When you are considering the
curvature effect alone for an
evaluation of relative vorticity,
point P is considered to be a point
of NO curvature and, therefore,
zero vorticity.
What is another
name for this point of NO
curvature?
1.
Mid-point of vorticity
2.
Point of negative vorticity
3.
Point of positive vorticity
4.
Inflection point

If only the curvature effect were
considered,
the relative vorticity
would increase in which of the
following regions?
1-20.
When relative vorticity is
decreasing downstream in the upper
troposphere,
what should you expect
to occur?
1.
Convergence aloft and surface
pressure falls
2.
Decreased precipitation if
sufficient moisture was
initially present
3.
Decreased thicknesses between
standard isobaric surfaces in
the region of decreasing
relative vorticity
4.
Divergence aloft and surface
pressure falls
1-21.
Long waves of relatively short
wavelength,
well-defined major
troughs and ridges, and well-
developed surface cyclones and
anticyclones are associated with
which of the following wave
patterns?
1.
Changing long-wave patterns
2.
Retrogression of long waves
3.
Progressive long waves
4.
Stationary long waves
1-22.
Which of the following conditions
would NOT be an indication of the
retrogression of a long wave?
1.
Increased cold air advection in
the upstream ridge
2.
24-hr height change
trajectories do not correspond
to the band of maximum winds
3.
New height centers appear
4.
Surface lows to the west of the
major trough position deepen
