What is the potential temperature (theta) for the air parcel at 700 hPa in
this example?
Enter your answer in the text box below, then click Done.
Answer: Theta (700 hPa) = 19°C = 291K
From the temperature at 700 hPa, follow a
dry adiabat dry adiabat down to 1000 hPa, where the value of the isotherm is 19°C = 291K = potential temperature (theta).
