Charney (1948): On the Scale of Atmospheric Motions Some key points

General equations of motion (conservation laws) Are indeed general Allow a wide range of behavior  Complicates working with them Need to filter out the “noise” Large-scale behavior of atmosphere is ~ hydrostatic ~ adiabatic ~ horizontal ~ quasi-geostrophic

Motivations Gain physical insight through analysis Produce simpler numerical weather prediction equations How do we implement these appropriately? (have a closed, consistent system)
