The cloud form that is best described as sheets or layers that cover much or all of the sky is termed |
stratus |
|
The cloud form that consists of globular cloud masses that take o a billowy or "cauliflower-like" structure is called |
cumulus |
|
This term is used to describe clouds founding the middle height range |
alto |
|
High clouds that form delicate veil-like patches o extended wispy fibers are termed |
cirrus |
|
This term is used to describe clouds that produce precipitation |
nimbo |
|
These clouds are often called "fair weather" clouds |
cumulus |

cirrus |
|
Thunder and lightning are associated with these clouds |
cumulonimbus |
|
This cloud type is confined to the middle height range |
altostratus |
|
A halo around the Sun or Moon indicates that this cloud type is present |
cirrostratus |
|
A dark gray cloud that blankets the sky and often generates precipitation is called |

cumulonimbus |
|
Tornadoes can be associated with this cloud type |
cumulonimbus |
|
Hail is most commonly associated with |
cumulonimbus |
|
A wintertime form of precipitation that consists of small ice particles is called |
sleet |
|
This fog forms in valleys at night |
radiation fog |
|
When warm moist air moves over a cool surface, _______ fog may result. |
advection |
|
This fog results from adiabatic cooling. |
upslope |
|
Which one of the fogs listed below may be categorized as an evaporation fog? |
seam |
|
When super cooled raindrops freeze on contact with solid objects, ____ forms. |
glaze |
|
The amount of water vapor in the air (by volume) usually does not exceed |
4% |
|
We are likely to have our highest relative humidity |
about sunrise |
|
When using a psychrometer and the two temperatures read nearly the same, you can conclude that ________. |
the air has a high relative humidity |
|
Under what circumstances could the relative humidity exceed 100% without producing condensation in the air? |
there are no condensation nuclei |
|
The dew point is the temperature at which |
water vapor condenses to a liquid |
|
The most important process of cloud formation in the atmosphere is |
cooling by expansion of air |
|
If air at sea level with a temperature of 27 C is forced up a mountain slope and the air’s dew point at the condensation level is 14 degree C, at what elevation will condensation begin? |
1300 meters |
|
Stability prevails when the environmental lapse rate is |
less than the wet adiabatic rate |
|
When air is unstable, the environmental laps rate is |
greater than the dry adiabatic rate |
|
Which of the following will NOT cause air to become more unstable? |
subsidence of an air column |
|
Which of the following would NOT be associated with stable atmospheric conditions? |
afternoon thunder showers |
|
A parcel of air has a temperature of 0 degrees Celsius as it crosses a mountain range at 3000 metes. If it descends, what will its temperature be when it reaches sea level? |
30 degree celsius |
|
Deserts such as the Great Basin, Gobi, and Takla Makan are examples of |
rainshadow deserts |
|
The change of state from a gas to a liquid is called |
condensation |
|
The term ______ is used to describe the conversion of a solid directly to gas, without passing through the liquid state. |
sublimation |
|
The process by which water vapor changes directly to a solid is called |
deposiion |
|
This process results in the release of about 600 calories of latent heat per gram of water. |
condensation |
|
The process of converting a liquid to vapor is termed |
evaporation |
