Variations on a beta-plane: derivation of non-traditional beta-plane equations from Hamilton's principle on a sphere
Starting from Hamilton's principle on a rotating sphere, we derive a series of successively more accurate β-plane approximations. These are Cartesian approximations to motion in spherical geometry that capture the change with latitude of the angle between the rotation vector and the local verti...
