Humidity
What's the formula for establishing absolute humidity
AH=RH X C
In which ways can latent heat be transferred
Absorption, evaporation, and condensation
List the ways to change absolute humidity
By adding or removing moisture
List the ways to change relative humidity
By changing the capacity or by changing the absolute humidity
Which phase of the Hydrologic cycle is known as the "Mechanical" phase
Coalescence
As temperature increases, relative humidity
Decreases
rime
Development of ice crystals
The three minor forms of condensation are
Dew, frost, and rime
List the phases of the hydrologic cycle
Evaporation, condensation, coalescence, precipitation, and run off
The two major forms of condensation are
Fog and clouds
Hygroscopic means
Having the affinity of attracting or absorbing moisture
As temperature decreases, relative humidity
Increases
Define Humidity
Moisture in the air
Explain the relationship of latent heat to evaporation
Molecules of latent heat get picked up during the process and latent heat is stored
What's the formula for establishing relative humidity
RH= AH/C (X 100)
What two types of information can be found using the psychometric tables
Relative humidity and dew point
If you see a cloud, you know that
Relative humidity is 100 %, condensation has occurred,
What are examples of a condensation nuclei
Sea salts, dust, ash, pollen, smoke
Which of the following types of humidity doesn't have a formula on the sheet used to work humidity problems
Specific humidity
Specific humidity is
The actual amount of water vapor that exist in a given mass of air that includes water vapor.
Relative humidity is
The amount of water vapor in the air compared to what the air can not hold. Expressed as a ratio
Absolute humidity is
The amount of water vapor that the air is actually holding. Expressed in grains per feet cubed.
What is a condensation nuclei
The center of a snow flake, raindrop, etc
Explain the source of humidity/atmospheric moiusture
The combines effects of evaporation and transpiration (Evapotranspiration.)
What is the relationship between the dew point and the current temperature
The greater the spread, the lower the reltaive humidity
What is the hydrologic cycle and how is it related to temperature
The process by which water moves in various stated from the ocean to the atmosphere to the land and back, It is related to weather because of its' potential for precipitation.
Dew point is
The temperature at which condensation occurs
What is the purpose of the air capacity chart and how is it used?
To determine water vapor capacity of any temperature between 0 and 100
When would you use specific humidity instead of using Relative or Absolute?
When attempting to assess water vapor mass versus water vapor volume.
How is dew point related to precipitation
You can't get precipitation until the dew point is reached.
As relative humidity decreases, temperature
increases
Explain the relationship of latent heat to condensation
latent heat is released through condensation
List the types of humidity
relative, absolute, specific
Absolute humidity will always
stay the same unless moisture is added or removed
Air stability is determined by
temperature
The capacity of the air to hold moisture is determined by
temperature
psychromter
used to measure relative humidity
