 Jet streams are fast winds that blow high above the Earth. They move like rivers of wind and travel at very high speeds. These winds can go as fast as 320 km/h!
Jet streams affect the weather. They push clouds and storms around the world. There are different jet streams, and they move in different directions.
Jet streams are very important because they decide what the weather will be like in different places. In winter, jet streams can bring cold weather. In summer, they bring warm air.
Planes use jet streams to help them fly faster and save fuel. They are like invisible highways in the sky!
