Proverbs that foreshadow the rain.

The sparrow takes a bath, and rain is coming.

If the chicken is not in the cage, the rain will come.

The carp jumps over the dragon gate, and the heavy rain is sure to pour.

When ants move, it will rain.

As dragonflies rush to the scene, beware of floods.

The swallow flies high and announces a sunny day; the swallow flies low and announces a rainy day.

Snails emerge from the water, and there will be heavy rain soon.

Before it rains, most insects, birds, and some aquatic animals will have special reactions.

Chicken. "The chicken stays late, and the sign is cloudy and rainy." Chickens have no sweat glands and sebaceous glands, and are very afraid of heat due to lack of heat dissipation ability. The ideal temperature for adult chickens is 20°C. When temperatures exceed 30°C, they often open their mouths and extend their wings to help dissipate heat. In the hot summer evening, the chicken coop is even more stuffy, so it is found that the chickens do not want to enter the nest. This is a sign of an upcoming thunderstorm.

Swallow. There is a folk saying that "when swallows fly low, it will rain." This is because swallows eat bugs. When the weather is about to rain, there is a lot of water vapor in the air, which wets the wings of some insects. It is like the plane is overloaded and cannot fly. But if they still want to fly, they can only fly close to the ground. Secondly, when the weather turns cloudy and rainy, the air pressure becomes lower, the water vapor in the air increases, and some small insects in the soil also crawl out of the soil. When swallows fly low to catch insects to eat.
