How do ants predict weather changes?

Ants came out of the hole in droves, which indicated that heavy rain was coming. As the saying goes, "ants are in droves, and tomorrow will not be sunny."

Ants move, it's raining!

Before the rain, due to the increase of humidity in the air, the water absorbed by the soil increased greatly. Therefore, the nests of ants living in the soil become wet. Although ants live underground, they naturally like to be dry. It has an organ that can sense water on the body. Before the rainstorm, when the moisture in the air is too high, it feels like rain. Ants will crawl out and move to higher places to avoid being flooded by rain.

Ants predict the weather by moving. Once it rains, they move one place at a time. If they move lower, it means less rainfall. If you go higher, it means more rain. When ants block the entrance to the nest, it indicates that there will be heavy rain. This is because ants are very sensitive to changes in air pressure and humidity. Once they feel that it is going to rain heavily, they will block the nest mouth to prevent rainwater from infiltrating and ensure life safety. Sometimes they move from east to west, sometimes from west to east, which tells us that it will rain wherever it moves! However, if it only rains in Mao Mao, it is difficult for ants to observe it.
