Unit 7

#thermodynamicChart
Thermodynamic charts. From: Mölders and Kramm (2014)

Learning goal

  • Examination of the vertical structure of the atmosphere with respect to stability and stratification
  • Being able to use of the material learned in previous units within the framework of thermodynamic charts and synoptic interpretation of the vertical profiles of the atmosphere
  • Distinguish and compare atmospheric stratification and stability

Students’ Tasks

    1. Watch this video on the material that will be discussed in class
  1. Read chapter 2.10 to 2.10.4.2 (included) of Lectures in Meteorology and take notes
  2. Be able to present the material learned
  3. Fill out the questionnaire by 1500 AST the day before class.
  4. Revise your answers in the questionnaire after the class, if needed.

The slides used in the video are here.

FAQ

Q: What does Γs denote?
A: Saturated lapse rate also called moist adiabatic lapse rate of the air parcel, which varies with height and pressure. Think about why it varies as a function of pressure.

Q: Also is γ the lapse rate for the environment?
A: Yes.

Q: What’s the symbol for the dry adiabatic lapse rate?
A: Γd

Class work

In class, we will discuss, among other things, these problems.
