They're called 'jet streams'.

Jet Streams.
High altitude high velocity winds are known as jet streams. These narrow bands of strong winds flow in the upper atmosphere, typically between 7 and 12 kilometers above the Earth's surface. Jet streams can influence the weather patterns and air travel routes.
A river of ice is a glacier.
High altitude vegetation is typically called "alpine", from the plants that grow high up in the Alps mountain range.
Because of the high altitude, these winds are not subject to much friction, hence they are faster than winds closer to earth's surface.
