Solution

The correct option is A Jetstreams
The first flowing cold air current in the upper atmosphere is called Jetstream. The term jet stream was first applied to the high-velocity upper-level winds during World War II. The jet stream is a relatively narrow band of strong winds bounded by slower moving air. Jet streams are characterized by a great seasonal variation.
