As the air temperature increases, the air's capacity for water vapor


Which of the following will increase in a rising parcel of air?

relative humidity

High water vapor pressure indicates

A relatively large number of water vapor molecules in the air

The percentage of water vapor present in the air compared to that required for saturation

relative humidity

At what time of day is the relative humidity normally at a minimum?

When the air temperature is highest

The dew point temperature is a measure of the total amount of water vapor in the air. T/F


If the air temperature remains constant, evaporating water into the air will __ the dew point and __ the relative humidity

increase, increase

As the difference btwn air temp. and dew point increases, the relative humitidy


The temp to which air must be cooled in order to become saturated is the

dew point temperature

As the air temp increases, w/ no addition of water vapor to the air, the dew point will:

remain the same

Dew is most likely to form on

clear, calm nights

The cooling of the ground to produce dew is mainly the result of

radiational cooling

Particles that serve as surfaces on which water vapor may condense are called

Condensation nuclei

On a humid day, the ___ causes salty potato chips left outside in an uncovered bowl to turn soggy

attraction of water by hdygroscopic condensation nuclei

Condensation nuclei may be

Particles of dust
Nitric acid particles
Smoke from forest fires
Salt from the ocean

Condensation nuclei are important in the atmosphere because

they make it easier for condensation to occur in the atmosphere

When radiation fog "burns off", the fog tends to dissipate

From the bottom up

Radiation forms best on a

clear night with a slight breeze

On a cold, winter morning the most likely place for radiation fog to form is

in a valley

The fog that forms along the Pacific coastline of North America is mainly this type

Advection fog

If fog is forming in Denver, CO, and the wind is blowing from the east, the the fog is most likely

Upslope fog

When you see your breath on a cold morning the air temperature

Can be above or below freezing

For is a major hazard to aviation T/F


Which association is not correct?

altostratus=high cloud

Which associatoin is not correct?

Cumulus congestus=anvil top

Which cloud is least likely to produce precipitation that reaches the ground?


A halo around the moon means that

Cirrostratus clouds are present

Which cloud type is composed of ice crystals and can form a halo around the moon or sun?


Which of the following associations is not correct?

Stratocumulus -- cloud of vertical development

Light or moderate-but-steady precipitation if most often associated with


Which of the following cloud types are very similar in appearance?

Altocumulus and cirrocumulus

Cirrus clouds are composed primarily of

ice particles

A middle cloud that sometimes forms in parallel waves or bands is


An anvil-shaped top is most often associated with


Name given to towering cloud that has not fully developed into a thunderstorm

cumulus congestus

A low, lumpy cloud layer that appears in rows, patches or rounded masses would be


Hail is usually from what cloud?


The cloud with the greatest vertical growth is


The small smooth cloud that may form just above the top of a towering cumulus cloud is a

pileus cloud

The cloud-like streamer often seen forming behind an aircraft flying at high altitude is a


Clouds that have a characteristic lens-shaped appearance are referred to as


Clouds that appear as bag like-sacks hanging beneath a cloud are


On an infrared satellite picture, low warm cloud appear ___ and high cold clouds appear ___

gray, white

Geostationary satellites

Orbit the earth once a day
Remain above a fixed spot on the equator
Are placed in higher orbits than most polar orbiting satellites

On humid days, salt in saltshakers sometimes becomes moist and no longer pours out easily. The salt can be described as


Radiation fog typically forms on

clear, calm nights
