gas to solid without ever being a liquid |
|
|
vapor pressure |
part of the atmospheric pressure attributes to water vapor |
|
|
saturation |
max. quantity of water vapor that the air can hold |
|
|
relative humidity |
ratio of the air's water vapor content to its max capacity |
|
|
dew point |
temperature to which a particular parcel of air has to be cooled to reach saturation |
|
|
adiabatic temperature changes |
cooling or warming of air caused when air is allowed ti expand or is compressed |
|
|
wet adiabatic rate |
rate of adiabatic cooling or warming in saturated air (5-9 C/ 1 km altitude) |
|
|
dry adiabatic rate |
rate of adiabatic cooing or warming in unsaturated air (1 C/ 1km) |
|
|
orographic lifting |
air is forced to rise over the mountains |
|
|
frontal wedging |
warmer, less dense air is forced to rise over cooler, more sense air |
|
|
convergence |
pileup of horizontal airflow forces air upward |
|
|
localized convective lifting |
unequal heating of ground warms air, making it less dense, an forces it to rise bc of its increased buoyancy |
|
|
rain shadow dessert |
dry area on the lee side of a mountain range |
|
|
front |
boundary between 2 air masses having different characteristics |
|
|
stable air |
air that resists vertical displacement |
|
|
unstable air |
air that does not resist veinal displacement |
|
|
absolute stability |
air with a lapse rate less than the wet adiabatic rate |
|
|
conditional stability |
moist air with a lapse rate between the dry and wet adiabatic rate |
|
|
clouds |
dense concentration of suspended droplets and ice crystals |
|
|
stratus |
sheet or layer like clouds |
|
|
cumulus |
cloud masses that often have flat bases |
|
|
aerosols |
solid and liquid particles suspended in the atmosphere |
|
|
condensation nuclei |
tiny bits of particulate matter that serves as surfaces on which water vapor condenses |
|
|
collision- coalescence process |
large cloud droplets collide and join together to for a raindrop |
|
|
Bergeron Process |
supercooled water freezes on contact with freezing nuclei to from ice crystals on which water vapor deposits to from snow crystals |

|
rain |
drops of water that fall from clouds, at least at a diameter of .5 mm |
|
|
snow |
solid form of precipitation |
|
|
sleet |
frozen or semi frozen rani formed when raindrops freeze as they pass through a layer of cold air |
|
|
glaze |
a coating of ice on objects formed when supercooled rain freezes on contact |
|
|
hail |
nearly spherical ice pellets having concentric layers formed by the successive freezing of layers of water |
|
|
rime |
thin coating of ice on objects produced when supercooled fog droplets freeze on contact |
