Behavior of small animals before rain

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 very low

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.

3. The spider closed the net curtain

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.

4. Crows sing late

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.

5. The old cow raised her head.

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.
