課程概述 |
本課程係以理學院,大氣科學系大三學生為授課對象,於每週一上午九時至十時,每週四上
午八時至十時上課,為必修課程。學程一年,上下學期各為三學分課程。
使用教材為Holton, J. R.,1992: An Introduction to Dynamic Meteorology. 3rd.
Ed., Academic Press, 511 pp.課程內容主要為:
0. Overview
1. Introduction - The atmospheric continuum, physical 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 approximation, quasi-
geostropic prediction, diagnosis of vertical motion, idealized model of a
baroclinic disturbance.
