Water liquid changing to water vapor. (liquid-gas)
Change from a water vapor to a liquid. (gas-liquid)
Water vapor to ice without the liquid stage.
ice to water vapor without the liquid stage.
measure of how close the air is of being saturated.
formed by condensation that occurs by radiational cooling at the surface.
formed by deposition when the dew point below freezing.
formed in Hygroscopic condensation nuclei/visibility more than a half a mile.
Hygroscopic condensation nuclei
have a special chemical attraction for water molecules so that water vapor collects on them even when the air is not completely saturated.
the altitude at which the relative humidity reaches 100%
The temperature at which the relative humidity reaches 100%.
occurs at 130 degrees or higher.
afternoon, high, A type of cumulus cloud that is tall and gray that is associated with thunderstorms.
high, thin clouds that give the sky a milky-white appearance and sometimes make a halo around the sun or moon
small, rounded white puffs in long rows, resemble the scales of a fish, usually seen in winter
associated with vertically developed clouds/does not last long
len shape/formed over mountains/UFO
low clouds that occur in a uniform gray layer.
Resembles white fluffy cotton balls or heaps
Indicates upward vertical motion or thermal uplift of air
Tops can reach 60,000 feet
May produce icing, turbulence, and other hazards
Circle of light around the sun or moon.
gray to blue gray usually covering the entire sky. Sun may appear as a dull rounded disk with no shadows cast. Usually form in advance of storms that produce much widespread and continuous precipitation.
clouds that are low-level, uniform layer, usually very dark, that bring strong precipitation (rain).
looks like a , also known as mammatocumulus, meaning "Mammary cloud" or "Breast cloud" is a meteorological term applied to a cellular pattern of pouches hanging underneath the base of a cloud
high, thin, white, feathery clouds made of ice crystals. Resemble's mares tails.
Below/very small clouds, cumulus clouds that show only slight vertical growth and are associated with fair weather
vertical developnent, avil top, very large, lot of stuff going on , storm at the bottom, low levels that go up
middle clouds made of water droplets or ice crystals; appear as gray puffy masses; usually form in groups;usually occur thunderstorms
liquid in the air, the amount of water vapor in the air.
the pressure caused by the collisions of particles in a vapor with the walls of a container
dew point below freezing.
clouds on the ground
If the amount of water vapor in the air remains the same, but the temperature decreases, the relative humidity___________.
What time of the day is dew more likely to occur?
Dew is more likely to form when the sky is______.
If the amount of water vapor remains constant, the relative humidity is usually highest around ___________.
Radiational cooling occurs best when nights are _______ and skies are ________.
Relative humidity can be high, with very little water vapor in the air, when the air is _______.
Evaporation increases when the air is ____________.
HOT & DRY
Liquid water drops larger than 0.5 mm that fall to the earth.
Liquid water drops smaller than 0.5 mm that fall to the earth.
Liquid water drops that fall to the earth and freeze when they come into contact with objects below freezing at the earth's surface.
Formed when the rain drop freezes as it falls, before reaching the surface.
Jagged lumps of ice formed in layers as they move up and down in a cloud because of strong winds.
Causes damage to power lines and limbs.
process that takes place without a transfer of heat between an air parcel and the surrounding air.
is a small amount of air that is considered as a single unit explaining the behavior air.
solid particles in the air which serve as centers for water vapor to collect on during cloud formation.
the release of water from the leaves of plants.
occurs at night as the earth's surface and the air above it give of infrared energy and lose more energy than they receive.
the merging of small cloud droplets into a single larger droplet.
the process by which a solid changes
air that is surrounding an air parcel on all sides.
