What is the last sentence that there will be a rainstorm tomorrow?

The last sentence of "There will be heavy rain tomorrow" is that ants move the snake aisle, swallows fly low and fish jump. It is to predict the weather through the abnormal behavior of animals. Because animals need to gradually adapt to the natural environment in natural evolution, they are more sensitive to the natural environment than humans, so they are more sensitive to changes in the external environment and respond more quickly.

The main reason for ants to move is that ants perceive the change of air humidity through tentacles and have an early warning of rain. The main reason for moving is to carry dirt to block the hole and prevent rainwater from pouring into the hole. The snake gallery is because the snake is eager to go back to the cave to shelter from the rain. Usually, snakes will follow a fixed route. Because it is eager to go home, it is not taboo, so it often meets snakes crossing the road on the road. Swallows fly low because the water vapor content in the air is too high, and the wings of small flying insects can't fly high when they touch water vapor. Swallows fly very low on the ground in order to catch small flying insects. Fish jumping out of the water is also a precursor to heavy rain. Before the rainstorm, the air pressure changed greatly, and the lack of oxygen in the water caused the fish to breathe in the water, so it was necessary to get some air on the water.

In fact, in addition to warning the weather, animals are also more sensitive to natural disasters such as volcanoes and earthquakes. Animal hearing is far beyond the frequency range of human hearing, especially when an earthquake occurs, it often produces strong vibration from underground. People can't hear the sound through hundreds of kilometers of soil, but infrasound has strong penetrating power and can penetrate the soil, so cats and dogs with wider hearing frequency range can get information in advance and make corresponding responses.
