Earth And Space Science Gt Chapter 24 Water In The Atmosphere

Front 1

Adiabatic

Back 1

describing a change in temperature resulting from the expansion or compression of air.

Front 2

Advection fog

Back 2

condensation of water vapor that results from the cooling of warm, moist air as it moves across a cold surface.

Front 3

Advective cooling

Back 3

decrease in the temperature of a mass of air that results as it moves over a cool surface.

Front 4

Cirrus Cloud

Back 4

feathery cloud composed of ice crystals that has the highest altitude of any cloud in the sky.

Front 5

Cloud seeding

Back 5

addition of freezing nuclei to supercooled clouds in an attempt to induce or increase precipitation.

Front 6

Coalescence

Back 6

combination of different sized cloud droplets to form larger droplets.

Front 7

Condensation nuclei

Back 7

solid particles in the atmosphere, such as ice and dust, that provide the surfaces on which water vapor condenses.

Front 8

Convective Cooling

Back 8

decrease in temperature of a mass of air that results as the air rises and expands

Front 9

Cumulus Cloud

Back 9

thick, billowy clud that forms above stratus clouds and below cirrus clouds.

Front 10

Dew

Back 10

type of consation formed when air that is in contact with a cool surface loses heat until it reaches saturation.

Front 11

Dew Point

Back 11

temperature to which air must be cooled to be saturated.

Front 12

Freezing nuclei

Back 12

condensation nuclei with a crystalline structure like that of ice.

Front 13

Frost

Back 13

ice crystals formed when the dew point is below 0°C and water vapor directly enters the solid state.

Front 14

Glaze Ice

Back 14

thick layer of sheet ice formed when rain freezes as it contacts a surface.

Front 15

Hail

Back 15

type of precipitation in the form of lumps of ice.

Front 16

Hair hygrometer

Back 16

instrument used to measure relative humidity, based on the fact that human hair stretches as humidity increases.

Front 17

Humidity

Back 17

amount of water vapor in the atmosphere.

Front 18

Latent heat

Back 18

energy stored in molecules.

Front 19

Psychrometer

Back 19

instrument used to measure relative humidity.

Front 20

Radiation fog

Back 20

condensation of water vapor that results from the cooling of air that is in contact with the ground.

Front 21

Rain gauge

Back 21

instrument used to measure the amount of rainfall.

Front 22

Relative Humidity

Back 22

ratio of the amount of water vapor to the amount of water vapor the air can hold when saturated.

Front 23

Saturated

Back 23

describing air that contains all that of the water vapor that it can hold at a specific temperature.

Front 24

Sleet

Back 24

ice pellets that form when rain falls through a layer of freezing air.

Front 25

Specific Humidity

Back 25

actual amount of moisture in the air.

Front 26

Steam Fog

Back 26

condensation of water vapor that results when cool air moves over warm water.

Front 27

Stratus Cloud

Back 27

cloud with a sheetlike or layered from that is the lowest cloud in the sky.

Front 28

Sublimation

Back 28

process in which a solid turns directly into a vapor.

Front 29

Supercooling

Back 29

process in which water droplets are induced to remain liquid at temperatures below 0°C.

Front 30

Upslope Fog

Back 30

condensation of water vapor that results form the lifting and adiabatic cooling air rising up a slope of land.
