Farewell to L-grid - a vertical mode analysis Boundary condition: at

Separation of independent variables Horizontal structural equation: Vertical structural equation:

The result supports strongly a CP-grid ! cf. H.-J. Herzog and A. Gassmann: COSMO Technical Report No.7, 2005 and papers of Arakawa and of many others
