through 14-8.
5-1.
Of the following statements, which
one is valid regarding the
development of tropical systems?
1.
Trade inversions may accelerate
development
2.
Warmer, drier air may
accelerate development
3.
Twice as many tropical systems
develop over the Atlantic Ocean
as the Pacific Ocean
4.
Cooler, drier air tends to
hamper development
5-2.
Which of the following weather
patterns would be indicative of
tropical cyclone development?
1.
Easterlies increasing with
height
2.
Cyclonic turning in the wind
field
3.
Outflow at the lower levels
4.
Decreasing surface pressure
gradient to the north of the
suspect area
5-3.
Long period swell waves may be an
indication of the development of a
tropical system.
1.
True
2.
False
5-4.
All EXCEPT which of the following
weather patterns would be an
indication of the deepening of a
tropical system?
1.
Movement over warmer water
2.
The presence of a trade
inversion
3.
Poleward migration of the
system
4.
Deceleration of the system
5-5.
Tropical cyclones that form along
the eastern periphery of a polar
trough tend to move in what
direction?.
1.
Toward the southeast
2.
Toward the west
3.
90° to the left of the
orientation of the trough line
4.
Along the trough
5-6.
Upper-level winds may be used for
the steering of tropical systems.
Which of the following wind
patterns should be given the most
consideration?
1.
Those to the rear of the system
2.
Those in advance of the system
3.
Those in the left semicircle of
the system
4.
Those in the right semicircle
of the system
5-7.
Which of the following synoptic
features would be an indicator of
tropical cyclone recurvature?
1.
2.
3.
4.
The base of the polar
westerlies lowers to 15,000 to
20,000 feet east of the storm’s
latitude
There are no breaks in the
subtropical high
Long waves are stationary or
slowly progressive
The neutral point in the
southern extremity of the
trough in the westerlies at the
500-hPa level lies poleward of
the storm’s latitude
5-8.
Assume that the associated long
wave is progressive, and the
surface high slopes to the
southeast with height.
Which of
the following weather patterns
would be indicated relative to a
tropical cyclone?
1.
The tropical cyclone comes
under the influence of the
upper westerlies, and its track
would reverse itself
2.
The tropical cyclone comes
under the influence of the
upper easterlies, and its track
would reverse itself
3.
The tropical cyclone comes
under the influence of the
upper easterlies, and a large
degree of recurvature would
take place
4.
The tropical cyclone comes
under the influence of the
upper westerlies, and a small
degree of recurvature would
take place
