Introduction
In class we have discussed a number of variables that describe or depend on the temperature, humidity
and pressure of a parcel of air. Although the relationship between all of these variables can be described
mathematically, it is also useful to develop a good understanding of how they relate to one another on a
thermodynamic diagram.
In this exercise, you have been given a table on which each row represents the
temperature, humidity, and pressure characteristics of the air found at a different level in a recent Greenbay
sounding.
There are 12 columns representing 12 different variables.
All but three of these columns are
blank for any given level. Your task is to use the three variables that are known to derive the remaining 9
variables. All but two (
