa? This is a very strange plant. Among them, because of the different degree of shyness, the weather is different: if the touched mimosa leaves close and droop quickly, it will take a long time to recover, which means that Wan Li is clear and sunny; On the contrary, the leaves contract slowly after being touched, droop slowly, or open slightly, indicating that the wind and rain are coming. ?
