Atmosphere moisture Flashcards
What is the level of the bottom of the cloud?
Liquid condensation level
What is the hydrologic cycle?
Circulation of the Earth’s water supply between atmosphere and surface
What are phase changes?
Evaporation, freezing, condensation, deposition, sublimation
What is the temperature of the cloud?
Dew point temperature
What is happening to the air?
Became saturated (was unsaturated)
What is evaporation?
Liquid water to water vapor
What is freezing?
Liquid water to ice
What is condensation?
Water vapor to liquid water
What is melting?
Ice to liquid
Each phase involves what?
Involves an exchange of latent heat
What is latent heat?
Energy used to break or forms bonds in rearranging molecular structure between two phases
What is humidity?
Amount of water vapor in the air
What is saturation?
Water in air reaches max vapor pressure
What is vapor pressure?
pressure exerted by water vapor in air
Evaporation puts what into the atmosphere?
Puts water vapor into the atmosphere
Windy conditions do what?
Disperse water vapor in air and evaporation increases
What is evaportranspiration?
Combined process of water vapor entering air from two land sources
Annual precipitation is greater than what?
Mass water vapor entering air from two land sources
What is relative humidity?
Ratio of annual water vapor to air’s water vapor capacity
What is dew point temperature?
Temperature air must cool to reach saturation
What is sensible temperature?
Temperature a person’s body feels
When does condensation occur?
Air must be saturated and have surface to form droplets
What is condensation nuclei?
Particles that serve as collection points for water molecules during condensation
What is supersaturated?
Further cooling of saturated air with no surface to condense upon
