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 approxi-mation, quasi-geostropic prediction,
diagnosis of vertical motion, idealized model of a
baroclinic disturbance. |
課程目標 |
課程開始時,先簡介大氣動力學的綱要,進而教授大氣之基本概念-單位,因次化,尺度分析及標準大氣之架構。繼之介紹基本守恆定律,大氣之基本方程及應用,環流、渦度之概念以及邊界層之理論;並將所學之概念應用於綜觀尺度天氣。 |
