What weather forecasters are there in nature?

1. Fish in the water can predict rainfall. Because the air humidity is very heavy before rain, there will be a lack of oxygen in the air. Therefore, gill-breathing fish will not appear on the water surface. !

2. Dragonfly, if the dragonfly flies too low, it means it will rain heavily soon. The reason is the same as the above example!

3. The moon at night, if there is a circle around the moon A large round halo indicates that the next day will be very hot. This is also the so-called "moon wearing a straw hat"
