You are looking downstream and find
that high-speed winds are moving
towards weak, cyclonically curved
contours.
What effect should this
have on upper-level heights?
1.
Heights should decrease
downstream to the left
2.
Heights should decrease
downstream to the right
3.
Heights should increase
downstream to the left
4.
Heights should increase
downstream to the right
1-10.
When an anticyclonic circulation
center is out of phase with its
pressure center, what movement(s)
bring(s) about a readjustment?
1.
The movement of the circulation
and pressure centers toward
each other
2.
The movement of the circulation
center toward the pressure
center
3.
Both 1 and 2 above
4.
The movement of the pressure
center toward the circulation
center
1-11.
You encounter a well-developed
ridge that has sharply curved
anticyclonic contours with a deep
trough a short distance downstream.
What action should you expect to
take place?
1.
Deepening and reorientation of
a portion of the trough
2.
The cutoff low to retrograde
from its position and the
trough to reorient
3.
Dissipation of the low at the
lower end of the trough,
depending on the initial winds
in the ridge to the west
4.
Filling and reorientation of
the trough
1-12.
Under what condition does the
greatest overshooting of high-speed
winds occur?
1.
When high-speed winds in the
ridge are more than twice the
measured geostrophic winds
2.
When measured geostrophic winds
in the ridge are more than
twice the high-speed winds in
the ridge
3.
When low-speed winds approach
the west side of the
anticyclonic ridge
4.
When low-speed winds are
located in the southwesterly
flow of the downstream ridge
1-13.
Convergence on the western side of
a downstream trough has what
results?
1.
Dynamic heating
2.
A decrease in upper-level
heights
3.
An increase in upper-level
heights
4.
A decrease in moisture
1-14.
Which of the following statements
concerning the convection process
is valid?

4.
Stratiform type clouds
predominate in areas of
convection
1-15.
Upward motion will always result in
cloudiness.
1.
True
2.
False
1-16.

atmospheric rotation
4.
