Unit 7

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 (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.


Also is gamma the lapse rate for the environment? Small gamma is the environmental lapse rate (variable). Capital gamma or capital gamma subscript d are the traditional meteorological symbols for the dry adiabatic lapse rate (=-0.98K/100m).

What does   s denote? Saturated lapse rate of the air parcel (variable, changes with height and pressure). Think about why it does do that.

Class work

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