SOLUTION
A strong high-pressure system might have a central sea level pressure of
1045 mb, while a deep low pressure system might have a central sea level
pressure of 980 mb. T or F - ANSWER True
Which statement(s) is(are) false?
a. Latent heat can be directly measured with a thermometer.
b. Latent heat release is vital to the creation of thunderstorms.
c. Latent heat can be observed visually in a developing thunderstorm.
d. Latent heat is the energy required for a phase change (e.g., vapor to
water).
e. a and c are both false - ANSWER e
What unit of pressure is most commonly used by meteorologists? - ANSWER
mb
What is the average value of sea level pressure? - ANSWER 1013.25 mb
Deep storms can occur in the tropics where the tropopause is at a high
altitude. Storms in the polar regions are more shallow because the
tropopause is not as high over the poles. T or F - ANSWER True
If the temperature on the Fahrenheit scale is 100 degrees, then the
corresponding temperature on the Celsius scale is greater than 100 degrees.
T or F - ANSWER False
,What term describes the pressure at which the air contains the maximum
amount of water vapor possible for the observed temperature and pressure?
- ANSWER saturation vapor Pressure
A device used by meteorologists to measure atmospheric pressure is called a
squashometer. T or F - ANSWER False
Pressure varies in the vertical from 1013.25 mb at Earth's surface (on
average) to what value near the tropopause? - ANSWER 300 mb
Air through a trough flows _____________. - ANSWER cyclonically
Which term is defined by the rate at which pressure changes with distance? -
ANSWER Pressure Gradient
The Coriolis force increases as the wind speed increases, except directly on
the equator where the Coriolis force is zero. T or F - ANSWER True
What is the term used to describe a narrow band of strong winds encircling
the Earth in middle-latitudes? - ANSWER Jet stream
When the Coriolis force balances the _________ the air is in geostrophic
balance. - ANSWER horizontal pressure gradient force
Which of the following is not a force that controls the wind? - ANSWER
electrostatic force
If only atmospheric _______ were occurring in an air column, the pressure at
the base of the air column would always _______. - ANSWER divergence;
decrease
What type of surface pressure systems are typically associated with fair
weather? - ANSWER high pressure
, Near the surface, air spirals out of low-pressure centers. T or F - ANSWER
False
Which statement is not correct?
a. Friction always reduces the wind speed.
b. Friction leads to the strengthening of surface low-pressure centers.
c. Friction leads to a deflection to the left of the geostrophic wind direction,
toward the low pressure side of isobars.
d. Friction always acts to turn the wind such that the flow has a component
from higher pressure toward lower pressure.
e. Friction influences air flow up to roughly 3 km above the surface. -
ANSWER b
Which of the following can enhance surface low-pressure systems? -
ANSWER divergence in the left exit
The boundary between two different airmasses is called a front. T or F -
ANSWER True
It is May on the Great Plains. A cold front is advancing toward you. What
type of weather conditions would you expect to find if the cold front is
advancing into warm, moist, stable air? - ANSWER widespread fog
It is May on the Great Plains. A cold front is advancing toward you. What
type of weather conditions would you expect to find if the cold front is
advancing into warm, moist, conditionally unstable air? - ANSWER
Thunderstorms
Flooding can be a significant hazard associated with stationary fronts. -
