An analytical problem of psychology: knowing the weather by observing things.

All kinds of animals, plants and utensils have different reactions to weather changes, and some of them are very sensitive. When the weather turns rainy, the temperature rises, the humidity increases, the air pressure decreases, and the weather is sultry, they will show abnormal reactions. These reactions can be used as a reference for weather forecast.

"Ants are in the way, 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, there is no wind and it is raining."

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.

"Spiders can make good webs, but their webs are cloudy."

After the rain, the air pressure increases and the humidity decreases. Spiders open their nets to catch insects. Spiders don't weave webs in stormy weather. Therefore, it is possible to predict sunny and cloudy weather by spider web-building and web-building.

"Earthworms are crawling on the road, and the rain is messy.

Crickets sing and the weather is fine. "Earthworms like to make holes in places with low humidity and loose soil, such as excavation activities, which means that there is more water vapor in the air and low air pressure, which is a sign of heavy rain. Lilacs (also known as dragonflies) also make holes in the soil and sing at dusk in summer. The mole's voice shows that there is not much water vapor in the air, which is a sign of sunny days.

"Long wormhole, a sign of rain.

Toads croak, and heavy rain is coming. "Snakes are commonly known as bugs. The snake gallery shows that the humidity in the air increases, the air pressure is low, and the water vapor in the cave is not easy to diffuse and evaporate, so it is sultry and the snake has difficulty breathing. When it comes out of the hole, it can breathe, and it will rain soon. Toads are amphibians. Before the rain, the air pressure was low and there was a lot of water vapor. Frogs cry when they feel that they can't breathe well. Before the thunderstorm, toad called it this way: his voice was not loud, intermittent, big and small, and his voice was hoarse.

"The crow sings late, the wind and rain are not far away, and there is wind on the crow's head."

The crow's head is always against the wind. At night, crows fly around in the sky and croak, indicating that the wind direction in the sky is uncertain, which is a sign of wind and rain in the sky.

"The old cow looked up and sniffed the sky. It's raining. The horse's mouth is facing the sky and it is raining heavily. "

When the weather is about to rain, the water vapor in the air increases and the air pressure is low, so it is difficult for livestock bodies to dissipate heat, and sometimes there is a phenomenon of opening their mouths to dissipate heat from the sky.

"Joint pain, rain or shine. It itches in the morning and the wind blows at night. "

Meteorological factors such as temperature, air pressure and humidity will change greatly before the coming of strong wind and heavy rain. Older people or people with physical injuries are particularly sensitive, and the physical reaction is fatigue or joint pain and itchy scars. This is a manifestation of human activities affected by weather changes. "Hair rings and the wind blows."

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.
