Jet Streak - A local wind speed maximum within a jet stream.
Jet Stream - Relatively strong winds concentrated in a narrow
stream in the atmosphere, normally referring to horizontal,
high-altitude winds. The position and orientation of jet streams
vary from day to day. General weather patterns (hot/cold, wet/dry)
are related closely to the position, strength and orientation of the
jet stream (or jet streams). A jet stream at low levels is known as
a low-level jet.
