Examples of phenological phenomena

When the weather changes, everything on the ground, including animals and plants, should feel its influence. Therefore, this special life phenomenon of animals and plants caused by weather changes can help us know the future changes of the weather in advance if it appears before our human feelings about weather changes.

* When ants move, it will rain. (Zhengding and Xingtai, Hebei)

* An ant nest, there must be a flood. (Guangdong)

* When ants build defensive roads, there will be heavy rain. (Guangdong)

* The urn is wearing a skirt and it rains heavily. (Linzi, Shandong)

* Water tank pillar sweating, rain. (Guangdong)

* The salt pot is still wet, so rain is inevitable. (Yiwu, Zhejiang)

It is a phenomenon that too much water vapor in the air condenses on the cylinder wall. Wearing a hat on the mountain is a phenomenon that low clouds drown to the top of the mountain in frontal cyclone. Clouds move closer to the mountain, and because of the uplift of the terrain, clouds often cover the top of the mountain. The reason of the snake passage is the same as that of ants moving, because it is wet and the air is turbid, so you have to "go out".

* Earthworms are on the road, and it rains when they go out. (Guangdong)

Earthworms are in the way, and it will rain in less than three days. (Guangdong)

Because earthworms have no special respiratory organs, they breathe on the skin. The oxygen in the soil first dissolves in the mucus on the skin surface, then penetrates into the skin and then enters the capillaries. When the soil is too wet, the air in the soil decreases, which will affect the normal "breathing" of earthworms. Therefore, when it is about to rain or after the rain, earthworms are often seen crawling out of the ground.

* Grasshoppers come out early, and they all say that grasshoppers are roes. (Cang County, Hebei Province)

The grasshopper is a kind of locust. Its eggs are laid in soil, and it is easy to colonize when the weather is dry and the dry land is dry. Fish eggs are born in water, and big water is suitable for fish growth. When the soil is too wet, the air in the soil decreases, which will affect the normal "breathing" of earthworms. Therefore, when it is about to rain or after the rain, earthworms are often seen crawling out of the ground.

It is said that grasshoppers are fish eggs when they are dry and fish when they are drowned. (Cang County, Hebei Province)

The grasshopper is a kind of locust. Its eggs are laid in the soil, and it is easy to reproduce when the land is dry. Eggs are born in water, which is suitable for fish growth.

Dragonflies fly low, either wind or rain. (Yiwu, Zhejiang)

Before the rain, the air humidity was high, and the wings of flies, mosquitoes and other insects were stained with water, which increased their weight and made them unable to fly high. In order to catch these insects, dragonflies also fly very low and hover.

* Swallows fly low and it's going to rain. (Hebei)

Before it rains, the wind is strong and the agitation is fierce, so the swallows can only fly low. Besides, insects don't fly very high before it rains, so finches chasing insects have to fly very low in order to get food.

* The chickens return early and the weather is fine; The chicken came back late, and the rain is coming. (Guangdong)

Domestic chickens like to be dry. Before it rains, the water vapor is thick, and the chicken cage is particularly humid and sultry, so they don't want to enter the cage early.

* Spiders add silk, and the sky clears up. (Yiwu, Zhejiang, Wuxi, Jiangsu)

Spiders make a living by catching small flying insects. They are particularly sensitive to air humidity. On cloudy days, the air is wet and heavy, and the spider Netease is wet and sticky, so it is difficult to catch bugs. As the weather improved, the air humidity gradually decreased, and spiders began to stir, busy adding silk and netting to catch small flying insects.
