4.1. Definition of Potential Temperature

Try these first

1. 1.

   Define potential temperature.

   Hint

   Think about how it is related to pressure levels.

2. 2.

   What is an adiabatic process?

   Hint

   Relate to how air moves in the atmosphere.

3. 3.

   What is potential temperature often adjusted for?

   • Relative humidity
   • Pressure
   • Wind speed

   Hint

   Think about what keeps the temperature 'normal' at different heights.

4. 4.

   True or False: A rising air parcel cools adiabatically in a stable atmosphere.

   • True
   • False

   Hint

   Consider stability effects on rising air.

5. 5.

   Analyze a case where the potential temperature shows a decrease with altitude in terms of atmospheric stability. What would be the implications for weather conditions?

   Hint

   Consider how instability influences vertical air motion.

6. 6.

   Create a scenario where an air parcel at 500 hPa with a temperature of 280K ascends to 1000 hPa. Calculate the potential temperature using R=287 J/(kg K) and Cp=1005 J/(kg K).

   Hint

   Plug in the values correctly into the formula!
