The weather forecast is always inaccurate. How do you know if it will rain?

Observe the sky: in the afternoon, see if there is a sunset glow in the sky. If there were, it wouldn't rain tomorrow. Observe whether there is a sunrise in the sky. If so, it will rain this afternoon or tomorrow. Then, before it rains, the air humidity is high, and dark clouds are pressing overhead, which indicates that it will rain heavily soon.

Observe animals: see if the ants are moving, if so, it will rain recently; Look at the swallow flying low. Before it rains, insects will come out early and fly at low altitude, so swallows will fly low and eat insects. Earthworms come out of the hole, which indicates that it will rain heavily. Earthworms come out early to prevent drowning. Chickens and ducks don't want to go into the nest, which also means that it will rain heavily and the air is airtight, so the nest will be very stuffy, which is a precursor to heavy rain. Observe the small fish by the river. If they all pay the water surface, it means that the air pressure at the bottom of the water is low and the small fish are breathing on the water surface. Low air pressure is also a signal before rain. Observe the dog at home. If dogs love to bathe by the river, it means that the air is sultry and it will rain in recent days. Zen stopped screaming, the weather was fine, and suddenly it was cloudy. Zen didn't want to scream, indicating that it was going to rain. Observe toads. Toads usually hide in wet grass. When the air is humid and the air pressure is low, the toad will come out of the grass with a very loud voice.
