Basic applications

  • conservation laws in isobaric coordinates
  • natural coordinates and balanced flow
  • trajectories & streamlines
  • thermal wind
  • estimating vertical motion, take I.

Circulation, vorticity, and potential vorticity

  • kinematics (diagnosis of airflow with dynamics)
  • circulation theorems
  • vorticity & the vorticity evolution equation
  • potential vorticity & the potential vorticity evolution equation
  • integral contraints on vorticity and potential vorticity

Linear waves

  • basic properties of waves
  • introduction to linear methods and wave solutions
  • linear waves of the primitive equations
  • geostrophic adjustment

Quasigeostrophic theory

  • simplified potential vorticity conservation
  • estimating vertical motion, take II.
  • application to weather systems
