Jet Stream Flashcards
During the winter months in the middle latitudes, the jet stream shifts toward the
south and speed increases.
The strength and location of the jet stream is normally
weaker and farther north in the summer.
A common location of clear air turbulence is
in an upper trough on the polar side of a jet stream.
The jet stream and associated clear air turbulence can sometimes be visually identified in flight by
long streaks of cirrus clouds.
A strong wind shear can be expected
on the low-pressure side of a Jetstream core where the speed at the core is stronger than
110 knots.
Which type of Jetstream can be expected to cause the greater turbulence?
A curving Jetstream associated with a deep low-pressure trough.
Which feature is associated with the tropopause?
Abrupt change in temperature lapse rate.
