Temperature increases with height in the troposphere and decreases with
height in the stratosphere. - ANSWER false
Except very near the Earth's surface, the force of friction acts primarily
through the mixing of air moving at different speeds. - ANSWER True
What term is used to describe the net-inward directed force found in
symmetrically curved flow in the upper atmosphere? - ANSWER centripetal
acceleration
All air on the Earth has angular momentum. - ANSWER False
Which term is defined by the rate at which pressure changes with distance -
ANSWER pressure gradient
Jet streams are located at one latitude in the upper atmosphere and do not
influence storm systems at the surface. - ANSWER false
How does the average speed of air molecules influence the atmosphere? -
ANSWER It determines the air temperature.
What type of surface pressure systems are typically associated with fair
weather? - ANSWER high pressure
Which statement about air motions is not correct? - ANSWER Low- Pressure
centers are associated with strong convergence aloft.
In the Northern Hemisphere, the force of friction, along with the pressure
, gradient and Coriolis forces, causes surface winds to blow: - ANSWER
counterclockwise and in towards the center of surface low-pressure systems.
What is the term used to describe the net inflow of air molecules into a
region of the atmosphere with the result of increasing the surface pressure? -
ANSWER convergence
Friction - ANSWER decreases surface wind speeds, ultimately leading to air
flowing toward surface low-pressure centers.
Pressure varies in the vertical from 1013.25 mb at Earth's surface (on
average) to what value near the tropopause? - ANSWER ~300 mb
What is the weight of the air above a unit area? - ANSWER Pressure
In clear skies at cruise altitudes, what type of turbulence most likely results in
commercial aircrafts flights becoming "bumpy" and the pilot illuminating the
"fasten seat belt" sign? - ANSWER shear-induced turbulence
What is the term used to describe a narrow band of strong winds encircling
the Earth in middle-latitudes? - ANSWER Jetstream
The Coriolis force is an apparent force due to the rotation of the Earth. -
ANSWER True
Convergence into an air column ________ mass to the column resulting in
________ surface pressure. - ANSWER adds; increased
The _________ is an apparent force associated with the rotation of the earth. -
ANSWER Coriolis force
What is the term used to describe a region of exceptionally strong winds
found within the jetstream? - ANSWER jetstreak
