This course provides an introduction to the thermodynamics, stability, and dynamics of the terrestrial atmosphere. It represents suitable preparation for research in experimental and theoretical atmospheric physics. It is also relevant for research in oceanography and planetary atmospheres. Topics include hydrostatics, atmospheric vertical structure, dry and moist thermodynamics, stability for small- and large-amplitude displacements, conservation laws, internal gravity waves, geostrophic balance, thermal wind balance, vorticity, circulation, and potential vorticity. Coursework involves analytic and numerical exercises, some observational data analysis, and reviews of papers in the Atmospheric Physics literature.
