Find some agricultural proverbs and talk about their phenology.

1, agricultural proverb: fish scale day, no rain, the wind is bumpy.

Phenological knowledge: In the blue sky, you can sometimes see neat and compact white clouds, like fish scales, which are called cirrocumulus in meteorology. Cirrocumulus usually appears at an altitude of more than 5,000 meters, and can only last for a few minutes to more than an hour after its formation.

The appearance of this cloud indicates that a trough of low pressure is approaching over the area. The weather affecting the ground generally depends on the atmospheric movement at high altitude. Therefore, the emergence of cirrocumulus is the time when sunny days turn to rainy days. "It's a fish scale day, and the wind will jump without rain", which is a sign of wind and rain. Usually there will be wind and rain in a day or two. ?

2, farming proverb: it doesn't matter if the sheep are herded in the sky and it rains underground.

Phenological knowledge: "herding sheep in the sky" refers to the white broken and amorphous scattered clouds produced by cumulus clouds in the process of fading, running like driven sheep. This phenomenon mostly occurs in winter and spring. Because the cold air in the north moves south, close to the local area, and the moving speed is fast and the wind is strong, the rainfall is swept away, and there is not much rainfall. Then the local area was controlled by cold and high pressure, and the weather turned fine. ?

3. Agricultural proverb: Spiders can mend nets and the weather will get better.

Phenological knowledge: spiders make a living by catching insects with nets. In windy and rainy weather, cobwebs are often damaged, and at the same time, the air is humid and the viscosity of cobwebs is poor, so it is often difficult to catch insects. So before the storm came, it fled to a safer place. When the wind and rain stopped and the weather was about to clear up, they came out to mend their nets and open them to hunt insects.

So, when you see a spider mending the net and opening it, it indicates that the weather will be fine. ?

4, peasant proverb: frog dreams of pigeons, there is heavy rain.

Phenological knowledge: Frog's skin and organs are very sensitive to weather changes. Before every storm comes, they will gather together and cry loudly. Especially before the thunderstorm weather comes in summer, frogs gather more and more, and their calls become louder and denser. Repeated observation shows that frogs gather in groups, and their calls are loud and close, which always appear before the rainstorm, so they can be used to predict the weather. (Gaspard Monge is Yi language, which means collection).

5. Agricultural proverb: If the moon holds a red umbrella, it will rain heavily tomorrow.

Phenological knowledge: The moon's "holding a red umbrella" refers to a cloudless or partially cloudy night, when the moon wears an obvious red light wheel, which is called "the moon holding a red umbrella". This phenomenon shows that the atmosphere is unstable, the water vapor and dust are obviously increased, and the particles are large, which is a favorable condition for heavy rain, so the moon "holds the red umbrella" is a sign of heavy rain.
