Barotropic and Baroclinic Atmosphere
•Barotropic Atmosphere
•èno temperature gradient on pressure surfaces
èisobaric surfaces are also the isothermal surfaces
èdensity is only function of pressure ρ=ρ(p)
è no thermal wind
è no vertical shear for geostrophic winds
è geostrophic winds are independent of height
è you can use a one-layer model to represent the barotropic atmosphere
