Question 6
the reason there is a difference between the âmoistâ and âdryâ adiabatic rates is because
latent heat is released by a rising parcel air.
an unsaturated air parcel expands more rapidly than a saturated air parcel.
moist air weighs less than dry air.
dry air weighs more than moist air
question 7
the ratio of the actual amount of water vapor in the atmosphere to the maximum possible at that temperature is the
absolute humidity
specific humidity
relative humidity
dew point temperature
flag this question
question 8
the processes most responsible for water vapor entering the atmosphere:
evaporation and transpiration
sublimation and deposition
short wave radiation and long wave radiation
conduction and convection
question 9
the wet (moist) adiabatic rate is around
10.0â°celsius/1000 meters
4.0-9.0â°celsius/1000 meters
0.5â°celsius/meter
5.0â°celsius/100 meters
question 10
at the dew point temperature
the maximum amount of latent heat is absorbed
frost and dew occur simultaneously
the air is both saturated and has a 100% relative humidity.
specific humidity peaks
question 11
pressure gradients try to drive winds:
parallel to isobars
perpendicular to isobars
from low to high pressure
none of the above
question 12
in the convection loop known as a sea breeze:
warm air expands and rises over the water during daytime
air descends over the land, creating higher pressure at the surface during daytime
the pressure gradient drives a flow from sea to land aloft during daytime
the pressure gradient drives a flow from sea to land at the surface during daytime
question 13
the coriolis effect results from:
pressure gradients
differences in heating
friction
the earth's rotation
question 14
in a northern hemisphere anticyclone, the wind flow is:
clockwise inward
counterclockwise inward
clockwise outward
counterclockwise outward
question 15
ocean currents can be driven by:
differences in water heating
differences in salinity
wind
all of the above
question 16
the atmosphere exerts pressure because:
air molecules are attracted to each other
gravity pulls air molecules towards earth
air molecules expand with elevation
all of the above
question 17
narrow bands of high-speed air flowing in the upper troposphere are known as:
geostrophic winds
rossby winds
polar easterlies
jet streams
question 18
a maritime tropical air mass would be expected to be:
warm and dry
warm and moist
cool and dry
cool and moist
question 19
a cp air mass would be expected to be:
warm and dry
warm and moist
cool and dry
cool and moist
question 20
which of the following is not a cyclonic storm?
tornado
hurricane
wave cyclone
monsoon
question 21
a traveling cyclone of the mid-latitudes that involves interaction between cold and warm air masses along sharply defined fronts is a:
tornado
hurricane
wave cyclone
monsoon
