1)
Which
of the following does not contribute to the summer monsoon in India?
a)
Onshore
breezes
b)
An
upper level jet
c)
Convergence
of air
d)
A
persistent high pressure system
2)
Moving
air is subjected to a pressure gradient force, a Coriolis force, and a
frictional force. Which of these forces
has little or no influence on moving water in the ocean?
a.
Pressure
gradient force
b.
Coriolis
force
c.
Frictional
force
3)
Which
direction do winds tend to blow on either side of a stationary front?
a.
Perpendicular
to, and away from, the front.
b.
Perpendicular
to, and towards, the front.
c.
Parallel
to the front, and in opposite directions.
d.
Parallel
to the front, and in the same direction.
4)
Why
are middle latitude cyclones more frequent in the southern U.S. during winter
than they are during the summer?
a.
Because
the polar front moves farther south in the winter.
b.
Because
onshore breezes in the summer push the storms towards the north.
c.
Because
only cT air masses are found over the Southern U.S. in the summer.
d.
Because
there are prevailing easterlies in the Southern U.S. during the summer, but
prevailing westerlies during the winter.
5)
Why
is absolute vorticity almost always positive over the U.S. even though rotation
of the atmosphere is sometimes clockwise and sometimes counterclockwise?
a.
Because
the Earth’s vorticity is positive and large.
b.
Because
jet streams usually move from west to east.
c.
Because
air is usually only rotating clockwise near the equator where the Earth’s
vorticity is less.
d.
Because
the mountain ranges in the U.S. disrupt any clockwise rotation.
6)
How
can one thunderstorm (or thunderstorm cell) initiate other thunderstorms (or
cells)?
a.
By
saturating the upper atmosphere.
b.
The
thunderstorm’s downdraft can force adjacent warm, moist air up.
c.
By
causing a kink in the jet stream.
d.
By
causing a temperature inversion.
7)
About
1000 tornadoes occur in the U.S. every year.
About how many of those are F5 tornadoes?
a.
100
b.
10
c.
1
d.
An
F5 has never occurred in the U.S.
