As the saying goes, it will rain when ants move. How do they know the weather changes?

When the weather gets worse, the water vapor in the air will also increase, the soil will recover moisture, and the ant nest is particularly humid, making it difficult for ants to survive. Animals can predict the humidity of the air. When they think the humidity is too high, they know it's going to rain. Ants are resting underground. Rain will completely flood its nest, so they must move to a higher place.

When ants feel too dry, they know there will be drought, so they will move to wet places. Ants migrate from highlands to lowlands to avoid dehydration and drought. The upland soil has little moisture, which is suitable for ants to settle in rainy days; The lowlands are closer to the groundwater level than the highlands, and they store water every time it rains. In drought, lowlands are wetter than uplands, which is suitable for ants to settle in dry days. The change of weather causes geographical reflection, and the unusual geographical reflection touches the sensitive nerves of animals, and animals observe abnormal actions for a long time. After continuous translation, an agricultural proverb has been formed, which is still of reference value to scientists studying astronomical phenomena.

From the perspective of natural science, the occurrence of natural phenomena will inevitably affect all aspects of nature. As an underground animal, ants, in order to survive, sense that rain is coming, and move their nests to higher and drier areas to avoid disaster. This is a survival skill cultivated by the historical evolution of this species, which is consistent with our human behavior of avoiding danger! We often see this phenomenon. Whenever heavy rain comes, we can see the spectacular scene of ant colony.

Meteorologists use high-tech equipment such as radar, satellites, weather observation stations and supercomputers to predict the weather. Ants also have their own weather "observation equipment", which can accurately judge the weather through the "observation results", make timely decisions and take actions to avoid the tragedy of heavy rain flooding the "nest". The "meteorological observation equipment" of ants is fluff that is very sensitive to temperature and humidity changes. Before it rains, the air humidity and temperature will change, and ants will detect it in time through this accurate "observation instrument" and make a quick decision. If the rain is small and you can't move, they will move if it rains harder and harder. The more it rains, the greater the noise, and they often move in groups. This is the scene where we often see ants moving in line.
