Absolute Humidity
gram/cubic meter of air, actual amount of water vapor in air
Specific humidity
Grams/kilogram of air, weight of water vapor in the air
Relative humidty
Percentage (%) measures how close the air is to be saturated.
RH compares the actual water vapor in the air to the…
maximum water vapor that the air can have at a given temperature
How do you find RH?
(actual)
specific humidity
————————– *100
Saturation mixing ratio
(capacity)
The higher the temp
the fast it evaportates
The lower the temp
the slower it evaporates
RH -> 100% is considered
Saturated
lower the temp, Higher the RH means the air has a lower _____ capacity for water vaport
LOWER
Higher the temp, Lower the RH means the air has a lower _____ capacity for water vaport
HIGHER
DALR (dry abiotic lapse rate) =
5.5F/1000ft
WALR (wert abiotic lapse rate)=
3.3F/1000ft
LCL
lifting condesnation level (height)
What does Dewpoint mean
temp of air at which H2o vapor condesends
What are some high clouds
Cirrus, cirrstatus, cirrocumulas
whate are some Middle clouds
Altocmulus and Alstostratus
What are some Low clouds
Stratus, statocumulus, and Nimbostratus
What is fog
cloud base that touches the surface of the earth
Radiation fog
