How do jet streamsinfluence the weather?

Jet streams act as an invisible director of the atmosphere and are largely responsible for changes in the weather across the globe. A jet stream is essentially an atmospheric highway located at the level where jets cruise. Winds in this high-speed river of air often reach 250 mph.

Jet streams have slim strips of strong winds that have a huge influence on climate, as they can push air masses around and affect weather patterns.
