What are the four atmospheric lifting mechanisms? - ✔✔
-convergent lifting
-convectional lifting
-orographic lifting
-frontal lifting
Convergent Lifting (diagram) - ✔✔
Convectional Lifting (diagram) - ✔✔
What type of lifting causes cloud formation over Florida? - ✔✔Convectional lifting
What type of lifting only occurs in hilly or mountainous regions? - ✔✔Left: windward, DAR then MAR
Right: leeward, DAR
What is an adiabatic process? - ✔✔A change in temperature without the addition or removal of heat.
(Temp changes due to expansion and contraction of air)
Does air cool or heat up when it expands? - ✔✔Cools
Does air cool or heat up when it compresses? - ✔✔Heats up
What is the Normal Lapse Rate? - ✔✔6.4 C/1000m
What is the Dry Adiabatic lapse Rate (DAR)? - ✔✔10 C/1000m
, What is the Moist Adiabatic lapse Rate (MAR)? - ✔✔6 C/1000m
How can you tell if the atmosphere is dry or wet based on a Skew-T diagram? - ✔✔If the temp line (red)
and dew point line (black) are further apart, the atmosphere is more dry. If they are closer, it is more
wet.
What is humidity? - ✔✔The amount of water vapor in the air
What is the difference between specific and relative humidity? - ✔✔Specific is the ratio of water vapor
to air and does not change with expansion or compression. Relative is the ratio of water vapor to the
amount that would be present if the parcel was saturated.
Does warm air or cool air have greater capacity to hold moisture? - ✔✔Warm air
What is the problem with using relative humidity to tell if the air is humid? - ✔✔It is relative to the size
of the parcel (which is influenced by temperature of the air)
What is dew point? - ✔✔The temperature at which air becomes saturated
What is dew point a good measure of? - ✔✔How much moisture is in the air
What are the very comfortable and comfortable ranges of dew point? - ✔✔50-54F and 55-59F
respectively
What does air conditioning do to the air in a room? - ✔✔It dries it out
How does dew point change across the US throughout the year? - ✔✔couldnt find a good picture
