  1. Chapter 3: isentropic analysis 3.1 isentropic coordinate system 3.2 isentropic chart interpretation 3.3 vertical motion on isentropic charts

  2. isentropic coordinates derivation of the equations of motion in isentropic coordinates: on blackboard isobaric coordinates isentropic coordinates pros and cons of isentropic coordinates can be found in this meted module, by J. Moore

  3. Isentropic maps: some examples infer vertical motion – low levels 285 K L 800 850 900

  4. Isentropic maps: some examples same time, higher level 295 K 450 900

  5. 295 K – relative humidity suggests that storm-relative motion has an easterly component in E Montana

  6. Isentropic maps: some examples same time, upper levels infer vertical motion – relate to QG argument 325 K 200 200 300 200 500

  7. 280 K sample isentropic charts showing winds, pressure, and winds • College of Dupage • OU 2014/03/28/12Z 290 K 310 K

  8. 2014/03/28/12Z

  9. diagnosing vertical motion on isentropic charts: impact of storm motion time 2 time 1 time 1 c (u,v)storm-relative = (u,v) - c This is discussed further in Section 6 of this meted module, by J. Moore

  10. vertical motion & diabatic processes layer perspective parcel perspective
