WX 201 TEST 2 ERAU UPDATED ACTUAL QUESTIONS AND
CORRECT ANSWERS
Question:
1. station pressure
Answer:
the actual air pressure computed at the observing station
Question:
2. sea level pressure
Answer:
the standard level of pressure 29.92 inches
Question:
3. ideal gas law
Answer:
the relationship PV=nRT, which describes the behavior of an ideal gas
Question:
4. mercury barometer
Answer:
consists of a glass tube open at the bottom end and partially filled with mercury
Question:
5. barometric pressure
Answer:
the pressure due to the weight of the atmosphere; also called air pressure or atmospheric pressure
Question:
6. aneroid barometer
Answer:
An instrument that measures changes in air pressure without using a liquid.
-Measured in millibars
Question:
7. barograph
Answer:
An instrument that registers graphically and continuously the atmospheric pressure.
Question:
8. pressure gradient force
Answer:
the amount of pressure change occurring over a given distance
, Question:
9. hydrostatic equation
Answer:
pressure drops more rapidly with increasing height at high latitudes and lowers the height of 500 mb level.
Question:
10. Coriolis force
Answer:
The apparent force, resulting from the rotation of the Earth, that deflects air or water movement.
Question:
11. friction
Answer:
A force that opposes motion between two surfaces that are in contact
Question:
12. planetary boundary layer
Answer:
is the lowest part of the atmosphere. Its behavior is directly influenced by its contact with a planetary
surface
Question:
13. geostrophic flow
Answer:
A current in the atmosphere in which the Coriolis force and the pressure gradient are in balance.
Question:
14. gradient flow
Answer:
associated to a functional on a manifold which has a geometric interpretation, usually associated with some
extrinsic or intrinsic curvature.
Question:
15. anticyclone
Answer:
A high-pressure center of dry air
Question:
16. cyclones
Answer:
winds around centers of low atmospheric pressure bad storm
Question:
17. troughs
Answer:
low points on a wave
