0. Overview
1. Introduction – The atmospheric continuum, physical dimensions and units, scale analysis, the fundamental forces, non-inertial reference frames and apparent forces, and 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, thermodynamics of the dry atmosphere.
3. Elementary application of the basic equations – The basic equation in isobaric coordinates, balanced flow, trajectories, streamlines, streamfunction, the thermal wind, vertical motion, and 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.
6. Synoptic-scale motions I: Quasi-geostrophic analysis – The observed structure of extratropical circulations, the quasi-geostrophic approximation, quasi-geostrophic prediction, diagnosis of vertical motion, idealised model of a baroclinic disturbance.
8. The planetary boundary layer – Atmospheric turbulence, turbulent kinetic energy, planetary boundary layer momentum equations, secondary circulations and spin-down. |

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。 |
