-Refer to the diagram of a simple parcel above.What additional information would you need in order to be able to calculate the relative humidity of this parcel?
A)air pressure inside the parcel 
B)temperature outside of the parcel 
C)current temperature/capacity to hold water vapor inside the parcel 
D)current vapor pressure inside the parcel

Quizplus · Accepted Answer

To calculate relative humidity, you need the current temperature/capacity to hold water vapor inside the parcel to determine the saturation vapor pressure, which is then compared to the actual vapor pressure.
