B
People started to study the weather very early. They used many different ways. Some are still useful. Let's have a look!
Watch the sky
Look at the clouds. Different kinds mean different weather. How the clouds move also means different weather. Usually, white and high clouds mean good weather. Dark and low clouds mean bad weather.
Look at the red sky. Your parents may tell you, "Red sky in the morning: don't go out. Red sky at night: it's safe to go out." Well, this is quite right!
Watch the animals
Look at the birds. Usually, they fly very high in the sky. And this means good weather. Sometimes, they fly very low in the sky. And this means bad weather. The birds are also very quiet before it rains.
Look at the turtles(乌龟). Before bad weather comes, they'll climb very slowly to a high place. You can see them on the road one to two days before it rains.
Look at the cows. Sometimes, they stay together and keep quiet, because bad weather is on the way.
Look at the fish. If they jump out of the water, it's a sign(标志) that the stormy weather may be coming.
