dimensions, and units, scale analysis, the fundamental
forces, noninertial reference frames and apparent forces,
structure of the static atmosphere.
2. The basic conservation laws - Total differential, the
vertical form of the momentum equation in rotating
coordinates, the component equations in spherical
coordinates, scale analysis of the equation of motion,
the continuity equation, the thermodynamic energy
equation, thermodynamicsof the dry atmosphere.
3. Elementary application of the basic equations - The
basic equation in isobaric coordinates, balanced flow,
trajectories and streamlines, the thermal wind, vertical
motion, surface pressure tendency.
4. Circulation and vorticity - The circulation theorem,
vorticity, potential vorticity, the vorticity equation,
the barotropic (Rossby) potential vorticity equation,
the baroclinic (Ertel) potential vorticity equation.
5. The planetary boundary layer - Atmospheric turbulence,
turbulent kinetic energy, planetary boundary layer
momentum equations, secondary circulations and spin-down.
6. Synoptic-scale motions I: Quasi-geostrophic analysis - The
observed tructure of extratropical circulation, the quasi-
geostropic approxi-mation, quasi-geostropic prediction,
diagnosis of vertical motion, idealized model of a
baroclinic disturbance. |
